Removing thru hull in 5 minutes.
Tools:
-electrical cord supply power
-dremel tool
-dremel tool diamond cutting wheel
-hammer
-screw driver
Procedure:
-install wheel on dremel and plug in
-insert the wheel about 3/4 of an inch up inside the thru hull from the outside of the boat. Turn it on and cut in a circle around the thru hull...you are cutting the shaft. This step takes about 1 minute.
-go inside the boat and tap the inside portion of the thru hull with hammer and it will fall away onto floor. (you will usually hear them fall over when you are still outside as your cut is complete) If you can see it you may tap the outer piece and it will fall to ground. If you can't do that go back outside and put the tip of the screwdriver in the hole and pry the outer piece off...easier than it sounds.
(total time up to now is about 5 minutes)
-clean area up from previous sealants etc.
-mix some epoxy resin and put some around the exposed edges of the fiberglass the entire thickness of the boat....this will seal the fiberglass and it rarely done during construction. Allow to dry (not necessary but a nice touch).
-install new thru hull.

PS ... I might have come up with that one when doing my thru hulls back in 2007. Strained my intercostal muscles (ribs) leaning down under forward tank pulling on wrench to change head and holding tank thru hulls. I never heard of anyone cutting them like that but they would go back in to a hole and try to cut it from the inside....I was already too sore for that. After a smoke, beer, withering around in spasms swearing I had to come up with a way to:
a) stay out of that spot
b) no more wrenching today
.... so, this little procedure popped into my tiny little mind. I don't know how many I've taken out down around the club...usually do a couple every spring.
