FAQ

Q1: Is this starter motor a direct bolt-on for my Yanmar 3TNE84 engine?
Yes, this unit is designed as a direct OEM replacement. It matches the original mounting flange, 2-bolt pattern, and 11-tooth drive gear. No modifications or adapters are required. Simply disconnect the battery, remove the old unit, install the new one, and reconnect the electrical connections.

Check the existing starter motor for a stamped or labeled part number. If it is one of the cross-referenced numbers listed above (e.g., 171008-77011), it is compatible. If the number is different, please contact us with your engine model (3TNE84) and the number on your current starter. We can cross-reference it within 24 hours.

Q3: What maintenance is required for this starter motor?
This is a sealed, maintenance-free unit under normal operating conditions. For extended life: ensure the battery provides adequate voltage (12.6V+), keep electrical connections clean and tight, and avoid prolonged cranking (over 10 seconds at a time). In dusty environments, periodic cleaning of the exterior can prevent debris buildup. If starting issues occur, check the battery, wiring, and engine ground first before replacing the starter.
