Go to marinepartdepot.com - the second one down on the left that showed up when I just went on, the LOCKABLE HOLD DOWN CLAMP looks a LOT like the hold down on mine. There is one clamp in the middle at the top. I’m not wild about that latch - you have to hold it up while lowering the cover (kind of awkward). It works, but you may find one that works easier.

Mine doesn’t have any sound insulation any more either (I scraped out the last crumbling bits early on) - I think you can find that stuff (probably better than the original stuff) online, cut it to shape and glue it in.

The aluminum strip you’re talking about, mounted to the transom wall, is a gutter rail to divert water from dropping onto the motor when it splashes onto the cover. I had to add a few screws to mine to secure it to the wall so the water didn’t just run down behind it.

Mine has no seals around the bottom and I don’t think there ever were any. My scuppers dump into the bilge to be cleared by the bilge pump, and any water getting in under the engine cover is evacuated the same way. There are wood strips on each side of the cover, screwed to the deck, which hold the cover in position when someone leans on it. On mine they were too loose a fit and the cover was occasionally pushed out of the hinges - not a good thing, so I added some blocks on the deck, inside the cover to hold it in place better. That cover gets leand against plenty landing fish.

Please let me know if you come up with a good sound insulation resource. My boat is gathering dust right now, due to some other urgent things going on (and the fact that fishing in the Columbia river has been lousy for the past few years).

Good luck with the boat.
