We have our outboard stowed for trips on one side of pushpit, gas bbq on the other, outboard fuel tank gets stored in ventilated locker (same one as gas bottle). We are yet to blow up! Outboard is only run dry of fuel when its going to be stored for a while at the end of a trip. Connecting/disconnecting the outboard fuel line can leave a few drops of fuel about, so I just let it dry off and remember to close fuel tank breather before stowing in locker. Probably not a good idea to be doing all this at the same time as cooking on the bbq, so just do one job before the other.
Thats encouraging.
I have read that the gas given off from fuel and the LPG are heavier than air and can sit at the bottom of the boat.
I have even heard of someone vacuuming the bilge to get rid of them.
I am thinking that as long as I can't smell fuel I should be OK.
Surely the morning after stopping for the night should be fine.
The motor, fuel line and tank are nearly new.
