I have a '91 Evinrude V4 120 HP, great long lasting engine for me. In buying some parts for it, I have noticed that the V4 140 HP in these same years uses most of the same parts- pistons, crank, etc. etc. Does anyone know what the difference is between these two engines for the additional 20 HP? Is it purely carburetor jetting?
