Re: 37 AT Prop Test Results
Also spoke with Julie at Throttle UP and Pat with Active Thunder today.
Julie thinks that my prop slip is way to high with the 30 bravo's, she caculated it to be at 24% slip needs to be around 12-15%. She recommened a 1" spacer. A friend of mine has a pair that I can try before he uses them. FREE trial cant beat that. Getting the prop in the water a little more might relate into speed? we will see.
Pat said would not hurt too try but on his testing and building of the boat it is set up perfect, but anything is possible, so try away!!!
Will keep updated.

excursion: What did you do to your engines?
I suspect that your drives are really too low for the five blade so they have more blade area than you actually need. It would be interesting to see what a 28 Maximus would do.

Re: 37 AT Prop Test Results
Linster should be the one to tell this, he took time from his own motor project to rebuild both my motors and many hours porting heads & painting motor parts, I am indeed forever grateful to have such a great friend.
Motor Build UP:HP 500/510
Crane cam, SRP pistons 30over & raised compression to 9 3/4 to 1, Rollmaster twin timing chains, AED 850HO carbs, ported heads, port matched intake, everything balanced, all new cam bearings, Seal pro rings, Melling oil pumps, ARP rod bolts & recondition rods,MSD soft touch rev-limiter....
Think thats about it.
I am really happy with the way they have turned out ,look new and run better.
