A stock HP500 probably won't hit 70... I wouldn't build a 500 replica, either. Merc left a lot on the table, power wise, and I don't like the combo they used. A big block with rectangle port heads and a single plane intake manifold that is only rated at 500hp can only mean 1 of 2 things. Either they won't let it wind out, and you get no intake velocity, hence the low hp number, or they were limited by the exhaust and used an insufficient cam and it can't wind out and make any power.

Decide now if you want wet or dry exhaust. If wet, brand and model have a lot to do with how much cam you can run and how it's timed. The cam will dictate how much static compression you can run... (To a point, unless you want to push the edge, then a lot comes into play)

Damn, It takes a LOT to get one of those going. You must really have to love a boat like that to dump money into a motor. Ive never had one but it seems you could get a 25'+ boat of another brand to run in the mid 80's with what it takes to get that thing to break 60... I may be inclined to reconsider which boat I was running

Yeah, they are not light fast boats by any means. But, they ride good, are built good, and who doesn't like a sleeper? Winter plans for mine are: extension box, xr upper, imco -2 lower, k-planes, hydraulic steering, 30p bravo 1. My build wasn't too exotic, I could have went way way further. Once I get done beating this hull into the ground, I'll buy a fast hull with no rigging and transfer it all.

Yep , as soon as the lake is anything but flat you feel like your nuts are bouncing off the floor . Rode in friends 225 Crown with a Procharged 454 Mag EFI , 1" Imco shorty and labbed B1 many times . Nice little sleeper though ! Before the 1" shorty that thing would like to snap your neck from the chine walk and felt like it was trying to screw itself into the lake !

Haven't had an issue with mine. When it gets rough, I trim down to drop the nose and does fine. If you leave it trimmed up you'll end up airborne.
