Before selecting parts

Identify the engine you have

Use the complete identification to select the correct generation, diagram and replacement part.

3GM30 / 3GM30F cooling

3GM30 is directly seawater cooled; the F version uses freshwater heat-exchanger cooling. The two cooling configurations require their own assembly selection.

Exact suffix & generation

The 0.954-litre family includes separately catalogued installation variants. Earlier 3GM and newer 3YM engines are distinct model families.

Gear or saildrive

Identify the actual marine gear or saildrive from its own plate. An abbreviated boat specification does not establish the engine cooling suffix.

Do not use a newer 3YM engine application as proof of 3GM30 fitment.

Send the complete engine-plate details and clear old-part photos. Match the installed fuel and cooling equipment, and include the separate drive or marine-gear plate when asking about those assemblies.
