Yes, the fuel cap is the first place to look.
I would either call a fuel polisher or just replace the tank. Also make sure the gasket / o-ring on the filler cap are in good shape you are not letting water in they way.
However, if the boat was unused for a long time. e-10 separation is common.
If the tank were leaking the gas stink would let you know. Just MT the tank. Unlike diesel tanks, sludge is very unusual, so polishing is probably pointless. Try simply draining the tank first.
