KMH52V

Higher-torque (684 Nm) version of Kanzaki's 12-degree hydraulic V-drive, the V-drive gear on Yanmar's 8LV V8.

The KMH52V shares the KMH50V's 12-degree V-drive layout, ratios (1.22, 1.58, 2.08 and 2.47:1), 5.4 L oil capacity and 59 kg dry weight with Borg-Warner bell housing, but is rated at 684 Nm input. Mechanical and C-type trolling options are listed.

Yanmar's 8LV datasheet names it as the V-drive option beside the KMH50A down-angle gear, and Yanmar publishes an 8LV x KMH52V drawing.
