TROLL AND THROTTLE RESPONSE
Troll mode allows the vessel to operate at very low speeds by controlling the
transmission. The transmission is capable of reducing the propeller speed lower than the
engine speed. Lever control is adjusted so that trolling occurs within the first 25% of lever
travel. From 26% to 100% lever travel the engine operates between idle speed and
maximum rated engine speed.
