Can a 1960 evinrude 5.5 hp be converted to a 7.5 by simply changing the carb. I bought what I was told was a 5.5, but before paying the seller he told me about the mod. I still bought it because it ran good, and he threw in a new gas tank.

Seems like every seller has a simple, cheap mod. to boost horsepower by 25%. Interesting how THEY never do the simple, cheap modification but are always eager to see the buyer do it.:cool: Don't tell me, all you have to do is change the carb. jets and grind out the opening in the intake a little wider.........:rolleyes:
Still, the 5.5 is a super motor.:)
Happy boating,
