1984 Sea Nymph Muskie transom repair, what is this stuff ?

Rot ro ... but while no wood rot, I'd bet $$ that was a saltwater boat and the untreated (as in not coated, and I do not mean PT wood) and the transom wood got wet. Add wetness, heat, and salt led to chloride precipitate corrosion on the boat in a really, really bad way.

If if were mine, I'll pull and replace the wood and would only use epoxy coated wood.

It looks like there's another spot brewing up above the handle.

wow - thats bad.
you really won't know anything until you get all the transom wood completely out.
and to err on the side of caution - remove all the paint on both sides of the transom metal.
then - ponder over your options:
depends on how much you like that boat.
how much time and effort are you willing to put into it.
what is the end result for the visual effect . . . look like new ???
also - if it is that bad on the starboard side - what will the port side look like ??
repairs can range from putting some HVAC aluminum foil tape over it to
pop-riveting (or solid rivets) a scab over it with the appropriate adhesive sealer (3M-5200) to
cutting out the cancer and weld in a new patch - grind smooth, prime and paint.
cutting out the cancer and epoxy some glass cloth over it on both sides - sand smooth, prime and paint.


if it is that bad on the starboard side - what will the port side look like ??

Thanks for your response also Johnny. It is contained to these areas and once it is back together I'll make a couple plates to cover the damage from the outside, maybe .100 thick or so. I'll do the two the same to somewhat match the shape of the transom so maybe it will look kind of look like they belong there, as much as possible anyway.
