Full model list at the end of this description.

⚙️ Key Features

  • 24V electrical system
  • Rated output: 5.0 kW
  • D4/D6 marine diesel application
  • High-torque reduction-drive construction
  • Not interchangeable with 12V starter 21423488

🔌 Function

The starter draws power from the 24V battery system and supplies the cranking torque required to start the high-compression diesel engine.

⚠️ Common Signs of Failure

  • No crank or intermittent cranking
  • Slow cranking
  • Solenoid clicks without motor rotation
  • Grinding or pinion engagement noise
  • Starter remains engaged
  • Excess current draw or overheated cables

🛠️ Service Notes

  • Confirm the installation is 24V before fitting; this part is not interchangeable with the 12V starter 21423488.
  • Check battery and ground cable condition and clean terminal connections before fitting, since excess current draw and overheated cables are listed as failure signs of a poor circuit elsewhere.
  • Tighten the mounting bolts evenly so the starter pinion aligns correctly with the flywheel ring gear.
