    Default Raw water pump

    My boat came with no water pump as it was removed, buying new would cost me 500 if I add another 700 I could get a new engine! The question is, I got two jabsco water pumps which can pump more water through than the original pump can! Bit I made adapter to make sure my pumps are working and pumping, bit they pump through more water than original should, can this cause any problem to my engine ? Only people who understand are welcome to reply! Pls no guesses! Thanks

    The problem might be that the engine is running at too low a temperature, and that leads to poor combustion and wear.

    Are you pumping sea water with pumps designed for fresh ? I am not sure that Jabsco FW pumps are designed for continuous operation e.g. for an hour or two.

    What make and model is the engine please ?
    I think, therefore I am. I am, therefore I sail.

    Oddly enough a ‘different’ poster did just that yesterday.
