Yanmar 2QM15 Marine Inboard Diesel Engine 15HP
The Yanmar 2QM15 15HP marine inboard diesel engine is a 662 cc, two-cylinder diesel for sailboat auxiliary propulsion and small-vessel replacement projects. Part of the Yanmar QM Series, it combines indirect fuel injection, seawater cooling and a conventional marine reduction gearbox.
MSS Motorsports UG offers the Yanmar 2QM15 for buyers assessing a replacement engine or planning a compatible inboard installation. Request current availability, condition details and a quotation for the package your boat requires.
A Replacement Option for Existing QM Installations
For a vessel already fitted with a Yanmar 2QM15 15HP, evaluating the same model allows your installer to compare the proposed engine with the existing mounts, shaft coupling, exhaust and controls.
Its suitability depends on the boat’s displacement, propulsion requirements and installation layout. A clearly specified engine and gearbox combination helps establish the equipment and installation work needed before purchase.

Gearbox Ratio and Shaft-Drive Integration
For a Yanmar 2QM15 15HP engine and gearbox package, confirm the required reduction ratio before ordering. The 2QM15 and 2QM15G designations correspond to different original forward ratios, so the complete identification matters when matching a replacement to an existing propeller and shaft.
If you intend to retain your gearbox, provide its model, ratio and identification-plate photograph. Your installer should also review coupling dimensions, shaft alignment, engine-bed compatibility and control connections.
For another Yanmar option, compare the Yanmar 2GM20 marine inboard diesel engine, with power and installation suitability assessed for your vessel.
Cooling, Condition and Included Equipment
The standard Yanmar 2QM15 15HP uses direct seawater cooling. When evaluating an earlier-generation engine, inspect the cooling passages, pump, thermostat, exhaust components and corrosion protection alongside its running condition.
Request the engine serial number, recorded operating hours and any available service, inspection or refurbishment records. The quotation should identify whether the gearbox, instrument panel, wiring, mounts and other accessories are included, together with any applicable warranty terms.
For documentation and parts enquiries, use the full model and serial number. The official Yanmar service FAQs explain how to obtain manuals for non-current engines.
