Great looking boat, what the hull like on these boats? Deadrise? Pad? Notched Transon? Steps?

Don't quote me but I believe the deadrise is 22*, Delta pad, I think I know what you mean by "notched transom" yes, no steps......rock solid ride, not sure how true it is but tole Kevlar or partial Kevlar hull and composite stringers......I will sell this for a song, health issues.............:daz:

What is the top speed anyone has been able to get out of the hull. I have had my 502 worked and the best I can get it 82. I can turn a 29 pitch prop at 5000 RPM and dont get anymore speed than turning a 25 pitch prop at the same RPM. Any suggestions.

What is your drive gear ratio? 1.36?

Where does your rev limiter kick in?

Not sure on the drive ratio. He was supposed to set the rev limiter to 6000. It doesn't sound like I am hitting it though.

Assuming the 2 props you mentioned are the same type, it is very difficult to figure why you would run out of steam at 5000 rpm with each unless it was something mechanical. If you have the HP to turn the 29 to 5000 you should be turning the 25 to well into the mid to high 5000s.

Drive ratio is critical for helping to determine a prop. For instance, if you are really turning a 25 to 5000 rpm and achieving a speed of 82, you must have a 1.36 drive ratio as with a 1.5 at that pich and rpm you would only be able to run in the mid to low 70s

It doesn't make sense to me either. The 82 is under perfect conditions, 1 foot chop half a tank of fuel and no passengers cool day. Probably was hitting 5100 to 5200 RPM. I have tried 27 29 and even a four blade 32. Every prop got me around 5100 except the 32. Best I could get was 4800 out of it. Out of all of them the GPS stayed in the high 70's to low 80's.
