Spokane winters are hard on boats. Fuel goes stale, batteries drain, water pump impellers take a permanent set, rodents chew wiring, and stabilizer wears off around month four. If you skip summerization and just launch in May, you're rolling the dice on an overheating outboard, a no-start, or an impeller failure 200 yards from the dock.
Summerization is the other half of winterization. One takes the boat safely out of service, the other brings it back safely. Owners who summerize every year spend a fraction on repairs compared to owners who don't. It's the cheapest season of marine maintenance you'll ever do.
Every summerization is a full mechanical wake-up. We don't just swap fluids — we systematically verify every system that was protected for winter.
The sweet spot in the Spokane area is mid-March through mid-May. Schedule too early and batteries have to sit charged for weeks before launch. Schedule too late and you're stuck waiting behind every other boat owner in the Inland Northwest when the first 75-degree Saturday hits.
Our calendar fills first for weekends in April and the week before Memorial Day. If you want guaranteed water access for the long weekend, book by early April.
Best month for zero-pressure scheduling. Batteries charged and held on a tender until launch week. No wait list.
Peak demand. Book two weeks ahead. This is the highest-volume month of the year.
Memorial Day rush. Book by May 1 to guarantee water before the holiday weekend.
Late-bloomers welcome. Summerization at any time is better than no summerization.
Pricing is transparent and based on engine type. No surprise add-ons, no trip fees inside the Spokane metro and CdA corridor. Fluids and filters billed at cost.
Pricing includes battery service, fuel system inspection, fluid checks, impeller inspection, full system test, and a complete run-up. If we find a problem during summerization, you get a quote before any work beyond the base scope.

Inland Northwest coverage, no trip fees inside the core radius.
If you trailer to Lake Roosevelt, Long Lake, Lake Pend Oreille, or the Spokane River access points, we can summerize at your home first or meet you at the launch the morning of your first trip.
Spokane Boat Repair has been the region's trusted mobile marine service for years. Every summerization is done by a factory-trained marine tech, fully insured, with the same diagnostic and parts-sourcing capability as a shop — just without the tow bill.
Boat summerization is the process of bringing a boat out of winter storage and getting it ready for the season. It covers battery service, fuel system check, fluid inspection, impeller check, cooling system test, electrical verification, and a full engine run-up. Industry technicians call the same service "spring commissioning" or "de-winterization." It's the reverse of the winterization you did (or should have done) in the fall.
Outboards run $200 to $350. Stern drives run $300 to $500. Inboards run $350 to $600. Twin-engine boats run $450 to $800. Pricing is all-in for the base service. No trip fees inside the Spokane / Coeur d'Alene corridor. Fluids, filters, and parts billed at cost.
Yes — and arguably more than an owner who didn't, because a partial or DIY winterization has more unknowns. We verify that stabilizer held, check for water intrusion in the fuel and lower unit, and confirm every system is actually ready to launch. Most spring no-starts are caused by a winterization step that got skipped or done incompletely.
Mid-March through mid-April is ideal. You want the boat ready before the first warm weekend, but not so early that batteries sit charged for weeks. April is our peak month — book two weeks in advance. If you want guaranteed water access for Memorial Day, book by early May.
Yes. Mobile summerization is most of what we do. We come to your driveway, garage, storage yard, or marina slip. All we need is access to the boat and, if possible, a hose connection for cooling system run-up. If no hose is available, we bring our own flushing rig.
You get a written quote before any work outside the base scope. Nothing gets repaired without your approval. Common spring finds: dead battery, bad impeller, contaminated gear oil (water intrusion), stale fuel, cracked hoses, or a carburetor that gummed up despite stabilizer. All fixable — most of them same day.
Most single-engine outboards finish in 1.5 to 2 hours. Stern drives and inboards run 2 to 3 hours. Twin-engine boats run 3 to 4 hours. You don't need to be present the whole time.
Yes. Summerization on inboard wake and ski boats (Malibu, MasterCraft, Supra, Moomba, Axis, Centurion, Tige) is a core part of our business. Indmar, PCM, and Ilmor engines are all supported.
Yes. We call this a "neglect start" summerization. It takes longer and sometimes uncovers real problems (phase-separated fuel, cracked block from freeze damage, failed seals from moisture). We can diagnose on-site and tell you whether it's a simple summerization or whether deeper repair is needed before launch.
Yes. We offer a $125 to $175 pre-launch inspection that verifies your DIY work and does a full run-up. If we find anything that needs addressing, the diagnostic cost rolls into the repair. Most owners who try this end up booking the full service the next year — it's cheaper per boat-hour on the water.
Our April calendar fills fast. If you want guaranteed water access for the first 75-degree Saturday, call today.
