Still run a tower of power today. Over 30 years of trouble free service and it can still wup the modern day equivalents. Simple and effective.

@joshalger6059 Месяц назад

They are excellent engines. My uncle still runs one he bought new over 30 years ago. It’s out a good bit every year. Carbs rebuilt a few times but engine never been opened up. Still runs excellent and it is a joy to run and listen to! My favorite part is the first cold start every year when we take it out for the first time after sitting all winter!!

@andyharman3022 Год назад

You've outdone yourself with this one, VisioRacer! This video pushes my buttons in a few places. The footage from Lake-X in the 1950's showing the test boats running durability is extraordinary. I worked on a team testing an offshore powerboat at Lake X in 1998, and the employees there still talked about the durability test program that Carl Kiekhafer initiated. He was said to be a firm taskmaster and insisted that the endurance testing proceed nonstop, regardless of conditions. Difficult yes, but this is how excellent, reliable products are developed.

I grew up with 2 stroke dirt bikes but never owned a boat, until recently. My wife wanted a small “tinny” (we’re from Australia), but I found a dirt cheap ski boat with a 1978 90hp tower of power. I’m fixing up this engine and love the design of it. This is a great piece of engineering , so far ahead of its time. You covered this well in your video. I am so proud to own such a classic engine. It’s great to see you do a video on the tower of power (I’m a big fan of your work). You are not quite right about the availability of parts for these though, they have a cult following and there are still lots of parts available (at least for my ‘70s motor). Short of major failure, it is easy, (and cheap) to keep this engine going.

@07zx14White Год назад

Man I miss my old straight 6 merc. I had a Glastron Carlson CV16 with a 140 horse tower of power out back. It shot that little Carlson 16 around like a slingshot. I bought an 18' Fabuglas tri-hull from an old man that had the 'like new' Merc on the back. He said he bought the motor new to repower the tri-hull but only ran it twice because sudden health issues arose. So the new motor and old boat sat for over 10 years in his garage. He sold it to me for $2500 but I had to take the old tri-hull with it. All it needed was a carb clean and three new updated floats and it was perfect, not even a single scratch on the skeg. I removed the 85 horse Johnson Hydro electric shift from the Carlson and mounted the 140 horse tower and a love affair was born. By far the best outboard I've ever owned. Just electric smooth and endless torque at all throttle ranges. Boy I miss that whole time in life. Anyway that's my tower of power story.

@Dgadude Год назад

My father had a Four Winns Horizon 170 built in the 80's with a 115 horse 2-cycle straight 6 outboard Merc. Started riding on the boat. sometime at the age of two and the boat was in the family up until about 10 years ago. Same engine. I have hundreds of hours driving that boat and my father always serviced the engine himself. The "tower of power" was massively powerful for its size. It was loud and buzzy but had plenty of torque on tap at any RPM. When you got up to around 5000 RPM, you would slam the throttle wide open and even though the boat only had maybe another 20 mph to go, you were thrusted hard back into your seat and the engine screamed across the water. It made 40 mph feel like 80. The motor was always smooth outside of idle and shook violently at idle from the torque. I miss the days of that engine and the sound and power at WOT.

@trustyoldiron5416 Год назад

My grandfather bought a Glastron in the late 1970's with a 140hp tower of power with "Power Shift". He had it for years in Montana. It wound up outlasting my grandpa as he passed back in 2018. The boat and motor both still exist and are still running. My aunt now has them in Washington.

@jadenantal1652 Год назад

@lynn4205 9 месяцев назад

I have a 140 also with a last of the inlines warranty engine that poped,popped, guessed it # 3 cyl. By then mercury didn't want the power heads back ( 88 /89 ) So I got the crank assembly,put one new piston on it the stuff it into the 140 case. Had power ported pistons. The difference between 140 and 150 was the power ported pistons as I remember. Ports were huge as compared to the 90 115 hp. Still have the engine yo this day. Never started it either . I also put the carbs like the BP model used. No back draft carbs. But carbs were same everything except one demention. I got pretty proficient at dropping the cranks in the cases as I was taught by little guy who was an instructor at Foundulack Wisconsin school. Use the Scizzer ring clamps have the rings exactly in the center of the pin an if I remember correctly #1and 6 were down so they went in first the the rest just a little wiggle and they were in. I'll never forget this guy. And when it came to shimming a gesrcase he could tell you you need .002 " more shims to be exact. And he would be correctl ! And it was by feel for him. No dial indicator !!!

