Don't wait until the first warm weekend to find out your boat won't start. We come to you — driveway, storage unit, or marina — and get your boat lake-ready before the season hits.
Also called boat summerization or de-winterization — same service, different names.
A boat that sat all winter is not the same boat you parked in October. Fuel has aged and separated. Batteries have drained. Water has settled in fuel-water separators and the bilge. Rubber components — hoses, impellers, bellows — have been dry and cold for six months. Mice and insects have made themselves at home in your air intakes, fuse panels, and engine compartment.
Launching on the first warm weekend without proper commissioning is how Spokane boaters end up stranded on Long Lake, Newman Lake, or Coeur d'Alene with a no-start condition, a cracked impeller, or a fuel-system failure — on what was supposed to be the first fun Saturday of the year.
Spokane Boat Repair is the area's top-rated mobile marine service team. We come to your boat — at your house, at Shadow Storage on Lake Roosevelt, at your marina slip — and complete full spring commissioning on-site. Most commissioning jobs are done in 60–90 minutes. Your boat is lake-ready when we leave.
A proper spring commissioning is not just "hook up the battery and turn the key." Every boat needs a specific startup procedure, and skipping steps is how you end up with a failed impeller running the engine dry at the lake. Here's what we do on every service call:
In the Spokane area, the spring commissioning window is March through May. Early birds who book in March get first pick of appointment slots and can plan their first launch weekend with confidence. The procrastinator trap is waiting until the first 70-degree weekend, calling on Friday, and finding out we can't get to you until the following Wednesday — after you've already cancelled the lake day.
Here's the order that actually works: (1) book spring commissioning as soon as daytime temperatures hit the 50s and the snow is off the boat, (2) we do the service within 1–2 weeks, (3) you have 2–3 weekends of buffer before your first planned launch to shake down any issues we flag. This rhythm is how Spokane Boat Repair customers launch on the first warm weekend instead of spending it watching neighbors trailer out.
If you missed winterization last fall — or if you bought a boat over the winter and don't know its history — call now. A spring commissioning on a boat of unknown history also includes a deeper inspection to catch any freeze damage, fuel system issues, or hidden problems before they become lake-day disasters.
Pricing depends on your engine type, boat size, and whether additional services (impeller replacement, fluid changes, shrinkwrap removal) are bundled in. Typical ranges for mobile service in the Spokane area:
Standard commissioning covers battery, fuel system, cooling recommissioning, fluids inspection, engine start and run-up, controls, safety check, and full inspection. If impeller replacement, lower unit service, or other repairs are needed, we price those separately and handle them on the same visit whenever possible. Call 509-408-3075 for an exact quote.
We commission every outboard brand sold in the Spokane area, plus MerCruiser, Volvo Penta, and Indmar inboards. Same mobile service, same tools, same expertise across all brands.

The dealership commissioning model is painful: trailer the boat to the shop, drop it off, wait two to four weeks during the busiest part of their season, pick it up, hope they got to it. By the time you get your boat back, the weekend weather window has closed.
We reverse that equation. You call, we come to the boat, we commission on-site. Most jobs are completed in 60–90 minutes on a single visit. For boats at Shadow Storage on Lake Roosevelt, Coeur d'Alene marinas, Liberty Lake, or Newman Lake, mobile service eliminates the trailer-and-wait cycle entirely.
Mobile spring commissioning service across the greater Spokane and North Idaho region: Spokane, Spokane Valley, Liberty Lake, Otis Orchards, Cheney, Airway Heights, Fairwood, Dishman, Mead, Deer Park, Post Falls, Coeur d'Alene, Hayden, Rathdrum, and surrounding areas. We also cover the major lakes — Lake Coeur d'Alene, Lake Roosevelt, Newman Lake, Liberty Lake, Long Lake, Loon Lake, Hayden Lake, and Priest Lake.
If your boat is stored anywhere in the greater Spokane metro area or within about 50 miles of the city, we'll get to you before your first launch weekend.

See All Reviews on Google →Book 2–3 weeks before your first planned launch. March through early May is ideal. Call as soon as daytime temperatures hit the 50s — our April and early-May appointments fill up fast, and waiting until the first warm weekend usually means missing the launch day you were hoping to hit.
Most outboards run $200–$350. Stern drives run $300–$500. Inboard ski and wake boats run $350–$600. Twin-engine setups run $450–$800. Call 509-408-3075 with your boat and engine info for an exact quote.
Battery service, fuel system check, cooling system recommissioning, oil and filter check, lower unit inspection, engine start and run-up to operating temperature under load, steering and controls check, bilge pump and blower verification, safety gear check, and a full visual inspection of belts, hoses, and bellows. Every step is included on every service call.
Yes. Winterization protects the boat over the off-season. Commissioning is the opposite procedure — removing antifreeze, recharging batteries, priming the fuel system, and verifying everything works under load. A boat is not ready to launch just because it was properly winterized. Both services are part of a safe seasonal cycle.
Call us immediately. A boat that sat all winter without proper winterization may have freeze damage, fuel system issues, or water intrusion. Commissioning on an unwinterized boat includes a deeper diagnostic inspection to catch hidden problems before you launch. Early detection is the difference between a $200 fix and a $3,000 rebuild.
Yes. Mobile commissioning at Shadow Storage, Lake Roosevelt marinas, Coeur d'Alene marinas, Liberty Lake, Newman Lake, and most regional storage facilities is one of our most common spring calls. We come to the boat — you don't have to trailer it.
Yes. We commission Indmar, PCM, and Ilmor inboards including Malibu, MasterCraft, Supra, Moomba, Centurion, Axis, and all closed-cooling V-drive setups. Inboard commissioning includes ballast system prime, heat exchanger verification on closed-cooling setups, and all the standard startup checks.
Commissioning is the seasonal startup procedure — wake the boat up from storage, verify everything works, get it lake-ready. A tune-up is preventive maintenance — spark plugs, fuel filters, oil, impeller, and other wear items replaced on a schedule. Many boats need both in the same season. We bundle them if you want a single-visit service.
You get a written estimate before any repair work happens. Common spring findings are dead batteries, failed impellers, aged fuel that needs to be drained, corroded connections, and worn belts or hoses. Most issues we can fix same-day. If parts are required, we order and schedule a return visit — priority scheduling for existing commissioning customers.
We come wherever your boat is. Residential driveway, apartment parking lot, storage unit, marina slip, or boat yard. If we can physically reach the boat, we can commission it on-site.
Mobile commissioning at your driveway, storage unit, or marina. Most appointments scheduled within 7–10 days. Call now before the spring schedule fills up.
