The starter for a Chrysler 85 outboard motor is a critical mechanical and electrical component designed to initiate engine operation by converting electrical energy into the rotational force needed to crank the engine. Chrysler’s 85HP outboards, commonly used in mid-sized boats from the 1960s to 1980s, require a durable starter that can withstand marine environments while delivering reliable starting power. The starter motor system for these engines balances rugged construction with precise engineering to ensure consistent performance on the water.

Design and Marine Specifications


The starter for a Chrysler 85 outboard typically features:

 

  • High-Torque DC Motor: Engineered for 12V electrical systems, with a power output optimized to crank the 85HP engine’s flywheel (typically 136–152 teeth).

  • Corrosion-Resistant Construction: Stainless steel fasteners, sealed electrical connections, and a cast aluminum housing to combat saltwater and humidity.

  • Integrated Solenoid: A weatherproof solenoid that engages the starter gear with the flywheel when triggered by the boat’s ignition switch, ensuring reliable engagement in wet conditions.

  • Overrunning Clutch: A built-in clutch mechanism that prevents the starter from being driven by the engine after startup, protecting it from damage.


Placement and Installation


On most Chrysler 85 outboards:

 

  1. Location: The starter is mounted on the lower starboard side of the powerhead, adjacent to the flywheel housing, accessible by removing the engine cowling.

  2. Wiring:

    • Connect the positive battery cable to the solenoid’s main terminal (marked “BAT”).

    • Attach the ignition switch wire to the solenoid’s control terminal (marked “S” or “IGN”), often via a waterproof connector.



  3. Mounting: Secured with vibration-dampening brackets and stainless steel bolts, torqued to Chrysler’s specifications (typically 18–22 ft-lbs) to withstand engine movement.


Maintenance and Vintage Marine Tips



  • Routine Inspections:

    • Clean salt deposits from terminals with a wire brush and apply dielectric grease to prevent corrosion.

    • Check the starter gear and flywheel for wear, as saltwater can accelerate metal degradation.



  • Winterization: Before storing, inspect the starter for loose connections and disconnect the battery to avoid corrosion.

  • Brush Replacement: For starters with serviceable brushes, replace them if worn below 1/4 inch to maintain electrical conductivity.


Troubleshooting Common Issues



  1. No Engagement:

    • Verify battery charge (12V systems require ≥12.4V at rest).

    • Check for blown fuses, a faulty ignition switch, or corroded wiring. A clicking solenoid may indicate a weak battery or damaged contacts.



  2. Grinding Noise:

    • Worn starter or flywheel gears; inspect for notches and replace components if damaged.

    • Misalignment due to loose mounting bolts; retighten to specification.



  3. Intermittent Starting:

    • Faulty solenoid or wiring shorts; test continuity with a multimeter and replace faulty parts.

    • A weak or failing clutch in the starter drive, requiring assembly replacement.