When I was a kid we had a Mark 75 on an 18 foot aluminum boat, the motor never gave us trouble. We had that motor for over 10 years, my parents and us seven kids all learned to ski behind that boat, those were really good times. Thanks for the memories. 👍

My grandfather bought a Mercury 1350 in 1971. He learned to ski behind it, my dad and uncles, me and my brother and now my kids are learning to ski behind it as well. 1 major break since 1971, crankshaft broke, and nothing else. I am 95% done restoring the boat. Just need a new paint job and sticker kit on the engine, then it will look like it came from the factory... But the engine restore will have to wait for May 2023. Summer just started in South Africa and I'm taking it out to the lake next weekend... It's a beast. And it's a beauty. It's family... Love my Mercury 1350... If it dies on me completely one day, it will be put inside my garage as a work of art. A family heirloom...

I had a 150hp tower of power on a 15ft Bullet ski boat. It was obviously overpowered but a lot of fun. Very thirsty on fuel. I still can’t believe how smooth it was on idle. Never gave me any problems other than a starter motor issue which was an easy fix. Great memories. Thank you for the story behind the beast.

@alansmith7833 Год назад

I grew up around mercs as a kid, my parents always had boats, and they always had mercs on them, a few were the tower of power, and impressive they are, riding in boats, facing that face plate cover, listening to incredible sound of the tower of power, awesome, absolutely awesome, pretty safe to say there is nothing like it!

@Bata.andrei Год назад

I used to own one of those. Mine was the 85hp version. I got it with a damaged lower crank case due to corrosion. Never got around to fixing it. Ended up giving it away and never heard it roar. I just love the sound of an angry multicylinder two stroke.

@iBackshift Год назад

In the early to mid 80's I spent several dozens and dozens of hours behind a 90hp ToP Merc either waterski, wake board or driving the boat. My fave sound is when you put in forward [towing a skier] and get ready....Full throttle. Its the sound of the engine accelerating from above idle to 3600 rpm, that loud carburetor sound of the engine pulling HARD, and then back off to about 3100 to pull whoever was at the end of the rope. Im an OMC guy, but the "Tower of Power" is my fave engine right beside the V-4 OMC.

@deckert618 Год назад

My Dad, a fairly prominent outboard racer in the 70s and 80s spent many weekends at Lake X, but he was ultimately an OMC V6 fan. Of course, Merc dbuted the Black Maxx just a couple years later and the war was on again. Good times.

@dirtmudsnowandwater Год назад

Lets see, describe a tower of power to someone who's never.... Horrific fuel consumption. They really slurp up the gas. Kick over cans of fuel as fast as you can, the merc will still use more. Fantastic sound at high RPM on plane, they almost fluctuate like a rev limiter but slower, and can run that fast all day. Disturbingly smooth running and quiet at low speeds. crisp and abrupt acceleration outta the hole provided it has a good propeller for the task My dad learned to ski behind a direct drive I6 "DOCKBUSTER" and had mentioned how difficult it is being that theres no "idling" its either forward, reverse, or off. So hitting the throttle on time with the skiers reflexes and driving the boat took some finesse and definitely added frustration. Vizioracer, Thanks for documenting these unique engines for the masses. They mean something to me.

My uncle had a ski boat with an inline-6 Mercury outboard when I was a little kid, I remember riding in it a few times and always thought they sounded cool. I have a 9.9HP mercury 2 stroke outboard from the late 70s and it still runs great, it's smooth, responsive and quite fast. A bit thirsty though.

