Important – Please Check Compatibility

Mercury and Mariner produced different 25 HP engine generations, and not every 25 HP model uses this starter motor.

Please do not order by horsepower or appearance alone.

Before purchasing, please check:

Engine is Mercury or Mariner
Engine is 25 HP
Engine is 4 Stroke
Engine is the applicable 2-cylinder version
Engine serial number
Original starter motor part number
9-tooth starter drive
Mounting points and electrical connections

Your engine should correspond with one of the Mercury / Mariner starter motor part numbers listed above.

If the starter motor looks the same as yours, this does not always mean it is the correct one for your outboard.

If you are unsure, please send SSI Marine your engine model and serial number before ordering and our technical team will be happy to check compatibility.
