Where to keep the outboard gas can
I concur with GordMay''s opinion that gasoline "VAPORS" can be lighter than air, therefore require a vented cover if enclosed in a compartment. Anchor & propane lockers do not meet this requirement.
Our outboard jerry can is stored in one of two teak benches, secured to the teak aft deck over fixed chocks. The bench lids are also constructed of teak, grated for ventilation of gas vapors. Additionally, there are drain holes in the bench bases, which promote a natural convection cycle.
We do have a dedicated propane locker within a side deck, but keep a spare propane bottle in the other aft deck bench locker. I would recommend that you keep the gas can out in the open, if a top-vented compartment is unavailable.
Edit after GordMays next reply - Gasoline vapors are lighter than propane, slightly heavier that air, but require air flow for total elimination of explosive vapors. Therefore, it is important that the cover be vented.
