Part of the Yanmar Operator Manuals.
All 46 pages of this Yanmar Marine Gear Operation Manual (OEM #0AKMH-G00201) are built around one job: keeping your KMH60A, KMH61A, or KMH61V transmission shifting clean and running right. Inside: complete marine gear oil specifications, a daily visual check routine, and step-by-step shifting procedures for normal operation, towing, and anchoring. You also get a full torque chart covering every fastener from M6 through M14, a periodic maintenance schedule with 50-hour and 250-hour service intervals, a troubleshooting chart, and detailed coverage of optional accessories including electric and mechanical trolling valves. Fill the KMH60A or KMH61A to 2.8 L (3.0 qt) without a heat exchanger, and torque transmission M10 assembly bolts to 37.2–41.2 N·m (27.5–30.4 lb-ft). Your gear is in, the engine's running, and you need the right spec now. Bookmarked and searchable; pull it up dockside on any device.
