Trolling valve Transmission system
For installation on the hydraulically operated reverse gear units. Permits a lower speed than is otherwise possible, for example when sport fishing. The trolling valve reduces the propeller speed at a given engine speed. In trolling mode the oil pressure in the discs is reduced enough to permit controlled slip in the disc assembly of the reverse gear unit. The trolling valve is able to reduce propeller speed by up to 80%. It cannot be used with electrically operated reverse gear units.
Note! The engine speed must not exceed 1200 rpm in trolling mode, to avoid overheating of the discs.
