    Wrong Manual

    SEI Sterndrives

    the need for routine maintenance items does not mean the drives need to be rebuilt. new gimbal and bellows kits, alignment and gimbal installation tool, new water pump kits, new U-joints, new input shaft seals, cut the old prop off and new anodes and paint and you are in it for about a grand...

    Mercruiser 4.3 oil gauge mystery

    Pourable Transom?

    When I used seacast, I still had to undeck the boat, use a chain saw to remove the wood and still ended up cutting the inside transom skin to be able to clean up the fiberglass surface prior to pouring the seacast as stated above. there are no shortcuts.

    Starter starts something spinning in the back of engine only, nothing in the front.

    sounds like either your crank is busted or your flywheel studs are broke. either way, the motor is coming out and you have to investigate

    If water comes out of propeller it means thermostat opened and water pump working?

    The thermostat in a marine motor is used as a mixing valve. There is always water being pumped into the motor , the thermostat may or may not divert a small amount of water thru the motor,, however water is always flowing out the exhaust to keep it cool and from burning up your boat
