    Gusher guessing; follow up-gctid825832

    I found the problem to the generator over heat. I closed the sea cock to the genset and removed the supply hose. Only seeping water could be seen dribbling out. I use the wooden stick plunge method and water came out. I was expecting a geyser.

    Here's the question - shouldn't the spout of water coming out of the sea cock be as high as the waterline?

    Only 1 1/2 inch above the hose nipple was coming out. The top of the hose nipple is approx. 10 inches below the waterline. I thought the water spout would be 10 inches.

    With no frictional loss, yes, but that never happens. Have you had a diver clean the intake grate on that thru hull lately?

    Most of these systems are way way oversized and will function with a lot of blockage... Going from seeping to 1.5" may indeed be your solve.

      Pick up a small triangular paint scraper or shave hook, throw on your tank and get under the boat and use the sharp points to ream out the accumulated paint on the openings.

      You should be fine. You would be amazed at how quickly several coats of bottom paint can close up a small opening.

        I almost bought an underwater drill to ream out the holes but the cost is close to haul out.
