Control lever - Speed shift and turn control. Applicable to all boats with hinged or built-in motors or Z-drive. The installation is a simple adjustment on both sides of the boat - both horizontally and vertically. The B184 control box is equipped with a triple control button. In the event of a misalignment from ''forward'' to ''reverse'', a neutral position (idle) between the two gears prevents damage to the gear unit. By pushing the button on the bottom of the handle, the engine speed can be raised without the gear engaged - for example, to warm up the engine with the required number of revolutions.
