Your boat won't start, overheats, loses power, or throws a code — and you don't want to trailer it to a shop and wait three weeks. We come to you, diagnose on the spot, and fix most issues in a single visit.
Finding a good boat mechanic in Spokane used to mean trailering your boat to a dealership, dropping it off in a parking lot, and waiting two to six weeks in peak season — all while the good weather passes you by. Many Spokane boat owners don't even own a trailer. Their boat lives at a marina, at Shadow Storage on Lake Roosevelt, or at a lakefront property from May to October and can't easily be moved.
Spokane Boat Repair is a full-service mobile marine mechanic team serving the greater Spokane and North Idaho region. We bring the diagnostic equipment, the parts, and the expertise directly to your boat — at your driveway, your storage unit, your marina slip, or a boat ramp. Most repairs and diagnostics are completed in a single on-site visit.
We service every major outboard brand, every major stern drive, and every major inboard. Mercury, Yamaha, Evinrude, Honda Marine, Suzuki, Tohatsu, MerCruiser, Volvo Penta, Indmar, PCM, Ilmor — if it's a marine engine, we can diagnose and repair it.
Most Spokane boat owners assume that serious diagnostic work requires a full shop. The reality is that 80% of boat repairs can be completed at your location with the right mobile equipment. Here's what we handle on-site:
The Spokane boating climate is hard on engines. Long off-season (6+ months of storage), cold-soaked fuel, ethanol-blended gasoline, and dry rubber components all produce a predictable set of spring and early-summer failures:
Usually fuel-related (stale gas, varnished carburetor, clogged injector), battery-related (low charge, bad cell, corroded terminals), or ignition-related (fouled plug, bad coil).
Almost always a failed water pump impeller. Impeller rubber dries out over winter and loses the ability to move water. Often discovered the first trip of the season.
Fuel delivery issue (partially clogged filter, weak pump), ignition breakdown under load, or exhaust restriction. Diagnosed with a live scan tool during a run.
Carburetor or fuel injector fouling, vacuum leak, or ignition issue. Common on boats where fuel sat all winter without stabilizer.
Failed trim pump motor, low hydraulic fluid, stuck ram, or broken wiring. Usually happens right when you need to trim up at the ramp.
Milky gear oil means failed seals. Caught early, it's a $200–$400 seal job. Caught late, it's a $2,000–$5,000 lower unit rebuild.
Hydraulic steering leak, seized cable steering, or helm pump failure. Safety-critical — don't launch with a sticky helm.
Corroded grounds, failed switches, intermittent gauges, dead bilge pumps, navigation lights that won't work. Boats and moisture don't mix — but we trace every wire.
Most mobile boat mechanic calls fall into predictable ranges. Here's what to expect:
The diagnostic fee is applied toward the repair if you book the work with us. Call 509-408-3075 with a description of the issue — most quotes can be given over the phone in under five minutes and we'll tell you if your specific problem needs an on-site diagnostic or can be priced by symptom.

We come to you. Residential driveway, storage unit, marina slip, lakefront property, or boat ramp. Mobile service is our default, not an upcharge. We only require you to come to us in rare major-repair situations that physically need a shop lift.
Every major marine engine sold in the Spokane area. Mercury, Yamaha, Evinrude, Honda Marine, Suzuki, Tohatsu, Nissan Marine, MerCruiser, Volvo Penta, Indmar, PCM, and Ilmor. Outboards, stern drives, inboards, 2-stroke, 4-stroke, carbureted, fuel-injected. If it's a marine engine, we can work on it.
Standard scheduling is 5–10 days in peak season (April through August) and faster in shoulder season. True emergencies are triaged — a dead boat at a ramp or a boat overheating on launch day moves to the top of the queue when we can.
Yes. Call 509-408-3075 with a description of the problem and your engine model. Most estimates are provided in under five minutes. Some problems truly require an on-site diagnostic, and we'll tell you which is which up-front.
Rare but possible. For jobs that physically require a shop (major powerhead work, hull repair, major outdrive rebuilds), we can arrange removal, shop work, and return. You stay informed throughout.
We triage urgency. A dead boat stranded at a launch ramp, a boat overheating on a tow-home, or a freeze-season emergency with a boat about to get damaged — those move to the top of the schedule. We don't have a formal 24/7 line, but we respond fast to real emergencies.
Everything needed for most service calls: diagnostic scan tool, compression gauge, fuel pressure test gear, common filters, impellers, spark plugs, fresh oils, marine antifreeze, fuel stabilizer, tools for every major engine brand, and common wear parts. We restock daily during peak season.
Yes. Pre-purchase inspections are one of our most valuable services. We'll meet the seller and boat wherever it is, perform a full mechanical inspection, compression test the engine, inspect the hull and drive system, and give you an honest assessment before you hand over any money. Money well spent on any used boat over a few thousand dollars.
Won't start, overheating, losing power, or just time for service? Mobile boat mechanic at your driveway, storage unit, or marina. Most estimates given over the phone in under five minutes.
