    1973 Gibson help

    The motor is not used on just Gibson houseboats. The pump may also have been replaced by another, so we also don't know. Unless there is some kind of serial number that can be looked up somewhere showing a parts brake down we have no where to look. Look at the motor and find the pump. The pump...

    First find out what model pump you have, then it should be easy enough to find parts or replacement.

    If that was a gas motor you would have blown a head gasket. That temp can also damage the diesel . Temps should not go above the thermostat setting, no more than 180 Replace the impeller

    2002 5,7 Mercruiser exhaust manifold keeps cracking - 5 times this summer

    What you have just makes no since as to why it's happening. If it was the manifold then why doesn't number 6 have same issue. The hoses are routed the same for both manifolds and in most all cases the port side does get a tad bit hotter the the starboard bank. Scott's idea may provide some...

    Onboard Battery Charger

    ^^agree I should have mentioned that just because it's flashing, might not be an actual problem with charging

    Welcome All boats have some sort raw water pump that moves water either thru the motor or thru the heat exchanger. Most likely yours has a belt or crankshaft driven water pump. In other forums I'm finding the Sherwood G7B pump used...

    Onboard Battery Charger

    Not 100%, could be either. Most likely it's the charger, but swapping leads can verify

    Should I redo the pink RV antifreeze that I already used last week to winterize Merc 5.0?

    From what I've read your good I wouldn't worry about the PS cooler, it's high on the rear of the motor and will drain automatically. A concern would be IF you have a Bravo outdrive, and if so drain the pump. You said Carb and 5 plugs (2 block, 2 exhaust) so is the other on the raw water pump?

    Onboard Battery Charger

    Don't know which it is so looking at the 10A 2 bank manual, it could be the charger or the Battery. Swap the leads between the Bats and see if it starts flashing on the other one Manual

    2006 Monterey Boat with a 4.3L Mercruiser TKS Engine S/N 0w354897 Mysterious Loss of Power

    As mentioned before, run until the problem starts or at least long enough to be able to start and create a vacuum (if this is the issue). Stop boat, get your ear close to gas cap and open it, do you hear air being sucked in? That's about it

    Volvo Penta 3.0 Beeping and Ggoing Into Limp Mode

    Don't know which code number, but you did say sensor reads 198. If a sensor thinks the something is overheating, it will limit rpm to try and save the motor. This can be a brand new but defective sensor. Can be a bad connection to the sensor, in correct voltage applied to sensors. The scanner...
