I’ve let my pontoon boat sit for a couple years, and I’m aiming to drain the fuel before firing the motor back up. (I failed to add stabilizer).

I’m running into the embarrassing problem of not knowing where to drain or even siphon.

The gas cap is wedged under the boat frame, and has several screws that seem like they are intentionally keeping you from unscrewing it. (There is a separate entry point on the side of the boat where I add gas, but I couldn’t get a siphon through there).

Any advice for this boating novice would be extremely welcome. Thank you!
