I think this tank is not original nor was it new. I think it was repaired and placed in this boat. This tank measurements are as follows

22 7/8 W
48 1/4 L
7 3/4 H

Does that sounds like the measurements of what would have been in a 1977 20 Seacraft MA?

Roughly 38 gallons.....

Not original !
Have RDS make you a new one and be done with it for the next 30+ years..

They built my 80 gallon tank 30 years ago and still looks new !!

they gave me a quote of $480. That is more than I can spend on the tank. So I guess I will be rednecking it for now.

That’s not too bad for 40 gallons. What was the thickness, and was it coal tar epoxied?

Michael.

I didnt ask what the thickness would be, but that is for a 35 gallon tank and without coating

I know RDS is local to you but try Sunshine Tanks for giggles. But you really need to specify thickness you want.

Think my old tank could be repaired?

Not a remote chance, i don’t believe. Been there, done that. Have the T-shirt.

My old one was worth $15 to a metal recycler.

3/16 not coated.
