OEM reference numbers

Use these original-equipment numbers only as an identification guide. The number on the removed starter or in the engine parts catalogue should match:

Mercury / Mariner 50-853805T01, 50-853805T03, 50-8M0147039
Tohatsu / Nissan 3C8-76010-1, 3C8-76010-100
Suzuki 31100-94400, 31100-94401, 31100-94402, 31100-96310, 31100-96311

Engine compatibility

Brand Application guide Essential check
Mercury / Mariner Selected outboards using the 50-853805 starter family Match OEM number and serial range
Tohatsu / Nissan Selected 30–40 HP two-stroke engines using the 3C8 starter family Match 3C8 reference, voltage, teeth and mounting
Suzuki Selected DT-series 30–40 HP two-stroke engines Match the 31100 OEM number and engine model

Important: horsepower alone is not sufficient to confirm fitment. Engines of the same power can use different starters depending on model, year, production market and serial number.

Check before ordering

  1. Read the OEM number from the existing starter or the engine parts catalogue.
  2. Confirm a 12 V system, 9-tooth pinion and CCW rotation.
  3. Compare the mounting points, electrical terminal position and overall shape with the photographs.
  4. Check the full engine model and serial number. If uncertain, send these details before purchase.

What is included

One starter motor, supplied as shown. Mounting bolts, starter relay/solenoid, wiring and installation tools are not included unless visible in the product images.

Frequently asked questions

Is this a genuine Mercury, Tohatsu or Suzuki part?

No. It is a new aftermarket replacement designed for engines using the listed OEM starter references.

Will it fit every 30 HP or 40 HP outboard?

No. Fitment depends on the engine model, year, serial range, original part number and starter configuration.

How can I confirm compatibility?

Match the OEM number first, then confirm voltage, rotation, pinion teeth, mounting points and electrical terminal position.

Does the starter relay or solenoid come with it?

No separate relay or solenoid is included unless it is clearly shown in the listing photographs.

Need a fitment check? Send the engine make, complete model, year/serial number and the reference stamped on the old starter before ordering.
