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.
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
