RE: Abandoning a Thru Hull
AllFor what it's worth, I removed a two inch thru hull eight years ago that led to a keel cooler. At the advice of the fellow installing my new engine, we did as a couple of you mentioned, and ground a taper into the hull that extended six inches out on all sides, both inside and out. This took us down to only about a half inch thick hole and about an inch of new glass depth in the middle. I check these patches from the inside any time I am in the engine room. I also look it over when hauled out. In all this time I have seen no sign of any movement, separation, etc. I believe, know what I do about fiberglass that it's as strong as the original.
