Installation and Operation

Replacing this element is an investment in the longevity of your engine. Regular lubrication of the bearing prevents premature wear and corrosion, especially in harsh marine conditions. We recommend using waterproof greases during servicing. Avoid running the engine with a damaged bearing, as this can lead to serious transom damage.
