Installing Seadoo Depth Finder - Which Epoxy?
I know that Seadoo recommends 3M-05895. This is a flexible repair epoxy. I went to the 3M site and they have a great marine adhesive sealant product selector system. It recommends good old 5200 for a fiberglass to plastic mating surface condition. 5200 also has the highest tensile strength. The only force I can see due to installation would be the pressure from the silicon disks and the top heavy transducer.
Has anyone used 5200 to adhere the bottom flange with success?

I used 3m 4200 on my boat transponder,and it worked fine. If you ever need to remove it(for whatever reason),I wouldn't use 5200.

Yea, 3M doesn't recommend 4200 for that application. I think I had better stick with their product selector. I have used 4200 in a lot of places on a boat, but most of them were fastened, versus simply glued.

Use any good (Devcon) 30 minute epoxy. Clean well with alcohol or laquer thinner. Rough up the surface of the puck and hull. Glue and wait 24 hours. Mine has held for 1 year so far.

Thanks Larry. In this case you are not gluing the puck, you are gluing a support ring that the puck installs into. So there is no epoxy under the puck. Just a clean inner fiberglass hull. I guess any slow - set epoxy would work. I reposted this because I have some 5200 in the garage and it seems to be what 3M recommends. I just can't get it below the puck - you have pointed this out in several historical threads.
I just don't want to pull the muffler out again. Thought I would check the brain trust first!!

Yea, the hardest part of the job was getting the clamp off of the 4-Tec exhaust. Nut came off easy, but the clamp wouldn't release. Here is a tip for all that might read - I put a heat gun on the clamp for about 2 mins and it fell off. You wouldn't believe the locktite under the clamp. Wow!

A slow set epoxy works best as it sets with less air bubbles in it vs. fast set epoxy. You can't use anything with silicone in it as the sonar can't shoot through the silicone. I used an epoxy repair type packet from West Marine that cost around $14.

my memory must really be bad, I installed a depth finder on my brother's GTX and do not remember removing anything from the exhaust. oh well......
anyway, I do remember using PC-11 marine epoxy on the transducer ring and it was cured enough by the time I finished the wiring to install the transducer.
