Frequently Asked Questions (FAQs)

1. What do blowers do on a boat?

In gas-powered boats, there should be one blower for each engine. The blower's primary job is to remove any gasoline vapors in the engine room. These vapors are highly explosive and if ignited by a spark can destroy the boat and anyone on or beside the boat.

2. Do I need a bilge blower?

A bilge blower is important not only because the USCG may require it, but also because your life may depend on it. The Coast Guard stipulates the use of a mechanical ventilation system for all non-open type boats built after July 31, 1980 which run on gasoline.
