Why Choose Us?

- We service all major outboard brands and engine sizes, from small 4-stroke kickers to high-horsepower offshore motors.

Outboard Engine Diagnostics & Motor Repair
A proper diagnosis is the foundation of every successful engine fix. We connect to your engine's onboard computer, run compression tests, and inspect fuel delivery and ignition systems — covering everything from minor motor repair to full powerhead rebuilds — to pinpoint the root cause before touching a wrench. Skipping this step is how small problems become expensive ones.
Serving Stuart & Surrounding Areas
Stuart Mobile Boat Mechanic performs engine service and boat repair throughout Martin County and the northern Palm Beach County coastline. We regularly serve boaters in Jensen Beach, Palm City, Hobe Sound, Port St. Lucie, and Fort Pierce, reaching vessels at private docks, marina slips, and dry-storage yards alike. We also cover Tequesta, Jupiter, and Indiantown, so whether you're keeping your boat on the St. Lucie River, the Indian River Lagoon, or a western county storage facility, we can come to you. Within Stuart itself we work across every neighborhood — from Sailfish Point and Sewall's Point to Port Salerno and the St. Lucie Inlet Area — so no one has to trailer their boat for a repair that can be handled right where it sits.

Common Signs Your Outboard Motor Needs Service
Catching outboard motor trouble early keeps a minor fix from turning into a full engine replacement — and in South Florida's year-round boating season, a breakdown can cost you far more than just a repair bill.
Hard Starting or No Start:
If your outboard cranks but won't fire, or takes several attempts to start, you likely have a fuel delivery, ignition, or compression issue that will worsen with every outing.
Overheating Warning:
A rising temperature alarm or steam from the exhaust signals a failing impeller or blocked cooling passage — ignore it and you risk warping the powerhead within minutes.
Rough Idle or Misfiring:
Sputtering at idle or under load usually points to dirty fuel injectors, worn spark plugs, or a failing ignition coil — all straightforward fixes when caught before they strand you.
Milky or Discolored Gear Oil:
White or foamy gear oil in the lower unit means water intrusion through a failed seal — left untreated, it destroys the gears and bearings inside.
Frequently Asked Questions
How much does outboard repair typically cost?
Costs vary widely depending on the issue — a basic tune-up or impeller swap runs far less than a lower unit rebuild or powerhead repair. We provide a transparent estimate before any work begins so you know exactly what to expect. Contact us for a free quote specific to your engine make, model, and symptoms.
How long does an outboard repair take?
Many common repairs — spark plugs, impellers, fuel filters, and minor electrical issues — can be completed in a single visit, often the same day you call. More involved work like lower unit rebuilds or powerhead service may require a follow-up appointment depending on parts availability. We'll give you a realistic time estimate upfront.
Do I need to haul my boat out for outboard service?
For the vast majority of outboard repairs, no haul-out is needed. We work directly at your dock, marina slip, or storage yard, which saves you haul-out fees and the hassle of trailering. Only in rare cases involving below-waterline structural work would we recommend a yard visit.
What outboard brands do you service?
We work on all major outboard motors including Yamaha, Mercury, Honda, Suzuki, Evinrude, and Johnson, covering both two-stroke and four-stroke engines. If you're unsure whether your motor is something we can handle, just call (772) 403-9110 and we'll let you know right away.
How often should I service my outboard?
Most manufacturers recommend a full outboard service every 100 hours or once a year, whichever comes first. In South Florida's year-round boating environment, annual service is the minimum — boats used heavily in saltwater benefit from more frequent checks of the cooling system and lower unit seals.
