  • TROLLING VALVESThere are three types of trolling valvesavailable: mechanical and two types ofelectric trolling.The trolling mode option allows the boatoperator to slow the forward and aft speedof the boat for fishing.Electronic trolling mode is achieved by theECU electronically adjusting the pressurebypass valves in the gearbox, allowing theclutches to slip. The trolling option (ifequipped) is activated by putting the controllever in NEUTRAL and pressing the trollingswitch or button located near the shift /throttle control head. Refer to the electroniccontrol system manual for more information.NOTICE: The throttle lever does notoverride the trolling valve. The trollingfunction must be OFF before resumingnormal travel speed.Mechanical Trolling ValveThis trolling valve does not give feedback offluctuations in the propeller speed.Shifting Pressure Adjustment

    Figure 7When the rubber cap (Figure 6, (1)) isremoved, the lock nut (Figure 6, (2)) isloosened, and the adjustment screw(Figure 6, (3)) is rotated clockwise(tightened), the angle of a lever(Figure 7, (1)) lowers the shifting pressureand reduces the speed of the boat. NOTICE:Use the trolling valve once daily. Theorifice (Figure 6, (4)) can clog when thetrolling valve is not used for extendedperiods of time, resulting in unexpectedengagement of the valve.Note: When the trolling valve is not beingused, secure it in place so that it does notmove from vibration of the boat.
