Mechanical Marine Diesel for Repower Projects
The Yanmar 6LY2A-UTP 370HP uses direct injection through an in-line fuel injection pump and mechanical engine controls. Its six-cylinder layout, heat-exchanger cooling and 12V electrical equipment provide a clearly defined starting point for planning an installation.
For a motor cruiser or recreational sportfishing boat, assess the engine against the vessel’s displacement, propulsion demand and intended operating profile. An existing mechanical control installation may offer components for reuse, subject to compatibility checks.
Key features include:
- 5.813-litre displacement: Six cylinders arranged in line.
- Mechanical injection and controls: Manufacturer-specified in-line injection pump.
- Turbocharged and intercooled induction: Supports the engine’s published high-output rating.
- 12V electrical system: Published specifications include an 80A alternator.
- 535 kg dry weight: Engine only, excluding the marine gearbox. YANMAR Marine International

Understand the Power Ratings
MHP means metric horsepower. Yanmar’s specification sheet gives the 370 MHP rating under ISO 3046 conditions with fuel entering the injection pump at 25°C. It also publishes 359 MHP under ISO 8665 conditions at a 40°C fuel-inlet temperature. Check the reference conditions when comparing engine listings. yanmar.com
The operation manual separately lists 290 MHP at 3,100 rpm as continuous power and identifies the engine for recreational use. Maximum output, continuous output and propeller-shaft power are distinct figures. The continuous rating does not establish approval for unrestricted commercial service. yanmar.com
If your installation requires a different output, compare the Yanmar 6LY2A-STP marine inboard diesel engine within the same engine family.
Marine Gearbox Options
Yanmar’s published transmission configurations include:
- KMH60A: An 8-degree down-angle marine gearbox with a hydraulic multi-disc clutch.
- ZF280-1 and ZF280-1A: Additional gearbox arrangements listed in the manufacturer’s documentation. yanmar.com
The gearbox model, reduction ratio and shaft geometry must suit the vessel’s propeller demand and installation. Confirm these details before retaining an existing transmission or selecting a replacement.
Review the official Yanmar 6LY2A-UTP/STP specification sheet for reference. Final installation planning requires drawings for the selected engine, gearbox and exhaust configuration.
Compare Complete Engine Packages
A useful Yanmar 6LY2A-UTP 370HP price should make the supply scope clear. Request written confirmation of:
- Engine condition, serial number and operating hours where applicable.
- Available service history, rebuild records and inspection or running-test evidence.
- Gearbox model and ratio, instruments, wiring, mounts and exhaust components included.
- Warranty provider, coverage, exclusions and commissioning requirements.
- Availability, packing, dispatch estimate and delivery charges.
For a repower enquiry, photographs of the existing engine and gearbox identification plates help establish the installation details. Your installer should also check engine beds, cooling-water supply, exhaust routing and maintenance access.
Frequently Asked Questions
Does the Yanmar 6LY2A-UTP 370HP have mechanical controls?
Yes. Yanmar specifies mechanical engine management and direct injection through an in-line pump. YANMAR Marine International
Why do some specifications show 359 MHP instead of 370 MHP?
Yanmar publishes both figures under different rating conditions. Its 2021 specification sheet lists 359 MHP under ISO 8665 and 370 MHP under ISO 3046. yanmar.com
Does the engine include a gearbox and warranty?
These depend on the offered package and engine condition. Request an itemised quotation and the applicable warranty terms before ordering.
