Regarding the RU-vid comment you talked about. The Person that doesn’t know how to repair his Boat/Car or Lawnmower might just be a Doctor or Scientist or Airline Pilot… a person like ME who can repair almost anything that’s repairable could never ever become a Doctor or a Scientist or an Airline Pilot… that’s because I could not do the studying required to achieve these professions, this I know. I hope y’all are getting my point. Everyone has their “Niche”.❤️
Nobody i know fixes boats on the water. Maybe 5% keep even tools in the boat. You keep your safety gear and required items. Even me ive had the same boat for 12 years since new and know everything about it. But if i have any issue i trailer it home anyway. Its also not environmentally friendly.
@coastalcleaningandmaintena2884 neither are electric cars I mean just to build 1 electric car leaves about the same carbon foot print as building and then driving 1 gas car for 10 years
The unfortunate truth is that today you should specialize in something and not know how to do anything else, that is how you will make a big salary and pay everyone else to do things for you.
Had a 70 once . Tha motor was indestrutable. 20 years zero problems. Of course it was winterized every year and well maintained . Very fast very dependable and always started in seconds. Traided it and the boat off on a 19 ft. Bayliner with v8 in-out. Love my boats. But its true. A hole in the warer you pour cash into. 76 now but my kids , my grand kids all benifited greatly. Miss those days.
My grandad had a Johnson 65hp looked just like this brought back a lot of great memories of fishing and skiing. Great to see an old outboard still going
Brandon, Sonny here, I'm a 36 year J/Evin. tech in Wilmington, N.C. really enjoy your channel! You have the right blend of seriousness, humor, and humility (the latter is lacking badly in many outboard repair channels!)!! Keep up the good work!!! Some simple tips .. always assume fuel hoses are old, & replace them (90%+ outboards have 5-10 y.o. hose!)!! Of course if you know they're very new don't!! Lol! It's better to err on the side of preventing call backs, than to encourage them!!! Also, you may already know this one,, when replacing exhaust cover gaskets, wipe ~acetone~ well around the aluminum exhaust plate & cover after removing the old gaskets(s). Then after applying the gasket sealer to ALL ALUMINUM SURFACES allow the sealer to cure for 30 - 60 minutes before installing those parts!!! After bolting them in, re-tighten/torque them 3-x's!!! Allowing some time when you make the 3rd try!!! This way you're compensating for the squeezing out of the sealer, which cancels out your torque specs. Be on the lookout for early 90's 3 cylinder Mercury 90, 100 h.p. 2-stroke motors!!! Don't know if you've already experienced this,,,, but the factory messed up the tolerances between the cast iron cylinder sleeves, and the cast aluminum block(s), allowing the sleeves to get loosened when at temperature, and ~move~ backwards, towards the crankshaft,, and then the top piston ring releases itself because the sleeve moved back towards the crank!!! I guess you know the end result, lolol,, because Mercs don't have any cylinder heads, you'd have a mess!!!! Just thought I'd mention that one!!! Cheers to you~!~!~!~ Sonny.
Totally agree with you! I've learned via your channel and others how to work on my 1989 Johnson 88 SPL and it runs like a top! I did have a local shop do my last water pump change just because it was over 10 yrs since it had been done. They were the ONLY shop that would touch my motor! So I'm now planning to do my own next time and thanks to you, I think I can tackle the job! Not bad for a 62 yr old geezer to still be learning! :)
I once had a 1986 Lund “Mr. Pike” with a 70 hp Evinrude. The boat was awesome. But what I like the best on it was the engine. Nothing ran and sounded sweeter than that Evinrude! If I come across something like that, I will be very tempted to get back to that type of boating. It was so fun.
Love those 3-cylinder OMC loopers - especially those 1978 and newer with integral power TNT. Some of the best two-cycle outboards ever made........... Thanks for the video, Brandon.
Yes, actually they're all a little over-powered! The #2 connecting rod(s) very often let go, and BANG out the side of the block!!! In 36 years I've seen so many of them through a rod. If you detune them they'll live longer!
@@newmoon54 the real story is these motors were born as 75 hps.., they were detuned by making carbs with small throats and jets.. put a set of 75 hp carbs on a 65 or 70 hp and they run great and last a long time
Great Video, Great you were able to figure out were the water was coming into the bottom piston, I had a similar problem with a 20hp merc, the bottom seal on the crank let go water came up into the crank, then it was left for years, when I got it it was locked up, took it apart, changed the seal and the bearing, ran great, yep lot of people operate things that they have no idea how to fix, that's were guys like you and I come in,
Finally someone has shown how to remove the carbs on these. I have this engine at home and I went on to a lot of sites and they said that a link sync had to be done after removal. I can see now that this is not the case. Thanks so much for going through this easy repair. I owe you a beer. All the way from Australia. Thanks Brandon.
