How Do I Use And Care For My Outboard Engine In Saltwater?

Flush out the outboard engine at home after every outing. This doesn't just apply to saltwater adventures, but to the fresh water outings as well.


If you have an older motor or one based upon an older design, you should buy a set of flushing "earmuffs": two flexible rubber seals attached to a metal clamp. One side can be attached to a garden hose, while the other is solid and will serve to plug a water intake. Slip the apparatus onto the lower unit where the water is taken in and then attach the earmuff to a garden hose. If there are additional water intakes that are not covered by the earmuffs, use duct tape to cover them.


Attach a garden hose to the earmuffs or mount and turn the water on. Newer motor designs already have mounts, and so the earmuffs are unnecessary.


Start up the engine. The water pump will then flush out the system. (Practice safe boating and remember to stay clear of the prop and keep the motor out of gear.)

Wash and wax your outboard engine.

Careful washing with mild soap and water not only makes your outboard look good, but also removes salt and other deposits. An application of a good quality marine wax will help to seal and protect the finish against the sun and salt.



Touch up nicks and scratches in the paint.

Inspect your outboard frequently for nicks and scratches, places where corrosion can get started and spread. Touch up any superficial scratches with a color-matched touch-up paint. On deeper scratches—especially where bare metal is exposed—use a top-quality metal primer first.



Store your engine out of direct sunlight.

The direct ultraviolet rays of the sun can damage the finish and deteriorate the exterior plastic and rubber components. For this reason, it is best to store your engine out of direct sunlight. If direct sunlight is unavoidable, keep the engine shielded with a top-quality, UV-resistant fabric cover while in storage.



Grease key points of your outboard engine.

Your EARROW comes equipped with special grease fittings to lubricate and prevent corrosion at key points where the engine pivots and swivels. Using a grease gun, apply grease through these fittings regularly, as recommended in your owner's manual. Also, periodically remove the propeller and apply a film of grease to the propeller shaft.



Replace sacrificial zinc anodes as recommended.

Most outboard engines are equipped with zinc anodes which "sacrifice" themselves in order to protect other metal parts from corrosion. To keep working properly, however, these zinc anodes need to be replaced as recommended in your owner's manual or once they dwindle to less than 50 percent of their original size. In some extraordinarily corrosive salty water areas, it is wise to add an extra zinc anode below the water line of your boat and bond it to the engine with a quality marine electrical wire. Your dealer can help you decide if this is needed. See your EARROW accessories catalog for part numbers and further information.
