What it is

Spring commissioning reverses winter layup and prepares your vessel for active season. Full Throttle Marine de-winterizes the engine, verifies fuel and electrical systems, performs start-up and test runs, and delivers a launch-ready sign-off at your dock.

Why you need it

After months idle, fuel degrades, batteries weaken, and corrosion advances in places you cannot see from the helm. Starting an engine without commissioning risks immediate damage and ruins the first weekend of the season. Commissioning confirms systems are safe before you load family and gear aboard.

Who it's for

Owners returning from winter storage, seasonal residents back for summer, and anyone who winterized with us or elsewhere and wants a professional launch checklist.

Common questions

I didn't winterize with FTM — can you still commission?

Yes. We commission vessels regardless of who performed winterization. We'll assess condition on arrival and quote any additional work before proceeding.

When should I schedule commissioning?

Book four to six weeks before your target launch date. March and April fill quickly across Tampa Bay.

Does commissioning include a full 100-hour service?

Commissioning is launch prep, not a full interval service. If your hours require a 100- or 200-hour visit, we can combine appointments in one dock day.

Owner tips for this service

DIY habits that complement professional Spring Commissioning — and when to book a pro instead.

Fuel System

Use ethanol-safe fuel and stabilize before layup

E10 absorbs moisture in humid climates. Phase-separated fuel destroys injectors and carburetors.

No regrets: Fuel older than 30 days in a vented tank deserves stabilizer — or a fresh fill before storage.

Fuel System

Prime the fuel system correctly after long idle periods

Dry starts after storage starve the fuel pump and can air-lock the system.

No regrets: Never crank endlessly on a no-start — fix fuel delivery first.

Full DIY guide →

Electronics & Electrical

Maintain batteries on a float schedule during idle weeks

Sulfated batteries cause no-starts, false alarm codes, and weak sonar returns.

No regrets: A $40 maintainer beats a $200 tow because you cranked on a dead battery.
