Have battery compartment open and can smell some fumes.I check line and hatch with flash light but can not see anything wrong or damp.Can the tanks be venting off some?
If it is, the vent should be outside the closed compartments. Gas fumes are nothing to fool with, I would get a mechanic in there before you do anything else.
That is a dangerous situation. There should be no fumes in the bilge. Look for leaks at the fill, vent and fuel line that leads to the engine. Sometimes the tanks themselves can leak. Is your tank aluminum or plastic?
Not sure what tanks were made of in that year and can't see in there. The hatch has been open for over a week as I have been working on new fish finder,maybe fumes from vent are being sucked down? I will close for a while then check before I take it to the shop.
How old is your boat? tanks can wear out, rub or vibrate loose, gas lines and hoses can wear or rot from ethanol too. Excessive fumes is nothing to take lightly, I would be disconnecting your battery ASAP until you fix the issue.
