Mariner 40 power increase ?
Hi, I have a mariner 40 twin/ twin carb early nineties(I think) 2 stroke
S/s... I'm not a boy racer, I did however wonder if there are any simple restricting factors that can be removed .. Would just like a bit more power from it as a heavier 50hp engine is out of the question ... Is there anyone here in the know?
I'm sure as these are a very common engine some people on here may have some info? Thanks in advance . :-) Jim
