It works off the factory multi speed switch. Works ok but... i ideally need a more powerful inline fan. This one is about 4" in/out 120CFM 4.5A, and i really need a 4">5" in/out 180CFM+ to work as well as the OEM did. Like one of these: http://www.go2marine.com/product.do?no=52026F Anyone know a local supplier?
