Re: 1984 gamefisher 7.5 replace
I think what he is saying is he wants to change the powerhead.
IMO don't bother.Your just flogging an inferior setup.
Put your time and effort into a 3,4,5,5.5 or 6 hp Evinrude or Johnson
from the early 50s to the late 70s.More reliable,faster,smoother,quieter.
Routine parts available from dozens of venders and any well established BRP dealer.
