Jabsco 12V 3-Inch Continuous Duty Flexmount Blower

The Jabsco 12V 3-Inch Continuous Duty Flexmount Blower (part 36740-0000) pushes about 150 CFM, considerably more than the standard 3-inch models. It is rated for continuous running, so it can be left on to cool an engine room or keep a compartment ventilated for hours. The flexmount bracket lets the outlet point in whichever direction the duct needs.

Higher airflow from the same 3-inch duct size means you can improve ventilation without cutting bigger holes for 4-inch hose. The motor and housing are built for long run times and are ignition protected for fuel spaces. It is a good upgrade for a boat whose engine room runs hot on long days.

Use wire sized for continuous current and protect the circuit with the fuse rating listed in the instructions. Keep the duct short, and make sure the intake end sits low in the bilge where vapor collects. If you add a thermostat or timer, make sure it is rated for the motor's current draw. Find 24V and 4-inch versions in boat outfitting.
