Understanding the M.L Rating Description
Yanmar publishes the Yanmar 4JHYE 35HP across M and L duty ratings. The 35 MHP specification corresponds to the M-rating at 3,400 rpm. yanmar.com
Select the rating around the vessel’s expected annual hours, daily operating pattern and engine loading. M and L have defined operating limits, so the quotation should identify the approved rating for the particular engine. Do not assume unrestricted continuous full-load operation from the model’s commercial classification. yanmar.com

Hydraulic Gearbox and Propulsion Matching
Yanmar identifies the YX-10 hydraulic marine gearbox in its published 4JHYE reference specifications. Request confirmation of the gearbox supplied, reduction ratio, output coupling and associated controls. yanmar.com
The correct ratio depends on the vessel’s propeller, shaft arrangement, displacement and intended cruising speed. Retaining an existing transmission requires an assessment of its input rating, connection and installation geometry.
Review the official Yanmar commercial JH Series specifications for manufacturer reference information.
Plan Your Engine Replacement
For a Yanmar 4JHYE 35HP repower, assess the engine beds, shaft alignment, propeller demand, exhaust routing, seawater supply and service access before finalising the package.
Provide photographs of the existing engine and gearbox identification plates with your enquiry. Include available engine-room measurements and propeller details so your installer can assess the proposed configuration.
The published package dimensions provide a useful starting point. Installation planning must also allow for connections, ventilation and maintenance clearance.
