I/O Seacraft Do I Need a Blower?

[Islandtrader]

The blower should be mounted as low as possible in the bilge,as gas vapors settle,but it has to also stay dry.Hook up the outlet side of the blower to a flexible vent hose,and attach it to a rear facing vent to exhaust the vapors.

This may be dumb but does it make any difference where the blower is mounted? As long as the hose is lying in the bottom of the bilge sucking air?

BW and Snook...my vents are clam shells that were mounted on the rear cap pointing back. The ones on the engine box are pointing down and towards the transom. For handles and air.

So I am wondering if this will work when the blower is not running?
