I have a 1985 60Hp Evinrude and am planning on doing some modifications over the winter to get me to my desired speed. I've read some articles on here recently about sending the flywheel off and having milled to gain a little bit of speed. I'm new to the word of outboard modification so I don't fully understand everything yet. I was wondering, is it a good choice to get it milled, or am I just asking for trouble in the future with reliability? If it is a good option, are there any specifications that I should stay inside to make sure it will work properly? Dimensions or weight reductions? Any comments or replies appreciated.

Thanks, Cal
