Replacing transom foam seal

[jonny rotten]

Getting a new/used transom assembly. 1995. If the foam seems to be in good shape should I leave it? Does it bounce back when removed and recompress correctly or is it a one and done part. Hearing its glued in and a PITA to remove. If I need to remove it any pointers to make it easier? Someone mentioned acetone

Make sure transom is not rotten!!!!! I added 5200 to help seal and also to hold seal in place as I installed assembly onto boat. I also added plumber's foam inside to the lower cavity where trim cables pass. It will be a real pain to replace cables, if needed, but until you have rebuilt a transom on an I/O you will not appreciate this added precaution against leakage. Trust me!!

Best to replace it while it’s apart. Why take a chance on leaking and rot?

I would NEVER put any type of glues on any removable surfaces. You may need to reopen the surface again. Large areas to seal ???? Have unbelievable areas that will not separate easily !! Screwed up 1 time with a 4200 type of sealant. A horrible time with electric heaters and 3 of us.

weatherstrip adhesive to hold it in place on the housing thats all

The motor is out so it's an empty cavity. I was thinking about replacing the trim hoses. They look fine but I assume they are as old as the boat (25 years) With the motor out I would think it would be easy to do to just slide them out?? Do trim hoses pretty much last forever

What about getting them off if they are in with adhesive? Don't want to scrap the housing with a tool and obviously want the housing perfectly clean/smooth without foam remnants

Ayuh,...... Scrape it off with a plastic putty knife,.....

3M Adhesive Remover is great for removing sticky residue.

I’d never reuse that foam gasket, either. Why risk all that work to save a few bucks?

“Easy” and “trim hoses” doesn’t belong in the same sentence! Proper line wrenches and maybe judicious use of heat will likely be needed. If the rubber is cracked then yes have at it but if not, leave ‘em!

I'm a getting a new/used assembly that has a trim manifold on it. My plan was to use that trim manifold and put my lines onto it. Mine looks kinda crusty. Are you saying to unbolt the manifold from mine, don't disconnect any lines, and mount it on the new assembly? The new one has no lines attached to the manifold. I could just buy new lines and screw them into the new manifold and then I know I have new OEM parts. Probably going to run me over $300 for new stainless lines and trim hoses. Not cheap but with the motor out I figured now would be the time?

Ayuh,..... If yer lines are Ok, 'n you can screw 'em outa the manifold, there's on reason not to reuse 'em,.....

Agreed if they’re good no reason to replace

I'd also drill a few 1/4" holes around near transom assembly (inside) and near drain. Pray no rot, crap or water comes out. If so, now would be time to replace transom. You can put 5200 back in holes.
