🚤 Compatibility

Commonly used on:

• Evinrude V4 cross-flow outboards

• Johnson V4 cross-flow outboards

• Early capacitor-discharge ignition systems

Typically suits selected 1973-1979:

• 85HP

• 115HP

• 135HP

• 140HP

• Engine Configuration: Four-cylinder V4 two-stroke

• Application Family: Early cross-flow ignition

Important fitment note:

• Confirm the service number and not only casting number 385500.

• Check wire colours, connector type, timer-base diameter and linkage.

• Later V4 cross-flow and loop-charged timer bases are not interchangeable.

🔌 Function

The timer-base sensors generate crankshaft-position pulses for the ignition power pack.

The assembly rotates with the spark-advance linkage as the throttle is opened.

Common signs of failure:

• No spark on one or more cylinders

• Intermittent spark loss

• Engine backfires during starting

• Spark disappears when warm

• Incorrect ignition timing

• Engine will not reach full advance

• Trigger output is below specification

• Cracked wiring

• Timer base binds or has excessive play

Recommended checks before installation:

• Confirm 0581300 / 581300

• Inspect casting number 385500 only as secondary identification

• Test trigger resistance and peak output

• Check the stator, power pack and coils

• Inspect the timer-base bearing surface

• Set ignition timing and synchronisation after installation

📦 Condition

• Genuine OMC, Evinrude or Johnson used part

• Pre-owned electrical component

• Wire ageing, marks and oxidation may be present

• Electrical testing before installation is strongly recommended

• Supplied in protective or equivalent packaging
