Boat Service

Boats break on the best weekends by ancient law. Regular service by techs who care is how you repeal it.

Service we provide

  • Outboard and sterndrive engine service to factory schedules
  • Spring commissioning - fluids, filters, props and systems checks before splash
  • Winterization done thoroughly - the cheap insurance against cracked blocks
  • Shrink wrapping and off-season storage prep
  • Impellers, lower units, fuel systems and electrical gremlins
  • Pre-purchase inspections before you buy someone's deferred maintenance

Winterize like the block depends on it

Every spring we meet engines killed by shortcut winterizations - water left in a passage, fuel untreated, batteries abandoned. Ours follows the full factory checklist: drained, flushed with antifreeze where specified, fogged, fuel stabilized and batteries managed. It's a modest bill against a four-figure block - the easiest math in boating.

Spring commissioning is the mirror image: everything checked at the dock, so the first launch is a boat ride and not a diagnostic session.

Common questions

When should I winterize?

Before the first hard freeze, no exceptions - one cold snap with water in the block is all it takes. Book early; the calendar fills fast when the forecast turns.

Do you come to the boat?

Yes - dockside and driveway service for most work. Bigger jobs come to the shop.

How often does an outboard need service?

Annually or per the hour interval, whichever lands first. Impellers on their schedule too - a cheap part that protects an expensive engine.

Boats should break records, not weekends.
