74 Weekender fuel tank

[wgmtman]

Just inherited a 74 weekender which only has a 12 gal portable tank. This probably won't get me far with the Johnson 150 on it. Does anyone know about permanent tanks for this boat?

12 gallons wont get you too far...what do you have for compartments down below? is this what the boat came with from the factory? seems odd if it did....
