Drewb8 Posted September 2, 2019 Report Share Posted September 2, 2019 Im looking at my broken thru hull for the bilge and it seems like its inaccessible. The plumbing for the pump seems to run under the battery and from the opposite side of the thru hull there is no access, any ideas on how to do this?

Access was through a hole I had previously made in the battery compartment for installing lifting eyes on transom. Used a screw in 4” deck plate for recover. Had to remove hatch, battery and deck plate housing to get enough leverage to reach and work on it. Fitting was partially broken on outside of hull. Once I had my hand on the fitting a very small turn to left and right and the fitting fell apart. inside pic of old fitting. Outside pic Stainless replacement I used a stainless thru Hull fitting with a screw on composite 90 degree fitting setup as this looked as close to the original hole measurements and the cast stainless fittings that were out there made me believe I might have had to step drill out the original hole, which I was really trying to avoid. After removal of old fitting and excess sealant, there was more clearance than what I believed and the hole was maybe large enough for a cast stainless 90 degree fitting, but I’m happy with the result and notably the last time I should be worrying about it. Gem-lux cast stainless 90 degree fitting would be my first choice, if I had to do it again. Look at their website and determine if you have a large enough hole in the hull for one. If not, they also have the straight stainless thru hull and composite fitting that I used above. There are plastic/ composite thru hull fittings as as well, but I went with stainless as a hopefully one and done experience. for the access hole needed in the battery compartment, I went to my local Home Depot and bought a 4 1/2” hole saw and used a cordless drill. West marine had the deck plate. Here is pick of inside battery compartment I didn’t see the size of your boat, mine is an 18 and the access hole in the corner gave me enough reach to get to the inside of the hull. 1 Quote Link to comment Share on other sites More sharing options...
