Important – Electrical Part

A faulty starter solenoid may cause:

Starter motor not operating
Clicking when turning the key
Intermittent starting
Starter operating occasionally
No-crank condition

These symptoms can also be caused by the battery, starter motor, ignition switch, earth connection, wiring or terminals.

Electrical parts that have been fitted or installed cannot be returned unless faulty.

Buyer Responsibility

It is the buyer's responsibility to confirm compatibility before purchase.

Please check your:

Engine HP
Engine model
Serial number
Original starter solenoid part number

If the relay looks the same as yours, this does not always mean it is the correct part for your outboard.

If you are unsure, contact SSI Marine with your engine model and serial number and we will be happy to help.
