What it is

The 100-hour service is the most common scheduled maintenance visit for actively used outboards in Tampa Bay. It includes all 50-hour items plus impeller inspection, thermostat operation check, extended rigging review, and a documented safety systems assessment — completed mobile at your vessel.

Why you need it

By 100 hours, water pump impellers begin to lose efficiency, thermostats can stick, and salt exposure accelerates corrosion on hardware you don't see from the helm. Skipping this interval is one of the most common reasons owners experience overheating, hard shifts, or sudden loss of power mid-season.

Who it's for

Weekend anglers, family cruisers, and anyone logging regular hours from spring through fall. Ideal for owners who want a single annual visit that covers both routine fluids and preventive inspection.

Common questions

Is the 100-hour service enough for once a year?

For many Tampa Bay owners who run 75–125 hours per year, yes — the 100-hour interval is the right annual anchor. High-hour or commercial-style use may require 200-hour protocols sooner.

What's in the photo report?

We document fluid condition, wear items, corrosion, and any recommendations — texted and emailed the same day so you have a permanent record tied to your vessel.

Can I bundle a detail with this visit?

Yes. Our Service + Detail Combo packages scheduled maintenance and premium detailing in one dock visit — see pricing or ask when you book.

Owner tips for this service

DIY habits that complement professional 100-Hour Outboard Service — and when to book a pro instead.

Engine Maintenance

Flush your outboard after every saltwater run

Salt left in cooling passages accelerates corrosion and can restrict water flow long before you see an overheat alarm.

No regrets: If the engine touched saltwater today, flush it today — not next weekend.

Engine Maintenance

Treat your hour meter like an odometer — log every interval

Manufacturer service intervals are hour-based. Skipping a window voids warranty coverage and stacks deferred work into one bill.

No regrets: The 100-hour visit is the one most Florida weekenders should anchor their year on.

Fuel System

Drain and inspect your fuel/water separator monthly

The bowl tells you what's entering your engine before damage happens.

No regrets: If you see water in the bowl, stop running and diagnose — don't just drain and hope.
