Chris

Chris, this is CCM, bought a Yamaha 90 hp from you back in 08. I just bought a KW 216 BR with a 225 Yamaha OX on it. In the console was a 21p Lazer SS prop. will this fit the Yamaha? and is this the right pitch I need for this bote. Thanks.

21 pitch seems kind of high for that rig, but im not sure what hub size the prop you have is.
put it on and run it, and see what your WOT rpms are

I agree with Chris… I would run what I had before I did anything else. If you do need to change it you may want to check the Yamaha web site to see if they have a performance bulletin for your rig? If they do it will have the prop information for their test on it. http://www.yamahaoutboards.com/owner-resources/performance-bulletins
