20-Hour Break-In Service
A 20-hour check is one of the most important services you can do for a brand-new outboard. After the initial break-in period, every major manufacturer requires this inspection to keep the factory warranty intact — and to catch any issues before they become failures. Fluid change, general inspection, and the peace of mind that your investment is protected.
What Is the 20-Hour Check?
Most outboard manufacturers — Suzuki included — require an inspection and oil change at 20 operating hours. We perform the manufacturer-specified service exactly as written, and document it for your records.
- Engine oil and filter change with manufacturer-specified oil
- Lower unit gear lube drain and inspection
- Anode and zinc condition check
- Cooling system and fuel system inspection
- Idle, throttle, and shift cable adjustment
- Service documented for warranty and resale records
Why the 20-Hour Check Matters
- Required by most outboard manufacturers to maintain factory warranty
- Catches break-in wear issues before they become failures
- Metal particles from break-in are flushed out with the first oil change
- Confirms all rigging, controls, and systems are dialed in correctly
- Creates documented service history that protects resale value
