OUR SERVICES

Inboard Boat Repair

From wake boats on Lake Conroe to cruisers in Clear Lake slips, we repair and maintain inboard and sterndrive engines right where your boat sits.

Outboard Repair

Bay boats that run Galveston Bay and the jetties work hard. We service and repair every major outboard brand, on the trailer or in the water.

Boat Electrical Repairs

Salt air and Gulf humidity get into wiring fast. We find corroded connections, charging faults, and electronics problems, then fix them properly.

Jet Ski Repair

PWC service for riders on the bay, the beachfront, and Houston’s lakes, from no-start problems to full seasonal maintenance.

Marine Diesel Repair

Diesel diagnostics and repair for sportfishers and trawlers heading offshore out of Galveston and Freeport, covering fuel, cooling, and exhaust systems.

Fiberglass

Dock rash, cracked gelcoat, and stress damage from bay chop, repaired so the hull holds up and looks right again.

Detailing

Cleaning, compounding, and protective coatings that stop Texas sun and salt from dulling your gelcoat and fading upholstery.

Trailer Repair

Saltwater launches are tough on hubs, bearings, and lights. We get your trailer road-ready before the drive down I-45.

Houston & Galveston's #1 Mobile Marine Mechanic

About Poseidon Mobile Marine Mechanics

Getting a boat to a shop in Houston usually means hooking up the trailer, sitting in traffic, and waiting days for someone to look at it. If the engine won’t start, add a tow bill before any of that happens.

We skip all of it. A Poseidon Marine technician comes to your boat, whether it’s on a lift in Clear Lake, in a slip at Kemah, on a trailer in your Pearland driveway, or tied up at a marina on Galveston Island.

Every technician is licensed, insured, and certified on the major inboard and outboard brands. The person working on your engine knows it well.

Why Choose Poseidon Marine for Boat Repair in Houston & Galveston?

Certified Technicians for Every Boat on the Texas Coast

Houston boaters run everything from 22-foot bay boats to 50-foot sportfishers, and plenty keep a wake boat on a freshwater lake as well. Our technicians are certified across inboard, outboard, and diesel platforms, so one call covers the whole fleet.

Clear Warranty & Honest Hourly Pricing

Every repair comes with a warranty. Pricing is hourly plus parts, and we tell you what we’ve found before we start the work. You won’t open an invoice and find charges nobody mentioned.

24/7 Emergency Help From Lake Conroe to the Gulf

Boats break down on Saturday mornings and the night before a tournament. Our emergency line is open around the clock, and our mobile units come to your dock, marina, or ramp across the greater Houston area and down to Galveston.

Straight Answers From People Who Show Up

The most common complaint about marine repair is simple: nobody calls back, and the boat sits for weeks. We built Poseidon Marine to fix that. You get a confirmed appointment, a technician who arrives on time, and a clear explanation of what was wrong and how to keep it from happening again.

Was looking around to find someone to do service on my jet boat. I found that they had a mobile service, so they came to my house and did a complete service on my boat. Billy was very knowledgeable and professional. I would recommend anyone looking to have service done to give them a call.

Houston & Galveston Boat Repair FAQs

Do you offer mobile boat repair in Houston and Galveston?

Yes. Poseidon Marine sends certified marine mechanics directly to your boat anywhere in the greater Houston area, including Galveston Island, Clear Lake, Kemah, Lake Conroe, and Lake Houston. Most repairs are finished on-site, so you don’t need to tow or trailer the boat to a shop.

How much does boat repair cost in Houston?

We charge an hourly labor rate plus parts, with no hidden fees. The total depends on the engine, the problem, and the parts required. A routine outboard service costs far less than a lower unit rebuild or repower. Call us with your boat and engine details for a quote before any work begins.

Can you work on my boat at a marina in Kemah or Clear Lake?

Yes. We regularly service boats in marina slips around Clear Lake, Kemah, and Seabrook. Some marinas ask outside contractors for proof of insurance, which we can provide. When you book, include your marina name and slip number so the technician can find the boat quickly.

How does Galveston Bay's saltwater affect my boat engine?

Saltwater speeds up corrosion in cooling passages, electrical connections, and metal components like anodes, hubs, and steering parts. Brackish bay water can also leave deposits that restrict cooling flow and cause overheating. Flushing the engine after every trip and keeping up with scheduled service are the best ways to prevent costly damage.

How often should I service my outboard in Texas?

Most outboard manufacturers recommend a full service every 100 hours or once a year, whichever comes first. Houston’s heat and long boating season mean many owners hit 100 hours sooner than they expect. A typical service covers the water pump impeller, gear oil, spark plugs, fuel filters, and anodes.

Do you repair boats on Lake Conroe and Lake Houston?

Yes. We service boats on Lake Conroe, Lake Houston, and other freshwater lakes around the region. Freshwater boats see a lot of inboard and wake-boat traffic, and we’re certified on those engines as well as outboards and sterndrives.

What boat and engine brands do you work on?

We work on all major engine brands, including Yamaha, Mercury, Suzuki, Honda, Evinrude, Johnson, Tohatsu, Volvo Penta, Detroit Diesel, and BRP. We also service marine electronics from Garmin, Simrad, Raymarine, Lowrance, Furuno, and Humminbird. Poseidon Marine is also an authorized Honda Marine dealer.

Do you offer emergency boat repair in Houston?

Yes. Our emergency line is available 24/7. If your boat breaks down at the dock, at the ramp, or before a trip, call us and we’ll dispatch the nearest available technician to diagnose the problem and get you running as quickly as possible.

Should I get my boat inspected before hurricane season?

Yes. A pre-season check before June confirms your bilge pumps, batteries, and charging system work, and that the engine will run if you need to move the boat on short notice. It’s also a good time to check trailer bearings, tires, and lights in case you need to haul out ahead of a storm.

Can I finance a boat repair or repower?

Yes. Poseidon Marine offers financing on all services, including major repairs and repowers. Rates are competitive, terms are straightforward, and approval is quick. Ask about financing when you call for a quote.
