Bilge blowers - Do you run them all the time?
Ive had outboards or diesels for a while but I'm getting back into a petrol sterndrive. Previously with inboard petrol I'd open the hatch and run the blowers for 3-4 minutes then start engines, run a minute or two before closing the hatch and I'd turn OFF the blowers. I'm now thinking that as long as the engine is running, shouldn't the blowers be turned ON?
Petrol fumes are heavier than air so with the hatch closed, any petrol fumes are 'trapped' in the bottom of the engine bay, so blower intakes are located low down.
Maybe a stupid question but do you run your bilge blowers all the time?

As long as you make sure they are on a fused circuit, which of course they should be whoever installed them. I have seen them melt/smolder before. But yes, run them at every start up; and visually inspect the bilge every new day of boating, or after every longer break. (After a raft up, after a meal, anything over an hour or so.)
