WARNING Improper trim angle Set the thrust rod (or preset knob) lower if the bow of the boat rises above horizontal. Excessive trim up or down may lead to unstable boat operation, potentially causing the steering difficulty that leads to accident during cruising. Do not cruise at high speed if improper trim position is suspected. Stop the boat and readjust trim angle before continuing cruise. For outboard motor model with PTT switch on the bottom cowl, do not operate the switch during cruising, or control of boat may be lost. Improper trim angle Set the thrust rod (or preset knob) higher if the bow of the boat is below horizontal. Set the thrast rod lower Remark) Thrust rod is for MF and EF, and preset knob is for EP. 13 Set the thrast rod higher 36 ENGINE OPERATION EFT and EPT type 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Improper Trim Angle (bow rise too high) If the trim angle is excessive, the bow will rise out of the water and the speed will decrease. Furthermore, the bow may sway or the bottom may slam the water while cruising. In this case, decrease the trim angle by pressing the switch on the Remote Control Lever to "DN". Down (DN) EFT model EPT model Proper Trim Angle The trim angle is optimum when the boat is parallel to the water surface while running. I mproper Trim Angle (bow dips into the water) If the trim angle is too small, the bow will dip into the water, the speed will decrease, and water may enter the boat. In this case, the trim angle should be increased by pressing the switch on the Remote Control Lever to UP "UP". ENGINE OPERATION 37 MF, EF type Stop the engine.

Do not cruise at high speed if improper trim position is suspected. Stop the boat and readjust trim angle before continuing cruise. For outboard motor model with PTT switch on the bottom cowl, do not operate the switch during cruising, or control of boat may be lost. Note Stop the engine before adjusting trim angle. ENGINE OPERATION 39 EFT/EPT type The provided Power tilt makes tiltup/down electrically. It may be used as a power trim and tilt when the outboard motor is used with the light load condition. In this case, it can be adjusted to set the desired trim angle of the outboard motor in relation to the transam shape, planing speeds and load. It is imperative that the trim angle is adjusted correctly. [. . . ] Remove the engine oil drain screw and completely drain water and oil from the engine. Remove the spark plugs, and completely drain the water from the engine by pulling the recoil starter several times. Replace oil filter and oil to the correct level. The oil and filter may need to be changed again after running a short period to get all moisture completely out of the crankcase. [. . . ]
