Mercury MerCruiser Bravo Outdrives Sterndrives Marine Engines Service Manual Number 28

AUTO TRIM II
SERVICE MANUAL NUMBER 28
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 sterndrive unit adjusted so that
front of hull will be slightly  out of water when boat is on plane.
Boat Properly Trimmed
Adjusting the sterndrive unit OUT from this position will tend to raise the  bow of the boat,
reducing  the wetted  surface of  the hull  and, in  some cases,  increasing boat  speed. If
trimmed out excessively, bouncing,  porpoising, propeller ventilation and possible difficult
steering control could result.
Bow Too High - Move Sterndrive Unit IN
Adjusting the sterndrive unit IN from  normal position will force the bow of the boat down,
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.
Bow Too Low - Move Sterndrive Unit OUT
