hi welcome,
the max hp is on the, hull plate on the inner transom, i think an 85 was max.
but the uscg reues in the restoration forum, (at the top) have the calculations for max hp.
cheers
oops
Maybe only 75hp. Friend had similar years ago.
Thing is, the 85 probably a lot heavier...best I can guess at..
Yeah oops, I checked but everything is erase on that plate