@charleslum2438 Год назад

I worked on these engines for 40 years and the inline 6(tower of power) was the toughest outboard out there we took them right from mercury marine and put them on our boats at Eldocraft boat company in Smackover Arkansas and ran the crap out of them with no failures but the when the V6 came out it was a different story. They would not hold up like the old 150s . The 155XD ran well over 100 mph on an Alison craft single hull and was the fastest thing on the river back in the 70s. That thing would scare the shit out of you.

@j.d.saccociates3313 Год назад

tower of power! I've got a 1984 90hp unit. It's a fantastic way to turn fuel into smoke and noise! the fuel consumption alone is enough to make the engine obsolete, but theres something about it that just makes me smile.

As long as I've been alive, my uncle has had a vintage fiberglass boat with a 150 Tower of Power on the stern. I always assumed naturally that all outboards were light, mean, and 2-stroke. Did not realize until later how special those motors were. Then later to really learn about 2-strokes and discover they were actually ramp-piston cross-flow caveman technology, the performance is all the more impressive.

@katalist7747 Год назад

My grandfather had one, 110 hp i think, it hadnt started in twenty years, he wanted to sell the haynes hunter boat it was attached to, we figured a running motor would help the sale, all it needed were new ignition wires, since the old ones deteriorated, it fired right up and even idled well, they were built well and very reliable

When I was a young boy, we would occasionally rent a ski boat at a lake near our house. It always had the "tower of power" and as a 5 year old, I was terrified of it. It sounded like a monster and moved back and forth by itself (I had no idea the steering wheel made the engine move).

Owned a 1993 Merc fuel injected 2.5L V6 150HP to 20 yrs. What a dream engine. Power galore and good low end, smooth flat power band and great torque. Wide open throttle from a start would spin the 3 blade SST prop instantly up to 2500RPM, the prop would be digging in and it would shoot the boat out and pull hard and steady to 5400RPM. Trimmed out it was a rush hearing it howl down the lake.

@arthurjennings5202 Год назад

Love the video. The Mercury engine used a deflector piston to scavenge the cylinder that did not produce the power of a loop scavenged engine. The Mercury bottom end was used by Quincy, who created a loop scavenged cylinder and head assembly that used dual exhausts for more airflow. The engines were 15 cubic engines, 20 cubic engines of twin cylinder configuration. 30 and 40 cubic engines were 4-cylinder engines. The most powerful was a 60 cubic inch six. The 6-cylinder engine's exhaust note at speed was best described as a shriek as it screamed across the water with six open pipes. This engine series dominated outboard hydroplane racing in the early 60s into the 1970s. In the 1970s, Koenig, a German engine company produced a loop scavenged boxer engine layout that used a rotating plate or "rotary" valve to control the air intake into the crankcase instead of reed valves. The two opposed pistons gave better crankcase compression, resulting in better scavenging of the two opposed cylinders. Koening built two- and four- cylinder engines with this layout. I don't know if they built a six cylinder.

@lynn4205 9 месяцев назад

Oh those LOOPERS. Had an A (250) owned by Rodger Dykhouse. Dad bought it off him after he won the nationals in Depue I believe. Had a Koning B converted crossflow to Looper one pipe hi the other on the other side low. Miney Marton owned it. Do you remember Chuck Whites sideways F roundabout? Stacks point toward the shore to compensate for the torque of that old Alki engine which got him around the corner quicker. Also Lake Sanford in Midland Mi.. I saw Billy Seebold down here (fL). At Sanford for the tunnel boat race in I think 95. I said BILLY? HE LOOKED AND ME AND Lynn Jones? How is your mom, dad and twin brother !!!! I hadn't seen Billy since 68 or nine when he was still running the D alki's. RING OF FIRE runnabout and hydros. Got hom to sign one of my race brochures from the days gone by at Ohio Champ boat race.

We were both 16 and I worked as the official watcher in the boat. All boats pulling skier(s) had to have both a driver and a watcher by law at that time. The club boat had a big ol' red and cream-colored Merc inline which was IIRC a Mark 78 and IIRC was rated at about 60HP. I couldn't tell if it was a 4 or 6 cylinder but man would that old girl push that honkin' heavy club boat !!

