Max 5 is suppose to be great but at 2200 each I'll give up a little with the Bravos. I'm running the HD case but not a sportsmaster. No need at my speed

300R prop issues
I hab
I have a new 22’ Chaudron, I only have 3.1 hours onn the engine, I have tried 2 props and I am thinking something is off… started with a Bravo 15.25x32, ran high speed pretty good, had a lot of porpoise without speed, engine height did’nt seem to make a huge differance neither did trim. So I put a FX 15.25x30 on, did some measurements and marks on hull, lower unit and gages. Boat woild not plane with 4 people in it but with just 2 it seemed to run pretty good…about 89mph without pushing things. The FS cavitated hard when trying to come up. Feels like too much prop, but not sure it should be with a 300?
