🚤 Compatibility

Commonly used on:

• Evinrude six-cylinder cross-flow outboards

• Johnson six-cylinder cross-flow outboards

• High-output V6 capacitor-discharge ignition systems

Typically suits:

• 150HP:

• Selected 1989-1991 V6 cross-flow engines

• 155HP:

• Selected 1989-1992 V6 cross-flow engines

• 175HP:

• Selected 1989-1991 big-bore V6 cross-flow engines

• Engine Configuration: Six-cylinder V6 two-stroke

• Ignition Type: Rotating timer-base capacitor-discharge ignition

Important fitment note:

• Confirm the original number and engine model before ordering.

• V6 cross-flow and V6 loop-charged timer bases are not interchangeable.

• Compare connector pin count, wire colours and mounting diameter.

• The stator, power pack and flywheel are included only when shown or stated.

🔌 Function

The timer base produces six-cylinder crankshaft-position signals for the ignition power pack.

Its mechanical rotation advances ignition timing as throttle position and engine speed increase.

Common signs of failure:

• Spark loss on one or more cylinder pairs

• Engine runs on only part of the cylinder bank

• Difficult starting or backfiring

• Misfire under load

• Spark fails when the engine warms

• Incorrect maximum timing

• Engine will not achieve full rpm

• Trigger resistance or peak output is outside specification

• Cracked wiring or corroded terminals

Recommended checks before installation:

• Test every trigger circuit individually

• Compare the connector and wiring with the original

• Inspect the timer-base bearing surface

• Confirm free advance and return movement

• Test both power packs where applicable

• Check stator output and ignition-coil operation

• Perform the factory timing and synchronisation procedure

📦 Condition

• Genuine OMC, Evinrude or Johnson used part

• Pre-owned electrical component

• Cosmetic wear, wire ageing and light corrosion may be present

• Electrical testing before installation is strongly recommended

• Included components are limited to those shown or described

• Supplied in protective or equivalent packaging
