🔌 Function

The service kit groups the routine ignition, lubrication, fuel-system, cooling-system and gearcase consumables required for a major scheduled service. Replacing the listed components helps maintain reliable starting, correct operating temperature, clean fuel delivery, adequate cooling-water flow and secure engine and gearcase sealing.

Common signs service is due:

• Hard starting, rough idle or misfire from worn or fouled spark plugs

• Restricted fuel delivery or unstable engine speed from a contaminated filter

• Engine temperature runs high because the thermostat or water pump is deteriorated

• Low oil pressure, dirty engine oil or a restricted oil filter on four-stroke engines

• Water or lubricant leakage from reused drain-plug seals

• Reduced cooling-water discharge or damaged impeller vanes

📦 Condition

• Brand new aftermarket service kit

• New and unused components

• Supplied in manufacturer or equivalent protective packaging
