Re: prop
Howdy,
A 3.0L engine is usually about 130-140 HP.
There are prop shops that can tell you what you should (including Bayliner dealers)
The prop forum might be a good place to discuss the finer points.
You should prop the boat so that if the engine is running correctly, lightly loaded at the pressure altitude you will normally operate, the boat should reach the upper RPM of the recommended RPM range (out of your owners manual for that 3.0L engine) when pushed to wide open throttle. (If it's doing that now, you have the "right' prop")
Normally, for all around use, you'll get the best (all around) performance with a 3 blade prop.
