I have a 19' 92 Bayliner capri with an I/O merc 3.0 and alpha 1, I think it has 135hp maybe I use it mainly for water sports like tubing and wakeboarding but do fish every once in a while. I have an aluminum 14x19 on there now but it takes forever to plane and pull me so I want to switch to a 4 prop but don't know what size to get can I please get some help. I cant remember what my rpms generally run. thanx ac

Ayuh,... With the total lack of Info, 'n based on this tiny tidbit,...

I'd guess you could Try a 4 blade 18" pitch prop....

You can probably get the prop fixed and get some real numbers then if a change is in order you can keep the prop for a spare.

The Solas Amita won't break the bank and we have had a lot of good reports on them.
You might first want to be sure the motor is in excellent tune,good compressioon and the throttle opens all the way.Someytimes the foam under the floor absorbs water and can add a couple of hundred pounds right at the stern where it hurts most.

I just went from a 21p 14.25 blade to a solas rubex 4 blade of the same pitch and gained 3 mph throughout the entire engine range. This is also on a 3.0L but my engine is 2010. Ditto with others with making sure your engine is shipshape first.
