Whats goin on here? Osprey 175

[amill411]

So I pulled the aluminum cap off the transom and this is what we have underneath. Not sure what to make of it.

Does it look okay/bad? Does it need to be re-glassed or can I get by with some 5200?

Transom feels rock solid.

Advice is appreciated.

Clean it up and fill in any voids with a two part epoxy. Slap a new piece of aluminum channel on it and let the four winds blow.

What year is that hull?

Oh yeah I forgot to add - the hull is a 1996

What you're seeing is the inner liner coming up and over the top of the transom. I agree with CB, clean it up with a small grinder, mix up some thickened epoxy, squeeze it into the gaps and cover it so you can't see it.  The epoxy will protect it.  This separation is very common on these boats since they make the hull, set the stringers in, foam the stringers and maybe elsewhere depending on the year, lay a bunch of bonding compound everywhere the liner will touch and lower the liner in.

Thanks for the info guys. I appreciate it.

Personally, I like to bed the aluminum in clear silicone after you clean up and fill the voids.  Keeps salt out and prevents crevice corrosion.  Get it right, and you will get a continuous bead of silicone around the perimeter.  You can either wipe it off, or don't touch it and let it cure and slice it off with a razor later.

This takes a little extra effort, but works very well in the long run, in my experience.
