Normally I can hit 50 on a good day.

I change the prop from 25', 3 blade to a 24 pitch, 4 blade. Last weekend I open it up to check the speed. I am alone and I have a full tank of gas. I am spinning 4400 rpm. Same as the old wheel. Using the VDO speedomenter it was registering 55 mph. Fastest I have ever been on this boat. Looks like I decrease the slippage going to a 4 blade. I always check the gph of my boat by writing done the hours on the hour meter every time I gas up. I'm surprise last weekend I am using less gas. A liitle less than a gallon per hour than average. This is only one weekend.
