Jabsco 12V 4-Inch 250 CFM Flexmount Heavy Duty Blower

The Jabsco 12V 4-Inch Heavy Duty Flexmount Blower (part 35770-0092) moves about 250 CFM and is rated for continuous running. It combines the high flow of a 4-inch blower with the flexible mounting of the universal bracket. That makes it a strong choice for crowded engine rooms that need ventilation for hours at a time.

The bracket lets the outlet rotate to line up with the duct path, so hoses do not have to bend sharply. Jabsco rates this motor for extended operation, and the blower is ignition protected for gasoline engine spaces. It is a step up from the standard 35440 flexmount when the blower must run while underway.

Run 4-inch hose to an exterior vent with the intake end low in the bilge. Fuse the positive lead close to the battery or panel and route the cable away from exhaust manifolds and belts. Check the hose clamps and ducting each season, since vibration can loosen them. Find 24V and AC versions in boat outfitting.
