3 cyl Merc 40

[HGipson]

Yeah I'm one of the happy owners! The 19 degree crank right up makes it even better. Hopefully it gets colder and I can stretch it out some more after those ducks!

Well I got 3.8 hrs on her now. If I could get someone to come with me I would take a video to post up! Gonna try to make that happen over the holiday. She's runnin good but I still Havnt stretched out any of my speed props. Gotta warm up to her. Ran my 16p 54mph today, might coulda got a little more out of it but it's prolly a little soon to run it that hard. Took off my bobs sb4 and put the sb6 on it. Setup I believe is finally about rightAttachment 55711

Wow that's good for a 16p! What gear ratio? What exactly have you got done to your motor?

[Cajun Special]

Ported, cylinders honed, new pistons etc, flywheel substantially lightened. 60 carbs with .62 jets. Garrett turbo. Just kiddin. Block stuffed. You or anyone know if velocity stacks worth foolin with? Oh 1.83 ratio. Prop is a Ron hill 11.25x16 semi signature. That one and the signature 18p are AWESOME propellers. rocket fans is what I call them

That's sweet! Mine is ported polished, timing advanced, 40 single carb, 40 reed cage, reeds cage drilled bigger, leg and foot sharpened razor sharp used with a 18p Merc chopper 2! 58.7 mph on gps! My motor is the same motor as the triples but with one cylinder chopped off! Twin with single carb! I am buying the 60 carbs this winter and putting them on! I would definatly put stacks on and try it, when I remove the cab of my motor I gain a mph or 2! Have you or anyone here heard of the raised pistons you can get for these motors?

I've heard of those pistons but don't know anything about em. I put mercury pistons in mine. 125psi compression in all 3. U know anywhere in the US where they make stacks? Talked to a guy yesterday in austrailia that makes them. They look real good. Don't cost much

I don't! I'm from up in canada and that stuff is pretty limited up here! Wonder how much gain they give you? Did hydrotec do your motor work?
