Default Blower motor

Apologies if this is in the wrong section, but i figure it is engine related. Anyway, in my continuance of learning systems, switches, etc. I came across this beauty work. The blower motor looks like it was replaced, but the duct was never reattached. Also, it is currently set to be blowing air into the engine bay instead of sucking it out and venting it. I've read mixed opinions on how this should function, but in my mind sucking the air out seems to be the proper way. Also also, should there be additional duct work going further down to the bilge, in front of the engine, or anywhere else? I wonder how long the previous owner was running like this...I bet most of last season

The blower 'sucks' air out from the bilge and sends it overboard. There should be duct work going from the bottom of the blower down as low into the bilge as possible. It only need to get as low as possible since gas vapor is heavier than air and sinks to the lowest place in the bilge.

There may be differing 'opinions', but those people are idiots.

This works like the vent in your bathroom venting OUT the moisture, in engine compartment, venting OUT the gas vapor that may cause explosion or fire in the engine compartment.

+1 this is also as stated by the CG.

To suck the gas vapors out is what you want. Turn it on for at least 4 minutes before you start your engine. In very hot weather I would turn the blower on when at the off plane speed to circulate the bilge air. Your call on that one.

If you ever wanted to get a VSC ( vessel safety check) you would have to fix this which it sounds like you are.

Good luck

I run the blower before starting, and anytime an engine is running, whether moving or not. Can't hurt.

No reason to run the blower when on plane.

I repeat my last 2 words... Can't hurt.


Besides, I usually forget I have it on till I shut down and hear them running. :-)

Blower motors definitely blow air of out of the bilge area, meaning, they suck the air out. If its pulling air into the bilge, its wrong.

Thanks for the replies and confirmation. I'll look to add a little more ducting to get further down the bilge
