I just had a new engine installed on my boat, a rebuilt 93 Evinrude 50hp. Right now I'm running a double oil/gas mixture (25:1) in order to help break it in, as per the installer's instructions. What I want to know is if I'll gain anymore top end speed when I switch back to a 50:1 mixture? The reason I ask is this engine doesn't seem as fast as my old engine, an '89 Force 50hp. The marina even said this engine was bored over slightly so should have a little more than 50 pony's. Any input?
