82 Starcraft MR 180 floor, slight refit and leaks

[redneck joe]

Welp, last time out I had water, used bilge a couple times but also had three kids getting in and out so was hopeful. About 35 miles of running yesterday just me and then wife same. Kills me that after 4 or 5 runs with maybe a cup full at the end of the day, this. All that work, two cans of gluvit.

Have you resealed the drain plug and any thru hulls below the water line? Any other equipment down there?

All re sealed when doing the refit and it collects while planing and all thru hull above waterline when on plane. I'm going to put some water in today. When I first started this the water would not drain out due to all the gunk under the floor now that it is all clean hoping I can identify the suspected rivets.

Filled the hull up to floor, found one rivet previously 'fixed' from the PO with jb weld. About on drip every couple three minutes. So since the current leak is significantly less that when I started this I'm hopeful that the on plane pressure is taking in more water than the few inches of water in the hull sitting on the trailer.

That said, any tips on the removal of the jb weld crap plug without damaging the actual hull and having to scab in a patch.

I can grap a pic if needed.

Wire cup wheel on a dremel. There are nylon ones for something less aggressive, but even the steel will be relatively gentle compared to a wire cup on a grinder.

Interwebs say jb weld will soften with heat and can be scraped. Anyone hear of that.

Not me. I used it successfully to patch holes in my old Sea Nymph and it remained unchanged for several years right up until I sold that boat.

I think that’s what was on a bunch of my rivets. I used a scraper, like a screw driver with a wide blade at the tip and a metal cap on the handle, like a cold chisel. Some came clean with a few moderate taps at the edges, some shaved into a smaller dome that was hard to chip. I ground them down with an orbital sander till I could see the rivet, drilled it and hammered it out- let it take the JB with it. Then wire wheeled or sanded the remainder. I will touch up with Alumahawk.
