Its time for a new motor. 20 or 25. I've been through 2 two stroke Mercury 20s which were completely badass, and most recently, a 2 stroke Evinrude 25 that has been OK, but is now worn out. A little on-line shopping shows that Evinrudes and Yamahas run about the same price. The Mercuries run a good bit cheaper. Are the current Mercuries WAS? Any opinions would be appreciated.
