Important – Please Check Compatibility
Mercury and Mariner used different starter motors across engines with the same horsepower.
Please do not order by horsepower or appearance alone.
Before purchasing, please check:
-
Mercury or Mariner engine
-
Engine horsepower
-
Engine model
-
Engine year
-
Engine serial number
-
4-stroke application
-
Carburettor engine
-
Original starter motor part number
-
13-tooth starter drive
-
Mounting points and electrical connections
Your engine should correspond with:
50-804312T1 / 50-8M0065220
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 serial number before ordering and our technical team will be happy to check compatibility.
