In '79 I owned an 18' Glastron that I mounted a Mercury 150 to. I got it up to 80 MPH on Mission Bay, in San Diego, early on a Sunday, before the water got choppy. I knew it would go faster w/ a few mods to the carbs and intake. Along w/ a larger, cupped prop, that got my little beauty just up to 100 MPH, the next weekend. What a kick!
@@v.e.7236 a 150 on a heavy cvx-17 would do MAYBE 65-68mph and thats really set up perfectly w. all the goodies and a blueprinted hull. those boats have no pads, and really make them a handful at anything over 60mph or so. 100mph is possible, but you'd need double the HP easily.
The mercury test plant was in my stomping grounds So Sarasota Co. I used to go out and run with the run-a-bouts that would literally run circles around the larger slower boats to keep them all together for safety. I'd go run with them now and then, always a good time as I ran OMC's on old race boats propped out so tall they'd barely get up on a plane but when I did none of the Mercs could stay with me. That was 45 years ago, the good old days for sure.
My team set a world record with a 7 1/2 hp. We went a little over 72 mph and it wasn't a mercury. Champion spark plug company had them built just to outrun mercs, rotary valve engine that friggin screamed
Awsome video.. Great doc.. Being a prop tech i wish i had a better view of the prop and the lower unit. I assume the lower was 1-1 ratio.. Anyways thanks soo much.🔤😀🐟🐟🐡
They mention Hugh Enthrop, but they failed to mention Hugh Enthrop was the wind tunnel expert for Boeing Aircraft. I watched him race for several years, if Hugh showed up the rest of the racers might just as well put their boats on there trailers. Yes, his designs were that good. F class as I recall ,alkie burners,crazy fast for the time. Whew....those were the days!
Wonderful video, you all know that Mercury was the god of speed right ? I had an alumacraft vee hull ,14 foot boat with an old white color 90 hp six cylinder Mercury on the back , it didn't have a neutral gear , yes that's right no neutral it was made that way crank it an go , the speedometer had 60 mph on it with a pin down below that which was the stop , that alumacraft would run so fast with the Merc on it that the speedometer would hit the peg past 60 mph and the water would come out of the overpressure relief on the back of the speedometer and run in the floor hitting your feet " that was the good old days !
@@pjimmbojimmbo1990 your wrong , very few people know this but Mercury made a vintage " Tower of Power " 6 cylinder outboard motor that was painted" Stark white , it was designed for offshore racing and did not have a neutral position , it only had forward and reverse ! We took the engine to a authorized Mercury outboard dealer only to discover that yes indeed it was a " long shaft 6 cylinder offshore racing engine ! The owners manual even said that you had to turn the engine off and shift into reverse then start it up to go backwards so you didn't damage the gears !
That boat was under 440lbs with the 60hp motor and a 8500 to 10,000 RPM max range on it and had a hull profile that was almost flat..... Most fishing boats that have a 60hp on it now weigh in at 800+ and have a 5000rpm max..
Two dislikes?? Who could dislike this video? I appreciate this video. Thank you. And i believe the other manufacturer was Johnson.. Maybe wizard back then.. Who knows... Lol
slightly slower because of the trim systems weight. on hydroplanes, the engine should never be trimmed. the nosecone of the gearcase needs to be more or less perfectly level for maximum efficiency. this isnt a pleasure craft.
what about what i said is bullshit? i've run v pad boats for 20+ years and have driven a few hydros. you are welcome to try to trim the motor of a hydro going 60+ mph... they are incredibly sensitive to trim. the last thing you want is the nose too light.
Kevin HeyMan You trim Tunnel boats and V bottom boats,not hydros.If you trim a hydro it forces the stern into the water and slows it down,and also makes it more prone to blowovers.I've raced and been almost killed in all 3,so I speak from experience.
"the first American outboard to go over 100 mph" because an Italian 4 stroke dual overhead cam outboard went much faster. Merc was not the world's fastest outboard.
