Question 1

Do you repair MerCruiser and Volvo Penta outdrives?

Lukas · Accepted Answer

Yes, we specialize in MerCruiser Alpha/Bravo and Volvo Penta SX/DPH outdrives. We handle everything from seal replacement and gear lube leaks to complete overhauls and resealing jobs.

Question 2

What are signs that my outdrive needs repair?

Lukas · Accepted Answer

Watch for water in the gear oil, excessive vibration, shifting issues, grinding noises, or visible oil leaks near the bellows or prop. These are warning signs that your outdrive needs service ASAP.

Question 3

Do you offer on-site outdrive removal and repair?

Lukas · Accepted Answer

Yes, wherever the boat is out of the water: on a trailer, a lift or at a boatyard. An outdrive must never come off while the boat is afloat, so a boat in a slip is hauled out first, and the yard's charge is listed on your estimate. Most seal kits and gear lube changes are done on-site, and major rebuilds may go to our shop.

Question 4

How much does it cost to repair an outdrive?

Lukas · Accepted Answer

Labor is $150 an hour, plus the trip fee for work at your boat ($30 in San Pedro up to $110 in Newport Beach). An annual drive service or a minor seal job usually takes 2-4 hours; bellows, gimbal bearing and rebuild jobs take longer. You get a written estimate for labor, parts and the trip fee before any work starts, and any haul-out or yard charge is listed on it too.

Question 5

Do you replace bellows and U-joints on stern drives?

Lukas · Accepted Answer

Yes. With the boat out of the water, we replace the bellows, U-joints, gimbal bearings, shift cables, trim senders and seals that keep water out and the drive working.

Question 6

Can you pressure test my outdrive for leaks?

Lukas · Accepted Answer

Yes – we perform pressure and vacuum testing to check for internal seal failure. It's a crucial step before refilling with gear oil or reinstalling the drive.

Question 7

Do you offer a warranty on outdrive repairs?

Lukas · Accepted Answer

Yes. Our workmanship is warranted for 90 days from the invoice date; new parts carry their manufacturer's warranty. Your dated invoice lists the work and the parts, a useful record for maintenance and resale.

Question 8

What is a raw water impeller and why is it critical for my engine?

Fryderyk Florczak · Accepted Answer

The raw water impeller is a rubber rotor inside the seawater pump that pulls cooling water from the ocean or lake into your engine. If it fails, the engine can overheat within minutes, leading to serious damage such as warped heads or exhaust system failure. Regular impeller replacement is essential for engine reliability.

Question 9

What is a lower unit reseal and when is it necessary?

Fryderyk Florczak · Accepted Answer

A lower unit reseal involves replacing worn or damaged seals that protect the gearcase from water intrusion. It becomes necessary if water is found in the gear oil, seals are leaking, or after propeller shaft damage. Resealing helps prevent internal corrosion and costly gear failure.

Question 10

How do you pressure test a lower unit?

Fryderyk Florczak · Accepted Answer

We perform both pressure and vacuum testing using professional tools. This finds even small seal leaks around the prop shaft, drive shaft, shift shaft and drain screws. We test again after the work, before the unit is refilled and the boat goes back in the water.

Question 11

What happens if I keep running my boat with water in the lower unit?

Fryderyk Florczak · Accepted Answer

Running with water-contaminated gear oil can quickly destroy bearings and gears inside the lower unit. This often leads to overheating, metal damage and complete gearcase failure. Early resealing and testing can save the much higher cost of a gearcase rebuild or replacement.

Question 12

Do you replace all seals or only the leaking ones?

Fryderyk Florczak · Accepted Answer

In most cases we recommend replacing all the critical lower unit seals during a reseal: prop shaft, drive shaft and shift shaft seals. Replacing them all at once reduces the risk of future leaks and saves opening the unit again later.

Question 13

How long does a lower unit reseal service take?

Fryderyk Florczak · Accepted Answer

The labor usually takes 2-4 hours. When the job is done depends on parts and on getting the boat out of the water, and we give you a time with the written estimate.

Question 14

Is pressure testing included after the reseal?

Fryderyk Florczak · Accepted Answer

Yes. After resealing we pressure and vacuum test the unit again, before refilling it with gear oil, to confirm the new seals hold.

Question 15

Do you provide warranty on lower unit reseal work?

Fryderyk Florczak · Accepted Answer

Yes. Our workmanship is warranted for 90 days from the invoice date, and new seals (OEM or quality aftermarket) carry their manufacturer's warranty. Your invoice lists the work and the parts.

Question 16

What are outdrive bellows and why are they so important?

Fryderyk Florczak · Accepted Answer

Outdrive bellows are rubber boots on the transom assembly. The U-joint bellows and the shift cable bellows keep seawater out of the boat; the exhaust bellows carries exhaust into the drive. If the U-joint or shift cable bellows cracks, water can get into the boat, ruin the gimbal bearing and U-joints, and in the worst case sink it. Regular inspection and timely replacement are essential.

Question 17

How do I know if my bellows need to be replaced?

Fryderyk Florczak · Accepted Answer

Common signs include water in the bilge, unusual noises from the outdrive, vibration while underway, or visible cracks in the bellows. How long bellows last depends on age, sun and use, and salt water is hard on them, so follow the maker's replacement schedule and have them checked at every service.

Question 18

What is a gimbal bearing and when should it be replaced?

Fryderyk Florczak · Accepted Answer

The gimbal bearing sits in the gimbal housing on the transom assembly and supports the drive shaft where it passes through to the engine coupler. When it wears or gets wet it growls or rumbles whenever the engine runs, with a sound that changes with rpm, and it can damage the coupler and drive shaft. We inspect it whenever the bellows are replaced and recommend replacement if it is rough, noisy or rusty.

Question 19

Do you replace all bellows or only the damaged ones?

Fryderyk Florczak · Accepted Answer

We recommend replacing all three at the same time: the U-joint, exhaust and shift cable bellows. They age together, and the drive has to come off to reach any of them, so doing them together avoids paying for that labor twice. During the service we also check the clamps, the gimbal bearing, the U-joints and the engine alignment.

Question 20

Is this service available in the marina or does the boat need to be hauled out?

Fryderyk Florczak · Accepted Answer

The boat has to be out of the water: the drive comes off, and the bellows openings in the transom assembly sit at or below the waterline. We do the job with the boat on its trailer (in your storage yard or at our San Pedro shop), on a lift, or hauled out at a boatyard; haul-out and yard charges are listed on your estimate. We can inspect the bellows in the water first.
