Could eny one tell me what size of prop i could go up to on a 2002 90hp honda outboard? The engine is on a Shetland 535 boat. At the moment the prop is a 13.75 x 13 and the engine is reving to 6400!
 
I thought someone would jump in that has a boat like yours.

You may be hitting the edge of the rev limiter, so it may be difficult to hit the right size right away. In general a 15 pitch prop should lower the rpms 200 - 300 rpm. Maybe a little less. A 17 pitch will lower it another 200 or so.

If you can get it somewhere on the high side of 5500 rpm to 6000 rpm, that will probably be the most optimum prop.
