Stupid question....first full year with the boat starting soon.

Which is the aux tank and which is the main and what are their capacities? I mean which is forward and which is aft (including the fuel fills).

Thanks

1999 Marlin

I agree with above. Forward tank is forward fill, aft tank is aft fill. On our 2006 Marlin both tanks are about 150 gallons, I not certain but I think the main (forward) is slightly more than 150 gallons.

forward tank is main and rear is aux, the older 1990's-2000's models have a 306 gal capicity, 153 each and the new ones around 14' are 286 gallons

Main tank is fore and aux is aft. In earlier boats the main was 156 gallons and aft was 150 gal (306 total). It dropped to 300 at one point and now is 141 gallon each (282 total). I'm guessing with each upgrade they have taken some space for other uses.
