I ordered a 32 pitch 15.25 Maximus prop today with a shortened diffuser ring. I'll post the performance data as soon as the boat is back together.

Have you tried to increase the negative trim. It worked on my 26 Daytona. I shortened the trim ram inner rods 3/4 inch and with a little cutting and grinding I got the drive to go down equal to 3/4 inch shorter rams. The boat wouldn't even try to get on plane with a 28 pitch 4 blade bravo prop. After I Tinkered with the negative trim it hops up on plane with the 4 blade.

I tried a stock 26 Maximus and it made the boat ill handling.

Thanks for the info Tinkerer. We took the boat out yesterday and tried a 32 Maximus and 32 Bravo 4 blade. It seemed to like the Bravo 4 blade better. Planing wasn't an issue which is interesting. We're going back out this morning because it was too rough from all of the boat traffic to dial in the fuel air ratio at higher speeds.

Eddie tuning the carb on the 4th of July. We're going back out this morning to dial in A/F ratio. Eddie Young is the real deal!
