    Does 1963 350, 35HP Mercury have a tell tale/pee hole?

    I will hook the engine up to muffs or submerge the lower unit in a tank and will get the same results. A small amount of water will be discharged from the top of the driveshaft house/ below the engine housing but nothing significant. Its on the Port side. It appears at idle that only a trickle...

    1963 Merc 350/450/500 lower unit rebuild

    Anybody here have experience rebuilding one of these? I have the factory manual and it seems pretty basic. No real speciality tools are required except for the shift shaft bushing removal tool (which isn't really required) and the gear cover tool which i'm having a hard time finding. I will be...

    Prop selection for 1963 Mercury 350 35HP (high altitude/low Altitude Application)

    I think sportsman is the model name. Next time i'm with the boat i'll try to grab more information from it, although i don't remember finding anything else. i would agree that a 50 HP would be really nice for this boat. I will see how an 11" performs with this bad boy and go from there. I just...

    Prop selection for 1963 Mercury 350 35HP (high altitude/low Altitude Application)

    I may have read the wrong gear ratio. I forgot the lower unit i'm receiving was reported to be pulled from a Merc 500 which was also shared with a merc 350(4 cylinder)? See attached screenshot from my service manual. I won't know until I actually measure it physically but I can safely assume the...

I am able to find these props for this boat (ebay) Used and new in various...
