Outdrive Service & Repair
The outdrive is one of the most maintenance-critical components on an I/O boat — and one of the most neglected. Failed bellows sink boats. Worn U-joints leave you stranded. Thomas Marine provides thorough outdrive service and rebuilds for Mercruiser, Volvo Penta, OMC, and other major brands.
Our Outdrive Services
Annual Outdrive Service
Gear lube drain and refill, bellows inspection, gimbal bearing check, anode replacement, and seal condition review — done every season without fail.
Bellows & U-Joint Replacement
Cracked or deteriorated bellows and failing U-joints are among the most common causes of boat sinkings. We replace both on schedule using quality components.
Full Outdrive Rebuilds
Worn-out drives torn down to their components, evaluated, rebuilt with new bearings and seals, and tested before reinstallation.
Trim Cylinder Service
Leaking or inoperative trim rams rebuilt or replaced, restoring full trim range and eliminating hydraulic fluid loss.
Signs Your Outdrive Needs Attention
- Water in the gear lube (milky or discolored)
- Vibration or clunking under load
- Visible cracks or deterioration on bellows
- Trim system that will not hold or operates erratically
- Excessive play in the drive when checked by hand
- More than one season since last full service
