Common Lower Unit Problems
- Milky or contaminated gear lube: indicates water intrusion from failed propshaft, driveshaft, or shift shaft seals.
- Oil leaking near prop or drain screws: commonly worn seal kits or damaged drain plug washers.
- Grinding or whining noise in gear: often worn gears or bearings inside the gearcase.
- Hard shifting or stuck in gear: inspect internal shift components and linkage alignment.
- Overheating at speed: check water pickup inlets for blockage or damage.
Tip: Any time the lower unit is removed or opened, replace seals and inspect bearings and gears carefully. Early wear detection prevents catastrophic gearcase failure.
