Auto Trim System Description NOTE: The only difference between AUTO TRIM and AUTO TRIM Il, is that AUTO TRIM II has an Adjustment Knob on the Control Module. The Auto Trim System consists of the following major components: Auto Trim Pump same pump that is used on the standard Power Trim models. Control Module a solid-state electronic device that senses engine RPM and regulates the time at which the drive unit trims In and Out when operating in the AUTO mode. Module is protected by a 20-amp fuse. Mode Switch allows the operator to select either AUTO or MANUAL trim operation from the dash. Manual Trim Control will only function with mode switch in the MANUAL mode and ignition switch in the RUN position. Allows the operator to raise and lower the drive unit for trailering, beaching, launching and shallow water operation. Also, allows the operator to manually adjust the drive unit trim angle while underway in situations where automatic trimming is not desired (rough seas, etc.). Trim Limit Switch Establishes the maximum trim Out limit in both the MANUAL and AUTO mode. Prevents drive unit from moving out of the gimbal ring support flanges, which could cause possible damage to stern drive if it were to occur at higher engine speeds.

Auto Trim Operation The Auto Trim system is designed to allow either automatic or manual trimming of the boat while underway in addition to allowing drive unit to be raised for trailering, beaching, launching or shallow water operation. A 2-position switch on dashboard allows the operator to select the mode desired. Boat Running Above Planing Speed Auto Trim Mode Switch AUTO MODE OPERATION 22217! WARNING Drive unit will automatically lower from the raised position when the ignition switch is turned to the RUN position and mode switch is placed in the AUTO mode. BE SURE THAT NO ONE IS IN THE AREA OF THE DRIVE UNIT. With mode switch in the AUTO mode, the drive unit will move automatically to properly trim boat while underway. This allows boat operator to keep both hands on the steering wheel and to direct operator s full attention to drive the boat. At engine speeds below 3100 RPM, the drive unit will remain in the full In position. This will force the bow of the boat down and help it get up on plane quickly. Once engine reaches 3100 RPM and after a 5-6 second delay (to ensure that boat is up on plane), the drive unit will automatically trim Out to a preset position for maximum boat speed and efficiency. Trim Out position can be adjusted to fine tune the trim angle for each individual boat. Upon deceleration, the drive unit will trim In when engine reaches 2600 RPM. Most boats will still be up on plane at this point. After drive reaches full In position, the trim pump motor will continue to run for approximately 5 seconds. NOTE: The AUTO mode also can be used to lower the drive unit from the fully raised (trailering) position. By placing ignition switch in RUN position and mode switch in AUTO mode, the drive unit will automatically lower to the full In position. Be sure that no one is in the area of the drive unit. Boat Running Below Planing Speed MANUAL MODE OPERATION Placing the mode switch in the MANUAL position will deactivate the AUTO system and allow the operator to adjust drive unit position, using the manual trim control. Typical controls are shown following. Manual trimming may be desirable to fine tune the trim angle for a particular water condition or boat load, or in situations where greater control over the trim operation is needed. Manual trim control also must be used to raise the drive unit for trailering, beaching, launching and shallow water operation. Ignition switch must be in the RUN position for manual trim control to function. 1.

2. TRIMMING DRIVE UNIT OUT (BOW UP ). Press switch until drive unit moves to properly trim boat or trim limit switch stops outward travel. 22212 Quicksilver Commander Panel Trim Control a - Trailer Switch Press Until Drive Unit Reaches Desired Height or End of Upward Travel NOTE: Some Power Trim pump motors are protected from overheating by an internal circuit breaker. If trailering switch(es) are held depressed after drive unit reaches end of upward travel, internal circuit breaker will open and pump will stop. If this should happen, release switch(es) and allow motor to cool for approximately 2 minutes. Once motor is cool, circuit breaker will reset automatically, and trim operation may be resumed.! CAUTION DO NOT run engine above idle RPM with unit raised for shallow water operation, as drive unit is out beyond gimbal ring support flanges and has no side support. USE EXTREME CAUTION WHEN OPERATING BOAT WITH DRIVE UNIT RAISED.

! CAUTION NEVER trim the drive unit Out using the Trailer switch(es) while boat is underway. Severe damage to drive unit may result if the unit is raised beyond the gimbal ring support flanges at engine speeds above idle RPM. 3. TRIMMING DRIVE UNIT IN (BOW DOWN ) Press switch until drive unit moves to properly trim boat or until drive unit reaches end of downward travel. Electrical System Overload Protection The Auto Trim electrical system is protected from overload by a 110-amp fuse, and a 20-amp in-line fuse at control module positive (+) battery lead and a 20-amp in-line fuse at ignition switch (if Quicksilver ignition switch is used). If boat is equipped with 3-Button Control Panel, a 20-amp in-line fuse also is located at panel. If Auto Trim electrical system becomes inoperative, check for a blown fuse. If fuse has blown, the cause for overload MUST BE found and corrected BEFORE replacing fuse. Auto Trim Limit Adjustment In most cases, best all-around performance is obtained with drive unit adjusted so that front of hull will be slightly out of water when boat is on plane. Quicksilver 3-Button Trim Control Panel a - In Button Press 22174 Boat Properly Trimmed Adjusting the drive unit Out from this position will tend to raise the bow of the boat, thus further reducing the wetted surface of the hull and, in some cases, increasing boat speed. However, if trimmed out excessively, bouncing, porpoising, propeller ventilation and possible difficult steering control could result. Bow Too High Move Drive Unit In 22212 Quicksilver Commander Panel Trim Control a - Trim Switch Press Down on Switch 5F-4 - AUTO TRIM AND AUTO TRIM II 90-12934--2 1097
Adjusting the drive unit In from normal position will force the bow of the boat down, thus increasing the wetted surface of the hull and, in some cases, improving boat ride in rough water (at partial throttle). However, this will reduce boat speed in most cases. 3. Place Auto Trim mode switch in the MANUAL mode; turn ignition key to the RUN position.
