Operation343. 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
