What speed is the torqmaster lower unit on a 300R 4stroke capable of before blowout will become a concern? Boat is a triton 21 bass boat about 1.25 below pad frequently touching 90 MPH. I have another prop that is capable of a couple more MPH but don't wan't to risk a blow out so I haven't pushed it. I am worried there would be a substantial performance loss running a heavy boat like this with the new bigger sportsmaster gearcase.
