Lower Unit Damage From Flats and Reefs Requires Precision Work
Seals, Gear Cases, and Prop Shaft Repairs
Tavernier residents choose lower unit repair from Real Extreme Marine because shallow-water navigation and nearshore fishing increase the likelihood of impact damage, seal wear, and gear case leaks. Whether you clipped a rock on a falling tide or noticed gear oil leaking after a hard grounding, addressing lower unit issues quickly protects your engine and drivetrain from cascading damage.
The team specializes in seal replacement, gear case rebuilds, and prop shaft alignment. These are common repairs in the Keys, where boaters frequently operate in skinny water, around coral structures, and over hard bottom. Damage that seems minor on the surface can lead to water intrusion, bearing failure, and expensive engine repairs if ignored.
Not every lower unit issue requires a full rebuild or replacement. The approach is straightforward: inspect the damage, explain what's repairable, and provide clear guidance on whether a fix or a swap makes the most sense. You'll know the cost, the timeline, and the expected outcome before any work begins.
Mobile service is available when the damage allows for on-site work. For more involved rebuilds, the lower unit is removed, serviced, and reinstalled with precision to ensure smooth operation and long-term reliability. Every reassembly is tested under load to confirm proper gear engagement and seal integrity.
