...........Puzzled
 

29 kryptonite 620hp JCperformance power. Ran the boat in October with a Bravo 1 30p double labbed by mercury. This prop also had the cup taken out of it. Boat ran 89mph and turned 5700rpm. Ran a labbed 30 Bravo 1 in May and ran 83mph turning 5200rpm. Today I ran a stock 28 Bravo 1 and only turned 5000rpm and ran 79mph one way and 80mph the other. The engine can turn up to 6500rpm but in reality I only want to run 6200rpm. Not sure where to go from here. I thought the 28 would have turned 5500 easily. Where do I go from here???:angry-smiley-038:

I would start by checking timing.

The stock 28 B1 should have run in the mid 5000's

Hey Brett,
I called you on Tuesday, actually spoke to brad. We decided to test the 26p and 24p B1's. Ended up you were out of 26's so he only sent a 24. We're going to see what kind of rpms that gets us and then buy it, double lab and remove the diffuser. The goal is 5900-6200rpms.

I'm lucky to have Brad in the office (among other hats he wears). He has given me some breathing room. He knows his stuff and can take the regins when I get overwhelmed.

Thank you,

Brett