Don’t know if I will ever have an old two stroker again I’m almost 100% in saltwater but I’m very mechanically inclined and these old engines just bring back memories. I remember grandparents having these boats when we were kids and we learned to swim by getting thrown overboard in the brackish water and you figure it out.
Never go by what you see outside when there's a hurricane coming. We did that here in Miami Florida, in 1992 we were affected by hurricane Andrew a category 5. The day before the hurricane, it was such a beautiful day there was no wind and the sky was blue.
I used to think these motors were boring (I'm more into 1950's outboards), but have started to gain an appreciation for them. Your is super clean as well (I'm so used to seeing ratty ones purchased on the cheap at the boat ramp that crank and crank and won't start). Sounds great as well. This video makes me want to keep the 1974 twin Johnson 50 HP Loop Charged outboards on my great grandfather's 1960 Alumacraft Queen Merrie, that was recently brought home from my family's cabin. I had always planned on switching them back to the twin 1957 Johnson 35 HP (red and white) outboards it was built with. Maybe I'll leep the 50's on it for awhile now. They're growing on me :)
You make it look much easier than it actually is. There are many roadblocks to repairing these old guys. For instance, I have a 1959 Johnson 35 horsepower, and while it is a very simple machine, it can still confound me. For instance, I went to replace the points, and despite doing it several times before could get no sparks out of it. I have the timing fixture that uses the marks on the Armature plate and use a meter to determine when the Points Break. It's a beautiful system, but for some reason I could not get it to work this time. I finally figured out that the points I purchased were from China and both were defective. That 70 horsepower Johnson is just beautiful. Advice for men and women who wish to repair these and keep them? Without question. Join your local chapter of the antique outboard motor club and get to know the old-timers. They are an invaluable library of information.
Those china points, jeez, what a problem. I'm sure many people out there are throwing out the engine because they can't figure out the new points are the problem. I don't think there is a local chapter. If there were, it would probably just be me.
I own a few 2 cyls with that mageto and fixed a lot more, but I have never bought a new set of points. Coils I can't count how many! And the 18-5181 are great. But I've always just cleaned up the old points and tested and reused the condensors.
Job well done - when you said "she is this doesn't go OK to just pull the plug", I thought hell no, he'll get it running just because he can. Would have really been a shame to see an old boat like this get thrown out.
Hard to say why most people won'r even consider trying to fix things. I think it's a multi-factored issue. At the top of my list is the need to spend considerable time in acquiring basic knoeledge and skills needed to ensure outboard aintenance while these days, time is the least available commodity. Regular maintenance of 2-stroke motors including carb cleaning is definately within the technical reach of most owners but then, getting one's hands grease dirty is not very valued activity anymore. Thanks for your great videos !
Awe we used to run those 70's and 75's on raceboats :) The short shaft models :) with clever props. I too know those engines inside and out too . Cheers to an awsome video Brandon :)
Nice video. I'm currently resurrecting a 78 johnson stinger 75. Seized steering, trim motor wouldn't go, about a meter of control cable missing (can you believe that someone saw fit to remove a part of an 8 wire cable?), no key, no battery terminals, but good compression and looks fairly well kept under the cowl that is. I've got her running and steering now, but the carbies will need cleaning. She is an ol girl worth saving. Labour of love, as are most boats.
We had a 1968 100 hp golden meteor, we water skied every weekend. Had to clean plugs every second trip and ran carbs dry every trip. Other wise a c ery reliable motor.
Holy cow I could not agree more about the Idiocracy comment,as for people not being able to repair their own equipment comment well this is why we have professions such as car, mechanic, boat, mechanic, aircraft, mechanic, plumbers, electricians, etc.
I had the same problem with a 1972 Evinrude Triumph 65hp 2 stroke. The problem was some debris floating in the water floated into the prop and up the exhaust pipe. When the engine was out of the water it ran fine, but in the water the debris rose up the exhaust column and occluded the exhaust port causing the engine not to run. when pulled out of the water, the debris dropped down allowing the engine to run.
Dirty clogged carbs are usually the death of these motors. People trying to run them clean don't consider how lean they can be running certain cylinders.
I have a 74 Evinrude 70hp I have been wanting to go through for awhile to replace the 61 Johnson 40hp on my old 1958 Duratech. Too many projects and life getting in the way....lol
I love that boat,,,,, I'm currently looking for one here ,,,, but I'll be either rebuilding the motor or replacing with a four stroke, depending on the set up,,,, those cathedral bow riders are awesome for what I want
Stumbled across your channel and think I’ve found a keeper! Great videos and well explained troubleshooting. I’ve subscribed and will enjoy watching the rest of your videos. 😎
Found your channel as my brother and I are trying to figure out how to replace a busted piston in a '73 Evenrude 85hp. Very useful content, whether we succeed or not. Thanks for the help!
