What is the difference between a genuine and aftermarket lower unit?

Genuine lower units are specifically designed for your outboard model, ensuring perfect compatibility and optimal performance. Aftermarket parts may have different tolerances and lower quality materials, leading to premature wear and potential engine damage.

How can I tell if my lower unit is damaged?

Signs of a damaged lower unit include abnormal vibrations, metallic noises, difficulty shifting gears, oil leaks, and overheating. In these cases, it's advisable to consult a qualified mechanic for an accurate diagnosis.

How often should I change my lower unit oil?

The lower unit oil should be changed every 100 hours of operation or at least once a year. Use a specific marine lower unit oil, which offers greater protection against corrosion and wear.

What happens if water gets into the lower unit?

Water in the lower unit can cause irreparable damage to the gears and bearings due to corrosion and loss of lubrication. It is essential to immediately replace damaged seals and contaminated oil.
