Operation323. Reposition the rod in the desired hole.To raise the bow (“trim-out”), move the rodaway from the transom.To lower the bow (“trim-in”), move the rod to-ward the transom.Make test runs with the trim set to differentangles to find the position that works best foryour boat and operating conditions.WARNINGEWM00400 Stop the engine before adjusting thetrim angle. Use care to avoid being pinched whenremoving or installing the rod. Use caution when trying a trim positionfor the first time. Increase speed gradu-ally and watch for any signs of instabil-ity or control problems. Improper trimangle can cause loss of control.TIP:The outboard motor trim angle can bechanged approximately 4 degrees by shiftingthe trim rod one hole.EMU27912Adjusting boat trimWhen the boat is on plane, a bow-up attituderesults in less drag, greater stability and effi-ciency. This is generally when the keel line ofthe boat is up about 3 to 5 degrees. With thebow up, the boat may have a greater tenden-cy to steer to one side or the other. Compen-sate for this as you steer. When the bow ofthe boat is down, it is easier to acceleratefrom a standing start onto plane.Bow UpToo much trim-out puts the bow of the boattoo high in the water. Performance and econ-omy are decreased because the hull of theboat is pushing the water and there is moreair drag. Excessive trim-out can also causethe propeller to ventilate, which reduces per-formance further, and the boat may “por-poise” (hop in the water), which could throwthe operator and passengers overboard.Bow DownToo much trim-in causes the boat to “plow”through the water, decreasing fuel economyand making it hard to increase speed. Oper-ating with excessive trim-in at higher speedsalso makes the boat unstable. Resistance at1. Trim rodZMU028591
