How do I seal the cap to the hull?

[MAtkins]

I've got a 17.5' bass boat that I had to replace the transom on.

The cap is on the boat but I've still got to screw or rivet the backend of it to the hull.
That's no problem.

What can I use to fill/seal the gaps between the cap and the hull.
I've looked at epoxy resin & paste but it'd take an awful lot to fill those gaps.

What can I use that will seal the cap to the hull?

Can you upload a photo or two? How big are these gaps?

Most boat manufacturers use a good quality marine sealant, like 3m's 4200 or 5200...if the gap is small, it won't take much, but if the gap is rather large, you might want to use a stuffing material first to make up some of the void...a decent quality polyethylene rope should work pretty good as a stuffing...

Thanks. I think 3m 5200 should work fine.

5200 is permanent so if you will never remove the cap again it's fine. You may wish to consider 4200 which is less permanent. You should also rivet or screw together usually behind/through the bow railing. Your best bet is to post some pix and the experts can give advice. 5200/4200 is fine for sealing and securing but for gap fill you probably need to glass and epoxy. There are a lot of options and methods depending on what you need.
