I have a 2007 bass cat phelix with a 25 hp 4 stroke merc. Boat is 530 lbs dry, 17 ft long and 42 inches at the waterline. I have a fixed jackplate installed and the cavitation plate is about 2" higher than the bottom of the transom. My current prop is an aluminum black max 9.5p i had a 13 p aluminum prop on before and it was too much the boat would only run about 20mph. With the 9.5 i run about 26 solo and dont hit the rev limiter. Any suggestions?

You might want to say what your objectives are.  Speed? Load? Hole shot? Etc.
Also give you WOT RPMs.
The guys that know props here will be able to help you better that way.

I dont currently have a tach, but im working getting one. In turns or with heavy loads the prop ventilates bad and blows out. I have to stop and restart. I would like better overall performance. 9.5p seems low compared to other peoples setups.

first thing to get is a tach, even the pros like prop gods and powertech will need to know what rpms you are running, then at that point provide you with a few suggestions for different props

With 2" above the bottom of the hull you motor would need an 8" setback. I'd start by lowering the jack plate an inch.
