Any one have this problem with Hydromotive P5
I purchased 2, P5 5 blade 28 pitch 15 ½ diameter props from Hydromotive and gained 6 MPH on the top end so far and I know there is more if I get more seat time. My boat is a 28 Eliminator Daytona Cat, Twin HP 500’s Top Speed So far 100 at 5050 RPM. Past top speed with Bravo 4 blade 30 pitch 15 ½ diameter props 94 MPH. Drive gear ratio 1:32 Here is my Problem. The boat has a problem getting on plane. The props blow out and the engines rev and the boat cant get on plane with 3 people on board. My 2 passengers had to go up in the cabin to get on plane & with 2 people in the boat I can get it on plane with some real gentle throttle work. I would have thought that 5 blades would get better grip so to speak than 4 blades? Any Suggestions would be greatly appreciated !

Thanks for your Input Julie. They do have diffuser rings on them but after explaining my problem to Hydromotive a gentleman named Tom had suggested I send them back to have a larger diffuser ring installed & that might be my next move.
