[QUOTE="bassboy1, post: 86379, member: 55"] I had a Grumman 1256 one time, that was made in 1997, back when Lowe, Sea Nymph and Grumman were owned by OMC. It was the exact same design as the Lowe Series from both then and today, and it had pressure treated ply on the transom. If yours also has pressure treated wood, it could be the dissimilar metals (most pressure treated ply is copper impregnated, and copper and aluminum are dissimilar) corroding. What yours may be is that being that you boat in saltwater (which will speed up any form of corrosion), the ply is corroding the aluminum from the inside out, and those are the only spots that it has broken through.
