- Transportation Hassles: Hauling a boat to a repair shop can be difficult and time-consuming, especially for those without a trailer or access to a launch ramp.

Consequences of Skipping Routine Maintenance
- Neglecting your outboard motor’s scheduled maintenance can lead to serious mechanical failures, including:
- Corroded Components: Saltwater exposure without proper flushing leads to corrosion, damaging critical parts like the cooling system and lower unit.
- Overheating Issues: A worn-out water pump impeller can fail, causing the engine to overheat and suffer severe damage.
- Reduced Fuel Efficiency & Power Loss: Clogged fuel injectors, dirty spark plugs, or old fuel filters can make your motor run rough and less efficiently.
- Gearcase Damage: Not changing lower unit oil can result in metal shavings and water contamination, leading to a catastrophic gearbox failure.
Seattle’s Saltwater Environment: Extra Precautions You Should Take
Seattle boaters face additional challenges due to the region’s saltwater conditions.
To combat premature wear and corrosion, we recommend:
- Flushing Your Outboard After Every Use: Running fresh water through the cooling system removes salt deposits and prevents buildup.
- Using Corrosion Inhibitor Sprays: Applying anti-corrosion spray on electrical connections, powerheads, and metal surfaces helps extend the life of your outboard.
- Inspecting Anodes Frequently: Sacrificial anodes protect your engine from electrolysis and should be replaced when they are more than 50% depleted.
