Re: Hull Vents
If it's an I/O, Bilge/Hull vents are required as per Coast Guard regulations.Blowers that are ignition protected,and spark proof are also required,and should be run for a few minutes to exhaust any gas vapors.
The purpose,of vents and blowers,are to vent,and remove any gasoline vapors out of the bilge,that could send you on a nice amusement park ride,when you turn the ignition key.Gasoline vapors(if any) being heavier than air,settle in the lowest areas,and need to be removed
This is one of the regs.that makes sense,as boat explosions from gas vapors,are not all that uncommon.
They are not required(I think),on outboard powered vessels,but even they, can benefit from the vents.Any air, circulating through the hull and bilge is never a bad thing.
