Aftermarket Mercury 50-60HP 3-Cylinder (0D000750-0G589999) Service Kit | Sawley's Select Marine Parts

🔧 Product Description

Aftermarket major service kit for selected Mercury and Mariner 50HP, 55HP and 60HP inline three-cylinder carburetted two-stroke outboards within serial range 0D000750-0G589999. This package is configured for the standard small-gearcase engine family using the 47-19453T impeller system; it is not the later 821354A2 pump family and is not suitable for BigFoot or large-gearcase models.

The serial span covers two commonly catalogued production groups—0D000750-0G290584 and 0G290585-0G589999—while retaining the same core three-cylinder service configuration. Engine serial number, gearbox type and existing water-pump arrangement must all be checked before ordering.

🔌 Function

Provides the principal ignition, fuel, thermostat, gearcase-sealing and water-pump consumables required for a comprehensive scheduled service. Replacing these items helps maintain reliable starting, correct combustion, fuel flow, cooling-water delivery and gearcase oil sealing.

Common signs service is due include:

• Difficult starting, misfire or fouled spark plugs

• Restricted fuel flow or deteriorated fuel-filter media

• Engine running too cold, overheating or unstable operating temperature

• Weak tell-tale flow, elevated cylinder-head temperature or damaged impeller vanes

• Milky gear oil or seepage around drain/fill screws caused by reused sealing washers

📦 Condition

• Brand-new aftermarket service kit

• Supplied with new, unused service components

• Individual component brands may vary according to current supply, while matching the listed OEM references

• Confirm engine serial number, standard gearbox and existing pump design before installation
