Marine Gearbox
The gearbox on a marine diesel engine has three purposes: to reduce the maximum speed at which the propeller rotates; to enable both forward and astern rotation of the propeller; and to enable the propeller to remain stationary when the engine is running. Unlike a car gearbox, there is usually only one forward gear and the clutch is contained within the gearbox.
Because modern engines run at too high a speed for normal operation of the propeller, gearing reduction is required. The reduction gear ratio is usually between 2:1 and 3:1, with different manufacturers often using differing ratios.

The Kanzaki KM35A-2 is a compact, mechanical angle servo cone clutch marine transmission designed for Yanmar diesel engines. It features a lightweight design (approx. 13 kg) with a 7-degree down-angle output, commonly used in sailboats and small pleasure craft with reduction ratios of 2.33 or 2.64, and requires SAE #20/#30 oil.
Smooth and reliable hydraulic shifting with control lever for attachment of push-pull cable.Robust design also withstands continuous duty in workboat applications. Fully works tested, reliable and simple to install. Design, manufacture and quality control standards comply with ISO 9001. Compatible with all types of engines and propulsion systems, including waterjets and surface- piercing propellers, as applicable.
