Keeping Your Outdrive Watertight And Reliable

Your outdrive is one of the hardest working parts of your boat, transferring power from the engine to the water while sealing out everything around it. We service and repair MerCruiser and Volvo Penta sterndrives along with other major outdrive brands, from a worn bellows or gimbal bearing to a full drive rebuild.

Catching a failing bellows or seal early is far less expensive than the water damage it can cause if it fails on the water, so we check these wear items on every outdrive that comes through our shop.

What We Repair

Outdrive Repair Beyond The Basics

Bellows And U-Joint Replacement

We replace worn exhaust, shift, and U-joint bellows before they crack and let water into the boat or the drive.

Gimbal Bearing Service

A worn gimbal bearing causes vibration and premature wear on the U-joints, so we inspect and replace it as part of a full drive service.

Gear Lube And Seal Service

We check outdrive gear lube for water intrusion and replace worn seals before they lead to a costly gear housing repair.

Shift Cable And Trim Repair

Sticky shifting, a slipping trim system, or a leaking trim ram are all diagnosed and repaired in house.

Our Process

How Outdrive Service And Repair Works

1

Diagnosis And Drive Removal

We identify the issue, whether it is a leak, vibration, shifting problem, or a routine wear item, and remove the drive if a teardown is needed.

2

Bellows Bearing And Seal Inspection

Every bellows, U-joint, gimbal bearing, and seal is inspected as part of the same visit and replaced as needed.

3

Gear Housing And Shift Repair

We repair or rebuild the gear housing and shift mechanism as required, using manufacturer specified parts and torque values.

4

Reassembly And Pressure Test

The drive is reassembled and pressure tested to confirm every seal holds before it goes back on your boat.

5

Water Test

We run your boat on the water to confirm smooth shifting, proper trim operation, and no leaks under load.

Frequently Asked Questions

Outdrive Service Questions Answered

Cracking, hardening, or visible wear on the rubber bellows are signs it needs replacing. We recommend inspecting bellows every season, since a failed bellows can let water into the boat.

Yes. MerCruiser and Volvo Penta sterndrives are two of our most serviced platforms, alongside other major outdrive brands.

A worn gimbal bearing, damaged U-joint, or a bent propeller shaft are the most common causes. We diagnose the specific cause before recommending a repair.

In most cases, yes. A full outdrive rebuild replaces bearings, seals, bellows, and gears as needed, and is often significantly less expensive than a new unit.
