Use Marine Rated Boat Parts

It is a story that is repeated too frequently. A boater jumps aboard their craft, immediately cranks the starter and then boom, the vessel explodes in a ball of fire. Transport Canada has documented the explosion of a gasoline powered boat in Halifax harbor during the summer of 2004 in an informational video. Investigators were able to determine that old automotive ignition parts had been used on the boat. Their video clip titled, “Boom! Up She Went” is available from Transport Canada's Office of Boating Safety.

There are many safety systems built into place on a government approved vessel. Improper substitution of the components within these systems can cause trouble. Boat engine parts are designed to survive and function in the harsh marine environment. While similar in appearance to their automotive cousins, marine parts must be designed and approved for use on boats. There are important differences between them.

A fire or explosion requires three components, called the fire triangle by firefighters. They are fuel, oxygen and a heat or ignition source. Explosions on gasoline powered boats can occur when fuel is spilled or leaked in the engine compartment. The gasoline vaporizes into the available air space and is primed for an explosion. This is the reason power boats use ventilation systems with blowers to pump fresh air into the engine compartment. The spark from a non-ignition protected electrical part can become the third component of the fire triangle.

Automotive electrical components do not need to be ignition protected. Transport Canada and the United States Coast Guard require small craft be built using ignition protected components. These items include blower motors, starters, distributors, alternators and ignition wires. There should be approval labels affixed to your boat that certifies it meets alls required construction standards.

  1. Great blog, can say nice information is available for free, if you add information about windsor's auto parts then it will be a great combination.

  2. Hello,

    This post is great. Boat engine parts are designed to survive and function in the harsh marine environment. While similar in appearance to their automotive cousins, marine parts must be designed and approved for use on boats. I like this kind of people who share their knowledge with others. Thanks.