Used to have a boat at the cabin with a Mercury 1500 in the gloss black with blue accents. Wasn't ever running 100% but I'll always remember loving the sound as a kid when she was running.

@MrRecall200 Год назад

I have a last year 115 tower on a 14 foot ski boat. I absolutely love that motor. If it eventually smokes a cylinder or fails I will absolutely rebuild it. So much power for the weight, and the looks and sound are awesome too. Fuel economy can be impressive both ways. At wot I can blow 5 gallons in 30 minutes at about 6100 rpm. But at 32mph cruse, right about 3500 rpm I can cruse for hours on 5 gallons. The 24 pitch stainless and all the tourqe to make good speed at low rpm are actually a great combo. I was shocked to find out just how good it can be on gas when your not laying in to it.

@Thatvolvokid96 Год назад

I've operated dozens of outboards, and owned a tower of power. It didn't start easily but it loved high rpms. It was a 90hp on a heavy 17' hull from the 1970's and it got up to almost 50 knots

@kevindickerson6306 Год назад

Had a pair of 1996 3.0 lt. two stroke, V6 250 hp with EFI on a 27' ,red hull, CV center console with Armstrong engine bracket, weighting 7500 lbs. Top speed 68 mph at 5800 rpm. These engines would cruise all day at 4800 rpm. The 10 years we owned the boat in Florida, running summer and winter. Never had a mechanical failure. Only two secondary ignition coil packs and two trim and tilt electric motors failed. These engines were power monsters and bullet proof. The engine water pumps and lower gear units were serviced every two years. I miss the boat, it was a good ride in rough waters. They loved fuel , 16 gallons per hour, each engine @ 45 mph. Nowadays I'm resigned to a 20' center console with a single 2008 four cylinder 2.0 lt. DF140 Suzuki four stroke. Bullet proof and fuel efficient. Also a great engine. Crusing speed 30mph at 4500rpm , top speed 42mph 6050 rpm.

@jamesgeorge4874 Год назад

Fantastic as always, I grew up on the Great Lakes, the tower of power was always a favorite, Mercury also has a fascinating story about the development of the Inboard/outdrive system, developed by Jim Wynn, who Kikehaefer dismissed as folly, whom left Mercury, to build it for Volvo, then, a few years later, developed an I/O for Mercury, that would capture 80% of the pleasure boat industry a few years later, again, almost as if Carl just stumbled into success.

@Wingnut353 Год назад

To be fair... Kikehaefer was correct to a large extent, inboard/outboard boats have very low resale value because the inboard/outboard seals and complexity isn't worth fixing..... compared to outboard boats that last essentially as long as they are properly maintained, winterized and stored.

I had a 10hp Mercury Lighting outboard. It was an early model from Mercury that had no transmission, when you started it you were moving! To reverse you simply spun the motor around backwards. Rumor had it that made more like 15 ~ 20 hp but was marked 10hp due to engine restrictions at many lakes. In the late '60s/early '70s my father bought a 115hp "tower of power" with power tilt (hydraulic rams to alter the engine trim while you were moving) for an 16 foot Chrysler "Fury" tri-hull. It was kind of flimsy but light boat and with that engine would do over 60mph when trimmed out. Fun days as a teenager living on a lake.

@andykerr3803 Год назад

These were very special motors. There was no separate cylinder head. So you had a blind cylinder block where you lowered all six pistons and crank down into place. To raise the compression or cc the chamber you would weld on a small portion to the piston to be accurately milled down. No cylinder head gasket at all, of course. The crankcase did have very low volume for superior cylinder charging. Some racers reduced volume even more by wiring balsa wood on each side of the connecting rod. These were ball bearing crank and rod journal engines with superior lubrication. In addition to that 50,000 mile test, the big factory racing sixes would go over 50 races without a teardown... Unheard of today. The 4 cylinders were also a classic race motor. The 5 cylinder was a "Force" outboard based on the 4 cylinder Chrysler. The 4 cylinder 150 hp open header race motor Chrysler was very successful, but not well known. Chrysler was originally "Westbend" and the designs were very different than Mercury. Less durable, but light weight. Super video, thanks. Entertaining and educational. "A big woman needs a black dress.." Strang's mother 👩‍🔧🤦‍♂️

Arghh. Force. The bane of outboard ownership. You are guaranteed to lose compression and have to junk the thing. Straight Merc 2 stroke will last multiple lifetimes just as the old Evinrude 2 smokes. I only run those 2 on my boats. Simple, love the smell of 2 stroke exhaust on an early winter morning of duck hunting. Nothing better than that.

