Re: Prop experts ideas
I haven't had it on the dyno yet just got the boat.
It is a 502 block.
All custom made. 850 holley,edelbroack square intakes, aluminum crane roller rockers, alm. covers and CMI elbow exhaust. I am estimating the 470 could be more or LESS! I wasa told it has a stock 502 cam?????

Re: Prop experts ideas
Your engine configuration tells us your more than likely low on your current WOT. If you can't get the exact dyno sheet, I would prop the boat in the low 5000's.
Lab Finishing your current propeller will get you there.

Re: Prop experts ideas
I met a guy two weekends ago with a 1994 29 with a 502/502 GM crate motor that ran 67 on the GPS if that helps(so he said). I was under the impression that a single engine 29 scarab would run 64-65 stock. Something does not seem right in your numbers. I wounder if the tac is right. Also are these fully trimmed numbers? Mine requires a ton of trim for top speed but I also have twin 350's.
