Been eye-balling 'em every time I walk around doing all the repair projects wondering if I should take them apart for a look-see. Finally did last night and it's a good thing. These are the rubber flap jobs with the white plastic flange and 4-screws holding them it. Piss-poor design if you ask me...too many parts, prone to failure. The drain is white plastic 2-piece male/female fit. The female ID is barbed and installed from the outside. The male piece, installed from the motor well side, is barbed to self tighten when you apply pressure from both sides. I could write another paragraph about how the outside flap and flange and flap are sealed; but in a nut shell the fate of your nads are in how good 3-rubber gaskets seal to stop water ingress. In my case, the first gasket against the transom was dry rotted on the ID hence bad seal between the plastic drain and hull. I cleaned the gaskets, silconed them together and sealed aroung the outside of plastic drain with silicon. Checked this morning and it looked like everything was sealed. They're coming out next year. Think I'm going to use the bronze swedge installed scuppers like I had on my Escape. Wondering why Grady just didn't use those in the first place, any ideas? Is there a better design that the factory crap I have now?
You guys that want to repower your old Gradys with 4-strokes better check to see where your scuppers will be. The ones on my boat are not designed to be under water.
