Pix please for clarity, eh?
that hinge pin area is at W/L, I have not payed a load of attention to mine. I have these old pix of a 77 25'er butchered out. I think I have more extensive pix at home, lemme look, I've had that apart but no repairs mod's required.
Dropping the C/B is easy, putting it back in and alligning it mo' difficult. On the bright side you can examine and paint the trunk and the 300# board.
I'd like to see that in a digital pix. I have an entrapment area alongside the trunk an inside the locker, when swamped it retains water after the hull is drained. I'd go slowly forward, since if you have delam' only at the 4 screw holes, you may hear the whizzing sound as you dodge a bullet.
Trying to keep it only partially submerged is like a brotherhood.
