Main Differences Between Marine and Industrial Engines:

Starter – The starter on a marine application is coated in an epoxy instead of just regular paint or a bare casting used for an industrial diesel application. The epoxy coating is a rust preventative used instead of aluminum, industrial cast iron or steel material. A marine starter is also sealed at certain points to keep the water out. The casings on a marine starter are spot welded for extra strength to keep from breaking. An automotive or industrial engine, running gasoline and not diesel, can split and allow sparks into the engine bilge.

Marine AlternatorMarine Alternator

Alternator – With a marine rated alternator, near the screen there is an additional plate behind the fan. There is also an additional spark arrestor screen on the back. These plates keep a spark from entering the bilge. Engine fires at sea are no joke and every measure to prevent them must be taken.

Distributors – With gasoline powered marine engines the distributor and distributor cap are points of corrosion and fire hazard. The distributor’s job is to route secondary high voltage current to the spark plug so that it may fire in the correct order. This piece of equipment can pose a significant fire hazard and must be upgraded for marine applications. Automotive distributors have an automatic vacuum advance whereas marine distributors do not due to increased risk of a spark. A pressurized vacuum adds stress to the internal components and increases the likelihood of structural failure. Marine distributors contain different internal operating arrangements. The springs are heavier to sustain higher constant RPMs. The points also do not float in marine distributors vs. an automotive or industrial distributor. The spark arrestor vent and distributor caps are also different in marine applications. They are usually made of brass to prevent corrosion. In automotive applications the vent, caps and terminals are all made from aluminum. The brass terminals are actually much better conductors of electricity and stand up to the humid environment much better. Look for electrical components that are rated SAEJ1171; this international rating means the part is safe for marine applications.
