When I did my 18, the foam outside of the stringers was dry, so I left it there. Had I seen any water seeping out, it would have been gone.

Stringers opened, foam removed and re-poured, fuel tank area replaced with Coosa. Fuel tank is ready to be installed after rear bulkhead and mounting tabs are completed and stringers raised.

Pro tip on fuel tank; when pre-assembling sender, cut one side of plug to prevent dropping shit in your new tank.

Nice looking work and you are moving right along. What did you coat the tank with..looks good.

strick

Atlantic Coastal Welding (Speedytanks.com) applied that epoxy coating.

price and gal size of tank if you don't mind sharing? What did you glue to bottom of tank?

I went with 46 gallon, 3/16" thick, one baffle, two pick-ups (spare, not running twins), WEMA sender, epoxy coated, aluminum 3/8" barb fitting, aluminum plug, two angle hanger mounts per side. Base on tank was $17.50/gallon. Order finalized 12/15, complete 2/3. That's a long time but if you take out 2 weeks around Christmas it's understandable. 1/4" neoprene attached with 3M 5200. The store only had tan colored 5200 so, tan it is! It's been a while since I installed a WEMA sender so PRO tip; the bolt pattern is ONE WAY ONLY, dry fit first.

Nice Build! Coming along nicely. Nice Fuel tank, its odd that 3/16'' isn't standard as it holds up so much better! I know what you mean about the anxiety working around where the sending unit goes. Maybe I missed it but what material is glued to the base of the fuel tank?

Thank you. 1/4" neoprene attached with 3M 5200

That tank looks almost too pretty to put below deck. That should last you a long long time. Your boat is looking great.

Update time....Excuse the sideways pics. Deck (1" coosa) is in and raised ~ 2-1/2", fuel tank coffin box and bilge gel-coated, splash-well area re-glassed to liner, cap re-cored with 1/2" coosa, large cut out near fuel hoses filled, splash-well large cut out needs filling, bilge hatch needs cut-out/install. Liner has been dry fit. Transom cap needs trimming/finishing, tank needs install but hatch is re-cored. Routed pvc pipe under cap for bow light wiring if I go that route. I'm leaning towards hard top with integrated Nav lights.
