    High RPM, little or no acceleration

    Early 1960s Evinrude 75hp Starflite Barn find - Worth it?

    Possibly another cobbled together motor, from various parts. There is the possibility of someone going berserk with a spray bomb as well. A 50 and 60 would have cylinder heads like these

    Are Boston Whalers as prone to waterlogging as other boats?

    Put a very strong Shop Vacuum over the Holes with a good seal, and let it run for a few days, maybe weeks, that might remove the water from the foam

    Early 1960s Evinrude 75hp Starflite Barn find - Worth it?

    That colour looks like from the late 50s, but wasn't Johnson painting its engines white by 58? I guess they did make a 58 50 in that colour, So this might not even be a 75hp, but a 50 under a 75 cowl Edit: the Heads look like the ones used on the 89.5 block, not the 70.7 block

    Are Boston Whalers as prone to waterlogging as other boats?

    Complete foaming of the Hull to the Deck has been happening for over 60 yrs. OMC was doing to their boats back in the early 60s, and I doubt they were the first

    Regular fuel

    It won't run any better, in fact it will actually make a tiny bit less power on high test.

    1985 evinrude 30 hp prop power issue

    Either the hub is bad, or the prop is ingesting a lot of Air/Exhaust. Does the gearcase housing have any damage in front of the prop?