@andykerr3803 Год назад

@@OttoTheWeim Yes, I saw few Force motors in action. A few of the expensive 5 cylinders being sold for scrap prices. Bad production. The quality of alloys was good. The design excellent. Yet, they are all gone now. Even the older Chryslers outlasted them. Mercury made them second rate on purpose to make their brands... Mercury and Mariner look superior. Dumb game.

@OttoTheWeim Год назад

@@andykerr3803 I had a newer (comparatively in their line life) force and it was horrible and bad compression. Replaced it with an even older (late 80s) Merc 90hp that runs like new to this day. I run older 2 strokes (evinrude and merc) from the late 80s to mid 90s by choice and seek them to install because they are bulletproof. I run year round including in subzero and the 2 smokes are always reliable and simple. No crazy computers to fail. Grew up on Mercs but grew a love for the abuse the evinrude will take. I don’t run the big motors just 35,70 and 90hp but they are built like tanks.

@j.thomas7128 Год назад

7:42 Leading to one of my favorite engines of all time; the Mercury 2.5 liter V-6. It's an amazing engine. The 2.5 was eventually available as a 300hp, 9000 rpm, factory built motor that weighed only 375 pounds. Race teams had this motor spinning up to and over 11,000 creating 400+hp. The sound of the Brucato SVS intake combined with the offshore exhaust (equivalent of straight pipes on bikes) made this thing sound futuristic and almost alien as nothing sounded like it. You'd hear it from miles away. I had one on a lightweight 19 foot catamaran and it was SCARY FAST! Folks would cheerfully ask for a ride while at the docks. A couple of times, they returned to the docks crying and sobbing from fear. What a great time that was.

Personally never been a fan of the look of the newer 'tower of power' design, but the old ones look amazing! and you cant deny they sound awesome! I started driving our speed boat when I was about 6, its had 3 outboards in my life, a 75 evinrude, a 60 johnston and now a 4 stroke yamaha 60. Gotta say, the 4 stroke is a gamechanger, you couldnt really cruise efficiently with the 2 strokes, but they were quick. actually having a wide power band is super nice with the 4. If you've never driven an outboard, its quite a different beast, as the steering and power are delivered from the same spot in the rear. no difference to a car if your just cruising around, but when your doing more "fun" things, its an absolute blast. racing, skiing, slaloms (if you get it right you can swing the rear end out in a kind of power slide. get it wrong the boat will turn itself over), swell surfing (our boat has almost no wavebreaking, so if you have to navigate swell, you have to work with the wave, hard work, but super good fun). Awesome video.

I purchased a 82 115hp tower of power with a bad piston last year that never saw salt just because the history of these motors. And just for giggles I tried to take it out like that before rebuilding it, it still hit 40mph only being a 5 cyl with no piston rings left at all on cyl 3 and a cracked piston and leaking baffles, just to show you how tuff these motors are even when broken. I wound up having to strip the block down and send it to Florida to on of the few good old timmers in the country who can machine these blocks still and bore or hone it out with its blind piston holes and non removable head plate, along with somenwho owned and operated a bridge port with an end mill to be able to resurface the exhaust baffle plates mating surface which are recessed into the block and notorious for warping and leaking water internally when the motors get old. I put it on one of my old boats and the thing screams like a Banshee. Now I'm taking the bottom half of a 72 sports craft safari 17ft and stuffing the top shell off a 69 cobia sea queen 18ft to build a custom boat for the rebuilt motor.
