I assume he meant to increase the angle when he said add rake. I just know that Hydromotive and Mark were talking together about this boat specifically. Brett what is your professional opinion on what type of prop I should be using? I looked your website over and I see you guys sell the hydromotive products.

You need to find out what the timing is set at. Is it supposed to be locked or has the advance froze up???
If it is set 10* plus off from where it should be, you could be losing huge power. Its also not good for the engine and causes high EGT's if you run too little timing.

i assume it is locked since there are no springs or any thing in the distributor. I tried to free it up and it is locked without a doubt. What do you think the timing should be set at? I think it could be locked out and really advanced to make it idle better with that cam??? Is that possible?

Timing should be set at 32-36*

Ill check it out this weekend. I actually have a timing light i can set the degrees advance and then just line up the 0 mark on the harmonic balancer.

I have my timing locked out and I have no problems getting on plane. With the cam you have you will need to keep it locked to get it to idle. It really sounds to me like to cam timing is off. If your timing were retarded enough to affect top speed, with your cam it would affect idle also.

I have no problem getting on plane at all, it is unbelievable hole shot, faster than my 23ft crownline 454 w/bravo III

I installed the hydromotive prop with the re-work on it. I am running 66-67 MPH @ 5100 RPM. Speed does not change with 6 people or 2 people in the boat. Thinking i still need to run a little higher.

Until you find out if the engine timing is set up correctly, you're wasting time with swapping props. You might pick up 500-1000+ rpms if the timing is way off.

A guy I know couldn't get past 3200 rpms last Summer on a fresh rebuild. His timing was off about 15*+. Timing fixed and he was at 5000+ rpms.

Dart heads with 950 Holley and that big cam would give you peak power up around 6,000 rpm or probably higher ? Does it have a single plane intake as well? I Would say you are leaving plenty of power on the table by spinning only 4800-5000rpm. Smaller cam and dual plane intake should give you a ton more torque exactly where you need it........ TBF
