  • Page 20: Controls

    The shift function and engine speed control are combined in one lever. The shift function can be simply disengaged so that only engine speed is affected. The Volvo Penta controls are available for top or side mounting. The control levers have an adjustable friction brake. A neutral position switch is available as an accessory, this will only permit the engine to be started with the drive disengaged.
  • Page 21 Adjustment of friction brake The friction brake only affects engine speed adjust- ment. Adjust with the lever in the throttle half open position (forward/reverse). Remove the cover over the control. For side- mounted controls the lever must first be removed. Adjust the friction brake by turning the screw at the arrow (see figure).
  • Page 22: Power Trim

    Power Trim Your Volvo Penta drive has a Power Trim system as standard equipment. The purpose of Power Trim is to al- low the helmsman to change the angle at which the drive is set, without leaving the cockpit. Changing this angle relative to the bottom of the boat is referred to as trimming.
  • Page 23 Control lever Control button (2) in the control lever is used to raise the bow, by pressing the top half, and to lower the bow by pressing the lower half of the button. To put the drive in the “Beach” position, you have to press a se- parate switch to bypass the catch which prevents entry to the “Beach”...
  • Page 24: Trim Instruments

    Trim instruments The SX drive only has an analogue trim instrument. The DP-S drive can either have an analogue or digital trim in- strument. Analogue trim instrument (SX, DP-S) The trim instrument indicates the current trim position. It has a scale with five segments and three main ranges: 1.
  • Page 25 TRIM = Drive position at all speeds. Max trim up to 5. BEACH = Used for operation at in shallow water where water depth is uncertain. Speed should always be low, max. 1000 rpm. 5 - 40. LIFT = Flashing red warning lamp. Drive up completely 41 - 51. See LEDs position 1.
  • Page 26: Impact Protection

    If there is obvious or suspected damage, operate boat at low RPM and take your boat to a Volvo Penta dealer for inspection. Have necessary repairs made immediately. Operating a damaged drive unit could cause additional damage and could become very costly to repair.
  • Page 27: Starting The Engine

    Starting the Engine Familiarize yourself with the operation of the remote control supplied with your boat, then proceed as follows. IMPORTANT! Pumping bilge: Frequently check bilge for leaking engine, power steering, or trim system oil. Find the cause and correct it immediately. Regulations prohibit the pumping of oil into any navigable waters.
  • Page 28: Starting

    Starting NOTE! Do not start engine out of water unless using a flushing adapter. WARNING! When using a flushing adaptor, remove the propellers befor starting engine to prevent accidental con- tact with moving propellers. If propellers are not removed, personal injury could result. Move the control lever to the neutral/idle position.
  • Page 29: If Engine Floods

    If engine floods Gi, GSi models: A flooded engine can be cleared by advancing the control handle to a position of 3/4 throttle. In this throttle position and the engine speed below 400 RPM (cranking speed) the ECM turns off the fuel injectors so no fuel is delivered. When the th- rottle position is moved to full throttle or less than 3/4 throttle, the ECM returns to the starting mode.
  • Page 30: Operation

    Operation All shifting between forward/reverse must be done at engine idle speed. Shifting at higher speeds may damage the drive/reverse gear and will also be uncomfortable for those on board. If the boat has two or three engines, it is important that they are all running during maneuvers astern (rearward movement), otherwise water might get into the exhaust of the engine which is not running when the backwash catches up with the boat.
  • Page 31: Engine Protection Mode

    NOTE: Should the problem continue, contact your nearest Volvo Penta dealer and have the engine checked. Master/slave installation Gi, GSi For twin unit installations both engine EMCs can be tied to- gether electronically.
