1 | Inactivity | Marine engines are typically used less frequently than automobiles. These extended periods of inactivity put more stress on the oil. Critical concerns are rust and corrosion protection. |
2 | Operational Speed | Marine engines often operate at low engine speeds for prolonged periods. Lubricating oils need to circulate freely at reduced oil pressures while maintaining peak component protection. This is particularly important when followed by rapid acceleration, which subjects marine engines to high loads at relatively low engine speeds. |
3 | Contaminant Exposure | Boat and water craft engines frequently operate in humid conditions and are prone to water contamination. Water contamination increases foaming and accelerates oil oxidation. |
