Engine Maintenance guides
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.
Read guide →Check engine and lower-unit oil color monthly
Oil color tells you more than the hour meter — milky oil means water intrusion; metallic glitter means internal wear.
Read guide →Inspect prop, skeg, and zincs every month in season
Dings, fishing line, and depleted anodes are cheap to fix early and expensive when ignored.
Read guide →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.
