What's Included

⚠️ Important Compatibility Warning

This power pack is for selected 2-cylinder engines using the 2-wire trigger ignition system.

It does NOT fit every Johnson / Evinrude 4–60 HP engine from 1977–1984.

Before ordering, please check:

• Engine horsepower

• Engine model number

• Model year

• Original power pack part number

• Electrical connectors / wiring

• 2-wire trigger configuration

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

If unsure, send SSI Marine your engine model number + horsepower + year if known and we will help check compatibility.

Buyer Responsibility

It is the buyer's responsibility to confirm compatibility before purchasing.

OEM part numbers are used for identification and reference purposes only.

Correct diagnosis is recommended before replacing a power pack, as stator, trigger/timer base, ignition coil, kill circuit, wiring or other ignition faults can produce similar symptoms.
