Product Details
This aftermarket starter solenoid relay is designed for selected Mercury Mariner and Chrysler Force outboard applications. The company fitment records specifically list Mercury Mariner 75 HP three-cylinder outboards with serial number G127500 and newer, early-model Mercury Mariner applications from 35 HP through 150 HP, and Force outboards from 35 HP through 150 HP.
Use the original solenoid, engine model, and complete serial number to confirm the match before ordering. Fitment varies by engine configuration and production range; the general horsepower range alone is not sufficient for identification.

Troubleshooting & FAQ
What engines are specifically documented for this relay?
The company records specifically identify Mercury Mariner 75 HP three-cylinder outboards with serial number G127500 and newer. They also identify early-model Mercury Mariner applications from 35 HP through 150 HP and Chrysler Force outboards from 35 HP through 150 HP. Confirm the complete model and serial number before ordering.
Does this relay fit every Mercury or Force outboard in the stated horsepower range?
No. Horsepower is only one part of fitment. Model generation, cylinder configuration, serial number, terminal layout, and mounting arrangement must also match the original solenoid.
Which OEM numbers are associated with this relay?
The documented OEM references are 89-817109A1, 89-817109A2, 89-817109A3, 803822T, 817109A1, 817109A2, and 817109A3. Force references listed for the product include F460917, F460917-1, FK460917, and FK616917.
Which aftermarket references are listed?
The available company data lists Sierra Marine 18-5834, Sierra Marine 18-5835, and Mallory Marine 9-15117 as aftermarket references.
Is this a kit?
No. This listing is for one individual starter solenoid relay. Wiring, mounting hardware, and other electrical components are not included unless shown or stated separately.
What are common symptoms of a failing starter solenoid?
Possible symptoms include a click without starter engagement, intermittent cranking, or no response when the starting switch is operated. Battery condition, cables, grounds, switches, and the starter motor should also be tested before replacing the solenoid.
Is this an OEM component?
No. This is an aftermarket replacement relay intended for the documented Mercury Mariner and Chrysler Force applications.