Your presentation was just fine. i did not believe that the carbs could gum up that bad, I'll have to get to the carbs weather I want to or not. . Thanks
Probably would help to replace all the seals and rubber hoses. Over time ethanol destroys those components. I should know, I had a '77 70hp Evinrude and a '95 70hp Johnson. Now, I only use non-ethanol gas even though it costs more.
I did a carb clean on the exact same motor on one of my boats. The bottom carb had about 1/8 inch of sand in the bowl. Only time I've ever seen something like that.
Around 1976 or so, my father was considering buying a boat, it was a small cathedral hull bow rider of that time, just like this boat. It was yellow, like this boat. And it was called “The Thing.” He didn’t buy it. Is this it? That’s my Rosebud.
A genius is the person that respects when they SHOULD NOT try to fix something. I am no genius, fixed lots of things and had my boat quit many times in the lake. Always made it home. 30 years as a mechanic here.
A picture is worth a thousand words. Most people would be lost on a computer if it were not for the graphical user interface that allows the computer illiterate to use one. I agree “Idiocracy” is becoming a reality. Things are getting so easy for people to go about their daily routine that a lot of people think they are really smart and don’t see any reason for expanding their knowledge base unless they are looking to earn more money.
Brandon I think the pics on things may be due to communication to different languages possibly but you are right about that society is not as smart Chris from OHIO
I had a 1976 70 foreverude. thing had a million hrs. on it when I got it in the late 90's. only problem I ever had was that it started dropping spark to one cylinder when the powerhead heated up. Turned out to be the exciter coil under the flywheel.
Had the same issue with a 70HP Evinrude, would rev nice out of the water but wouldn't get on the plane. Turned out to be top carby's float was stuck starving fuel to top cylinder.
My parents had a 16’ VIP with this motor on it. We drove the dog sh*t out of that thing. It was literally the slowest boat in the family but it ran for years.
That crossed my mind as well. The crankshaft seals has probably not had time to soften up to do it's job due to lack of use. Similarly the Rev counter & speedometer has not had the use to keep all functional without tinkering eh ?
You are absolutely correct about the Idiocracy thing. We talk about how the country is getting dumber and its turning into the idiocracy movie more everyday.
I remember the days when all cars were manual transmission you had to pay extra for automatic transmissions I’m in my mid 60s and I learned how to drive a car with a manual for the first time I was amazed first time I seen automatic transmission
Whoever made the comment about not being able to fix the engine is somewhat of a clown. It is very important in life to know your limitations and live within them. I do HVAC and the worst customers are the ones who think they know it all and attempt to "fix" the unit themselves.
Really enjoy your videos! I recently purchased an older 95 Bass Tracker with a 40 HP which required a bit of maintenance. I rebuilt the carbs, new plugs, etc. I would like to add trim/tilt to it, I also live in Arizona just east of you in Flagstaff. How do I get a hold of you and possibly speak to you in regards to you doing a bit of work on my boat, Hope to hear from you soon! thanks again!
@BrandonsGarage had the carbs rebuilt , would only run 3000 rmp wouldn't plane out , got to messing with it , found at wot , butterflies still could open another 25% figure they didn't adjust the linkage right , should run 5000 rpm.. but other that that worked find after warmed up
Hey Brandon thanks for putting up this video. I have this motor. It looks easy to pull those carbs. I thought I had to do a link sync if I played around with the lever mechanism. Is there a chance of damaging the links when you are freeing the carbs from the outboard? It looks like you just levered them off.
A '74 70HP Johnson with only 38 hours?!? Its barely broken in for goodness sakes!! 150 compression?? Id take this motor over ANY 4 stroke in this HP range. These were/are great motors, reliable and strong. This is a sharp little boat, beautiful.
i was always plagued with 2 major problems with boats not running , the first exactly what's mentioned , the second was runs great for a few minutes then dies and won't restart ...
My 90 Merc had plastic carb links, thanks Mercury. Yes, they broke the 1st time. 9 out of 10, it's the carbs if your engine won't start after sitting a while.
Is 150 psi compression normal? I have a 1974 Johnson 135. I checked with a cheap harbor freight tester and got 113-115 on all four. is that low? It runs great.
Greetings, I have a 1975 Johnson 70 HP. What do you recommend for good engine maintenance? I bought it recently. What would I have to do for maintenance? also to the lower unit trans.
I'd love to see a complete rebuild on one of these older 3 cylinder 2 strokes like you did with the 9.9 a few years back. I inherited an 83 70 hp from my dad that he blew up. Rod bearings went out on the top cylinder and that was that. I tore it down to find the issue. Once I found the issue just decided to completely tear it down and find parts to rebuild it. That took ALOT longer than I expected. I got all the parts but now I forget how to reassemble everything. I did take pics, but nowhere near enough.
