Re: Consequence of not using the blower motor to suck out fumes......

Proper use of a bilge blower is good practice. However you need to keep in mind that a bilge blower will only address a symptom and not a problem. A bower will remove the fumes which shouldn’t be there in the first place, and if there are fumes that are removed by a blower the source of those fumes is not going to be fixed.

A carb is always going to have fumes, there is no way around it. At some point in the carb there is fuel exposed to air in a less than perfect seal. The trick is that a normal carb has very few fumes, but never zero. A single seal drying out without you realizing it could cause it to send alot more raw fuel into the atmosphere.

EFI on the other hand, should never have fumes. Injectors seal perfectly, if they don't, you have other issues.

I like to open my engine hatch when when I am docked after a good long run. And ususally run my blower for atleast 3-06 minutes before starting.

Yep, carburetor bowls are vented, however I would still suggest that if you can smell gas fumes there is a problem that needs addressing. - Carbs shouldn't vent that much in the way of fumes - downdraft or updraft.
