Engine parts for Singapore harbourcraft

A practical guide to engine service parts, the details needed for identification and examples of engines documented on Singapore harbour craft.

Start with the part you need

For a routine service, a breakdown or an overhaul enquiry, identifying the existing engine and component is the first step. A clear nameplate photo and an old part number can save several rounds of messages.

Brands relevant to the local harbourcraft fleet

A July 2023 NTU/MESD report, using MPA’s 2021 harbourcraft database, documented Cummins, Mitsubishi, Yanmar, Weichai and Caterpillar among the engine brands in the fleet. Other brands in the study included MAN, Daihatsu, Shanghai Diesel, Volvo, MTU and Wärtsilä.

The study describes engines recorded in 2021. For a parts enquiry, send the complete model and serial number from your installed engine, even if its brand appears in this list.

Examples of engines documented locally

The following models appear in published operator specifications. Use your own engine’s complete designation and serial number for parts matching.

Why the engine family is only a starting point

Engines with similar names can have different ratings, build arrangements and fitted accessories. The filter housing, seawater pump or alternator may also carry its own identification. Include that component’s details when asking for a replacement.

For a service-parts package, send the required items or workshop list. We can check the references and quantities before quoting. Do not treat a kit described for an engine family as automatically correct for your engine.
