The Yanmar 2YM15 14HP inboard diesel engine is a compact mechanical marine diesel designed for smaller sailboats and pleasure craft. With a 0.57-liter, two-cylinder configuration, natural aspiration and a rated output of 10 kW / 14 MHP at 3,600 rpm, the 2YM15 is built around straightforward mechanical operation and efficient marine propulsion. Yanmar lists the engine as part of its YM series for smaller sailing and recreational vessels, making it a practical option for repower projects where compact dimensions, dependable diesel power and straightforward controls are important.
The current Yanmar specification lists a 12V 125A alternator, fresh-water cooling, indirect injection with an in-line pump and a dry engine weight of approximately 103 kg (227 lb) without gear. The published dimensions are 613 × 463 × 600 mm, although Yanmar notes that dimensions can vary with the selected marine gear and exhaust elbow. Before ordering, confirm the required transmission or saildrive, installation dimensions, controls and mounting arrangement for the vessel.
The 2YM15 is designed for the smaller end of Yanmar’s mechanical marine engine range. Yanmar’s current YM series identifies the 2YM15 as a 14 MHP engine with a rated speed of 3,600 rpm. Its compact two-cylinder layout provides a marine diesel power solution for vessels where engine-room space and installation weight need to be considered alongside propulsion requirements.
The engine uses a naturally aspirated combustion system rather than a turbocharger. This straightforward configuration is well suited to buyers looking for a compact mechanical diesel with conventional marine-engine architecture. The manufacturer specifies indirect injection and an in-line pump, while mechanical controls keep the engine interface familiar for traditional marine installations.

Yanmar notes that its published dimensions depend on the selected configuration. The manufacturer’s current specification states that length includes the KM2P-1 marine gear and height includes a U-type elbow for the applicable configuration, so the exact installation envelope should be checked against the selected transmission and exhaust arrangement.
The Yanmar 2YM15 uses a fresh-water cooling system with a heat exchanger. This is an important consideration for marine installations because the cooling arrangement is designed around the requirements of a dedicated marine propulsion engine. Yanmar’s published specifications identify the engine as a vertical, water-cooled four-stroke diesel with flexible mounting.
Installation should be planned around the complete propulsion package rather than the bare engine alone. Check the engine-bed dimensions, shaft or saildrive configuration, exhaust routing, cooling connections, fuel system, control cables, electrical connections and available service access before committing to a repower.
The current Yanmar specification lists a 12V 125A alternator for the 2YM15. This charging capacity can support the vessel’s 12V electrical system while the engine is operating, subject to the actual electrical loads, battery-bank configuration and installation.
When replacing an older marine diesel, evaluate the alternator output together with the vessel’s batteries, charging equipment, navigation electronics, lighting, pumps and other onboard loads. The engine’s charging capability should be treated as one part of the complete electrical system rather than as a standalone measure of vessel electrical capacity.
The Yanmar 2YM15 uses mechanical controls. This makes the engine suitable for installations where conventional throttle and shift arrangements are preferred. Yanmar also lists compatible B20 and C30 panel options and accessories such as extension harnesses, dual-station harnesses and a TFX sidemount control head.
Available equipment depends on the exact engine package and installation. Confirm which panel, control head, harnesses and transmission or saildrive are included with the unit before ordering if you are replacing an existing engine.
Yanmar publishes the 2YM15 with both KM2P-1 marine gear and SD25 saildrive configurations. The correct drive arrangement depends on the vessel’s propulsion architecture. A shaft-drive installation and a saildrive installation have different mounting, alignment, clearance and propeller requirements.
If the 2YM15 is being purchased for a repower, compare the existing engine’s transmission ratio, shaft alignment, propeller requirements and engine-bed arrangement with the selected Yanmar package. Do not assume that the existing transmission or propeller can be reused without confirming compatibility.
The 2YM15 is intended for smaller sailboats and pleasure craft. Yanmar describes the YM series as a range of mechanical engines for smaller sailboats and pleasure craft, with the 2YM15 positioned as the 14 MHP model. Its compact two-cylinder format makes it particularly relevant when a vessel needs diesel propulsion without moving to a larger engine platform.
Typical buying considerations include vessel displacement, hull type, required cruising speed, existing propulsion arrangement, shaft or saildrive configuration, engine-bed dimensions and available engine-room space. Final engine selection should be based on the vessel manufacturer’s requirements and the complete propulsion system.
Before installing a Yanmar 2YM15, measure the available engine-room space and compare it with the manufacturer’s dimensions for the exact gear and exhaust configuration. Also confirm access for routine maintenance, including oil service, filters, cooling-system service, belts and electrical components.
For a repower, the most important compatibility checks include the engine mounts, transmission or saildrive, shaft alignment, propeller, exhaust system, cooling connections, fuel system, electrical wiring and control arrangement. A marine technician should confirm these interfaces before installation.
The Yanmar 2YM15 combines a compact two-cylinder design with a 14 MHP rated output, natural aspiration, mechanical controls and a 12V 125A alternator. Its published 103 kg dry weight without gear and compact dimensions can be useful when planning a smaller-vessel repower, while the availability of KM2P-1 and SD25 configurations provides flexibility for different propulsion layouts.
For buyers comparing smaller marine diesel engines, the most useful specifications to compare are rated power, engine speed, displacement, weight, dimensions, cooling system, alternator output, transmission compatibility and control type. Reviewing those factors together helps determine whether the 2YM15 is appropriate for the intended vessel and installation.

The current Yanmar specification lists the 2YM15 at 10 kW / 14 MHP rated output and 3,600 rpm. Yanmar’s documentation also distinguishes between rated output and continuous-power figures, so the exact operating specification should be checked for the intended installation.
The 2YM15 is a two-cylinder diesel engine. Yanmar specifies a 70 mm bore and 74 mm stroke with 0.57 L total displacement.
Yes. Yanmar lists the 2YM15 as naturally aspirated. It uses indirect injection with an in-line pump rather than a turbocharged air system.
Yanmar currently lists approximately 103 kg (227 lb) dry weight without gear. The complete installed package will weigh more once the selected marine gear or saildrive, mounts, fluids and associated components are included.
The current Yanmar specification lists a 12V 125A alternator. Actual charging performance depends on the electrical installation, battery bank and connected loads.
Yes. Yanmar publishes the 2YM15 with an SD25 saildrive configuration as well as the KM2P-1 marine gear configuration. The correct option depends on the vessel’s propulsion layout and installation requirements.
The Yanmar 2YM15 14HP inboard diesel engine is a compact marine propulsion option for smaller sailboats and pleasure craft. Review the power rating, dimensions, weight, cooling system, alternator, control type and drive configuration above, then confirm compatibility with the vessel and installation before ordering.
