Transom cap
 

I just finished my transom job. MY question is do I have to put a cap on it and if so what do I use? The transom isa 2-1/4" thick.

yes cap and seal it good

Isn't it possible to just fiberglass over and leave the cap off? It seems to look a lot cleaner when done this way.

The cap is a protector. If the transom glass should develop a crack from the bouncing and flexing it gets the cap still keeps the water out, and it serves as a protector to a limited degree for things being dropped on the top of the transom.. Plus a clean topcap looks nice also... Since things cost money, and lots of things cost lots of money, I've found that if a manufacturer spends money to install something there's usually a reason for it.

Yeah Curapa I put three layers of glass and plenty of resin on the top of transom already, I was thinking the same as you but it does make sense what destroyer is saying. I just don't know where to get it made so it will fit my thickness?

Look around online or in your phone book for a local sheetmetal shop. Pay them a visit in person late in the day when everyone is in a good mood with your dimensions...they'll probably bend you one up while you wait and charge you maybe $20 bucks...Not sure where you are located but if you are in NJ send me a pm and I can get you something.

You can also use vinyl siding corner piece. When i did mine, i wrapped it with glass and paint it different color so looks like a cap but fully waterproof.

Yeah when i said needs cap that means you need something on top to seal it up. i usually use 4 layers of glass over all mine.

Great idea! It looks fantastic, is waterproof, and won't corrode!

I glassed mine completly on the 18 and LOVE it. I highly reccomend it for a one time fix and clean look.
