⚙️ Suzuki Outboard Maintenance Tips

The following are some Suzuki tips for maintaining your engine at optimum condition:

1. Flush After Every Use (Especially Saltwater)

Even premium marine engines need protection. Flushing your outboard cleans out salt, sand, and sediment that could be in cooling passages.

2. Use Only Genuine Suzuki Parts

Third-party spark plugs, oil filters, and gaskets may not be of Suzuki quality. Use only genuine parts – we carry them too!

3. Store Seasonally Correctly

Fog the engine, stabilize the fuel, and drain the battery when you winterize or store for prolonged periods.

4. Record Keeping

Maintain a history of the date, engine hours, and services done. This will benefit resale, warranty repair, and troubleshooting in the future.
