I would try anything I could get my hands on, just stay with the same # of blades, if the problem is still there, then you know something else is causing the problem, if it goes away, its the props.

When I first got my boat I could not get on plane in anything over 1.5' waves. Took my props to the local shop and they said that over time all of my cupping had been washed out. They reblanced, trued the pitch back up and added cupping. I lost 150 and 1mph but I now can get on plane in any type of water.

Hello I was wondering if the boat has drive showers on it, because I have heard someone say that different drive showers where causing cavitation proplems. That when they take off the water flowing across the bottom would actually suck air from he top causing this. Just something I heard dont know this for a fact.

Something else weird on my boat is both drives/props spin the same direction. Could this have anything to do with it? It sucks as the prop torque get pretty bad when backing off the throttles, wants to make a hard right especially if throttleing down fast. On a good not it gives me a good reason not to let anyone else drive my boat!

Vent holes are in the front of some props, at the base where the prop meets the drive. These are plugged with a plastic cap and can be removed to allow the prop to aerate so it can spin a little easier on some boat. The diffuser ring is the flare at the back of the prop, this ring is used to keep exhaust gases out of the blades so you do not cavitate in the exhaust.

No, twin Bravo 1's. I'll run up to the storage real quick and take a look at them. Its also straight thru hull exhaust, no captains call etc... so no exhaust runs through the drive/prop what so ever.
