Your already on a fine pitch prop so I'm guessing it's a big heavy boat?
So should I just stick with a Bravo 1? I'm sure it will handle 300hp.
It is a big cruiser. It had a 16x16 on it. I put the 13 on there to help it get out of the water. I suspect a bearing issue in the drive is generating the extra heat that is causing this issue. It may be that the 16x16 was fine and the low WOT RPM was caused by drag inside the drive due to whatever bearing is failing.
I have read it is advantageous to run a larger diameter prop on a cruiser but I am not very knowledgeable about this. I'm a car guy with pretty good mechanic skills but this boat stuff is new to me.
