Fuel tank size on 92 Sylvan 16' Sea Troller

[airshot]

Just bought a used Sylvan Sea Troller 16' aluminum boat. Previous owner does not know how big the fuel tank is, the most he ever added was 10 gallons. So....does anyone know the actual tank size of the built in fuel tank in this model?? Thanks in advance...

If you can get access to the top of the tank, they usually have a capacity on them. Measuring it is another way.

One would think it is at least 18 gal.

It is buried with hatches on both sides like many are. Appears to be aluminum so I hope I never have to replace it. Getting some dimensions and calculating was on my list, hoping someone might know. Thanks

Sometimes OEMs like SeaRay have spec sheets on their websites for older models. Fuel capacity is often contained in those specs.

You can also try KBB. They have specs too.

Have to ask what KBB is?

Tried that route but no fuel capacity info, just the fact that it has a built in tank. Went out and looked deep inside my boat...not pretty....fuel tank is under the rear live well and completely covered except for hoses going in and out. Even tried sticking my phone under there to see if anything showed up on a pic......no luck...will take a complete dissassembly of the rear section of the boat to get to the fuel tank...Mabey suck it dry then fill it back up, might be my only choice!!

Sure, throw a portable tank of fuel in the boat and run her until dry. Make sure you can switch the fuel line to the portable tank.
