5.0L Top Speed Test

[Halon]

We had some sweet conditions on Friday afternoon up in East Bethel. Decided to do a few top speed runs. Got one on video. We actually beat the speed we got on video by 1mph earlier. Was fun :)

Nice! What is the output of the engine?

[Halon]

It's a small block Chevy 305. More commonly referred to as the Mercruiser Carburated 5.0L in the marine world. Rated at 220hp I believe.

We also only have a 14.25 x 19p prop on there, which we purposely put on there for less top end but a better hole-shot (for pulling up skiers). We are reving it right to about 4800rpm there, which is about as high as these were meant to rev. With a higher pitched prop (21 or 23) we'd have passed 55mph for sure. Plus if we had less weight (less people, no coolers, etc), we'd be really cruisin !!

Thanks for the call, ass.

We woulda never broke 50 with you aboard!! ;) kidding kidding haha

Yeah 19 pitch prop is really small for that boat unless all you are doing is pulling skiers/wakeboarders; a 21 pitch would be perfect for that boat, you would not be happy with a 23 pitch unless you had only 2 people in the boat unloaded. If you want the best of both worlds, get a 21 pitch in a 4 or 5 blade. It will give you better stability and a better hole shot, you would get about 55mph out of it because at the speed a 4 or 5 blade creates drag.

But 50mph is plenty fast in a boat anyway. Oh yeah, and you should never be able to hit rev limiter in a boat in most cases, if you are you are proped way to low, because the prop is what limits your RPMS.

Nice! That's a pretty nice ride for that speed, was that on ottertail, or elsewhere? I love boats 'geared' low like that, the 19 prop is what I'd rock for sure. Pulling skiiers/tubers it all I'd do with a boat like that, dawn till dusk.

It was on Friday, about noon. We were on Coon Lake up in East Bethel. It was a little cloudy out, so there were minimal people out on the boat (little cloudy, plus most people work on a friday). So there were maybe 5 fishing boats out on the lake besides us. So it was so calm, perfect water conditions! Probably some of the best conditions we've gotten to enjoy all year! Did some skiing, wakeboarding, and some top speed trials. The boat ran so smoothly on the calm water, it was a blast!
