Re: Purpose of a blower on an outboard
The purpose of the bilge blower is to remove hazardous fumes from the bilge to prevent fire or explosion.<br /><br />Since fuel vapor is heavier than air, it will sink to the bottom of the area where the tank is located, and any adjacent area to which it can migrate.<br /><br />You don't have to locate the blower there; you can connect the blower's input to hoses that you route there. On multiple tanks, you might fabricate yourself a yoke to connect all three to the blower's input.<br /><br />Plumbing supplies for DWV would work great. You could use a combination of rigid pvc and rubber fittings to make your yoke for your multiple inputs. Then hookup with regular bilge blower hose.<br /><br />Then run the blower for a few minutes prior to starting anything else electrical for that particular outing. Normally ram air will suffice while underway, but with your rig, you might run your blower more often.<br /><br />My 2c,<br /><br />Mark
