Hi there, we now have possession of our new to us 2015 RT 31CB. As we work through a bunch of maintenance items, I am wondering if anyone has a source/recommendation to replace the gasket sealing the propane locker located on the swim platform. I'm hoping by keeping the salt water our a bit more, our new tanks will last a few years. Many thanks.

I did try searching, but couldn't find a topic about this.
 
My gasket is a mess and I cannot find a source either.
Have you had any luck since posting this message?

My propane locker fills up with about a quarter inch of salt water whenever i run the boat. The boat is 2 years old, and the propane tanks are already extremely rusted. I asked the RT guys about it, and apparently there is a drain hole in the bottom, which seems like a strange design choice. The locker only fills up because of the drain hole. Has anyone tried sealing up this drain hole? It seems like it should be possible to keep the propane locker completely dry.
 
I sprayed both my propane tanks with Flexseal which rubberized the exterior. Not the perfect solution for the keeping the water out of the locker but at least the tanks aren't rusting.

Please do not seal the drain holes in your propane locker. It is there to drain the propane gas if there is a leak. Propane is heavier than air and will drain out the hole the bottom. If you seal it it could become a fire hazard. It is an ABYC standard

I coated our propane tank bottoms with truck bed liner paint.

Andrew Custus sent me a source for a new locker gasket. it was $75 on Amazon for 25 lf of gasket. The gasket on my locker is 3 lf long.
I bought an industrial adhesive that I hope will rebond the plastic cap strip to the rubber gasket. I glued it tonight and will cruise to Coupeville Thursday.
Stay tuned.
 
Jeffery,
I thought 90 bucks for the three feet of gasket I needed was a big hit.
I went to a speciality rubber company in SODO and bought an industrial adhesive sealant and glued the bulb to the seating flange yesterday. $6. Renegade will get wet Thursday. I will report on the performance late next week.
Curious note.... the seating flange is plastic or vinyl and the gasket itself is rubber. In my case the two delaminated and just needed to be joined again.
