OEM products are specifically designed for specific fittings and tolerances, so an aftermarket product may cause damage or not perform as well as MerCruiser’s line of products.

Proper maintenance is important to extend the life of your MerCruiser engine is needed to extend the life, usage, and value of your motor.

Saltwater, humidity, heat, electrolysis, and rough usage all take their toll on your motor. Therefore, components will degrade and need replacement over time.

So, following maintenance intervals help prevent damage and promote longer engine life. It’s also important to be aware that improperly storing the engine for long periods – most commonly during the winter months or while preparing it for sale – can cause components to degrade.
