Fuel tank size

[elwilliams13]

Does anyone know what size were the factory tanks on a 1979 235. Mine has the large main and smaller reserve but unsure of the capacity. Previous owner had no clue.

Thanks,

If it's actually a 1979 23 footer, it should have the same setup as the 25 of that model years, which would be 86 gal main with a 38 gal optional reserve. Hope this helps. If you're still not sure. empty them out and top'em off[]
