You must have at least two ventilator ducts—one exhaust duct and one intake duct. Intake ducting must extend midway to the bilge, or at least below the carburetor air intake level. Exhaust ducting must extend from the lower bilge to cowls in the open air. Manufacturers must install exhaust blowers in engine compartments so gasoline fumes can escape before the engines start. These blowers should be turned on at least four minutes before the engine is started to make sure that any explosive fumes have been removed.
A spark from the electrical or ignition systems can cause an explosion if gasoline fumes are present.
Boats built after July 31, 1980, having enclosed gasoline engines and fuel tank compartments, must have power-operated ventilation systems.

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
