🔌 Function

The starter provides the cranking speed required for electronic fuel injection, direct injection and supercharged outboard engines to establish fuel pressure, ignition synchronisation and combustion.

Common signs of failure:

• No crank despite correct battery and relay operation

• Slow cranking that causes low-voltage EFI or PCM faults

• Solenoid clicks without pinion engagement

• Starter operates intermittently when hot

• Grinding, pinion kick-out or damaged flywheel teeth

📦 Condition

• Supplied as a complete replacement assembly

• Verify the full serial number and original 853329/892339 starter family before installation
