2-34Throttle ControlThe throttle lever is located to the right of the driver.When the throttle is vertical, it is in the “NEUTRAL”position. At the base of the throttle you will find the shiftlock knob. Pulling outward on this knob disengages thetransmission, thereby allowing use of the throttle withoutengaging the transmission. This is needed for starting andwarm-up of the engine. Be sure to position the throttlevertically (in “NEUTRAL”), before re-engaging thetransmission, by depressing the knob.When engaging the transmission from “NEUTRAL” toeither forward or reverse, you must pull up on the safetycollar located directly below the throttle lever knob. The2009 ZF throttle has the safety button located at the topof the throttle knob.Notice: All 2009 ZF throttle controls do notoffer the “Neutral Only” function.Do not shift from forward to reverseat high RPMs; damage to thetransmission will result. When shiftingfrom forward to reverse you must stopin the NEUTRAL position, doing this allows the engine to runin its idle position before moving into the opposite gear.Moving the shift lever from FORWARD to REVERSE withoutstopping in NEUTRAL can cause the transmission to “slam”into gear, damaging the transmission and/or causing theengine to shut off. This will cause temporary loss of boatcontrol which can cause damage and/or injury to the boatand/or persons in/or around the boat.Before starting the engine or engaging transmission, ensureall swimmers are out of the water.Electronic Throttle Control (ETC)All 2006-2009 Malibu Boats are equipped with electronic throttle control AKA “Fly-By-Wire.” The throttle cable has been removed and several components on the engine and helmthrottle control have been changed. The helm throttle control “E-MV3” is now dual, variablevoltage potentiometer that sends electronic signals back to the engine ECM via a shieldedwire harness with the highest quality GM/Delphi water-tight connectors that mates to theengine ECM. The ECM then uses the signals from the E-MV3 to precisely control the enginespeed with an electronic throttle body.Figure 2-17. Throttles
