i have a 1979 evinrude 115 that i rebuilt last year running good about 50 hours on it now. i have heard that the only difference between 115 and 140 is carbs and the bubble back exhaust. was wondering if anyone has done this and what years i can cross over from my 1979.
try over on scream an fly forum they more on that stuff,if you dont get what ya want here,OH welcome to bass boat central

i have a set of those bubble back exhaust
Dont even mess with it. Blocks are different(plus other differences). By just bolting on the bubble will not make 140 hp. leave the 115 alone, just gonna wind up with a bunch of problems.

thats correct one is a cross flow the other is a looper completely different blocks dont even try it all you will get is a headache
we use to bolt on the buble exhaust and the deflectors, change carbs and install a set of land & sea heads ............I still have a set of heads and 150 carbs

Did you experience any real significant increase in horse power?
If you can't run with the big dogs, just stay on the porch.
