    Engine stalls when put in gearMy boat is a 1979 27 ft Carver Monterey Mercruiser 228 305 4barrel - Alpha Drive The engine stalls when shifting gear

    you are going to blow up your drive. replace your lower shift cable, adjust the cable correctly and get the RPM's down to below 650 in the water my guess is your thermostat and housing has an issue

    Volvo Penta 5.0 GL-B does not go properly

    do not stick anything metal in the passages other than maybe a piece of soft copper wire. the bowl, metering plate and throttle body are made of zinc and easily damaged. do not use simple green cleaner or bleach for the same reason.

    @achris if the ECM doesnt know its in gear, i believe the ECU limits the RPM to 3000. Am i correct? I believe this is why you stated look at the in-gear switch

    Waterproof seal on Nautolex clad surfaces

    butyl tape will make a seal, even if it doesnt stick to the nautolex. the top layer of the nautolex is designed so not much sticks to it.
