Disconnect the battery cord of the EF, EP, EFT or EPT type engine, if the engine will not be used for more than 3 days. 34 ENGINE OPERATION 5. Trim angle ! 1 2 3 4 5 6 7 8 9 10 11 12 13 14 The trim angle of the outboard motor can be adjusted to suit the transom angle of the hull, and load conditions. Choose an appropriate trim angle that will allow the anti-ventilation plate to run parallel to the water surface during operation. Proper trim angle The position of the thrust rod (or preset knob) is correct if the hull is horizontal during operation. Perpendicular to the water surface Do not put hand or finger in between outboard motor body and clamp bracket when adjusting trim angle to prevent injury in case the outboard motor body falls. When testing a trim position, run boat slow initially to see if it can be controlled safely. ! 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. 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. Knob Remark) Thrust rod is for MF and EF, and preset knob is for EP. Knob ENGINE OPERATION 35 EFT and EPT type 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) 1 EFT model 2 3 EPT model 4 5 Proper Trim Angle The trim angle is optimum when the boat is parallel to the water surface while running. 6 7 8 9 10 11 12 13 Improper 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". 36 ENGINE OPERATION MF, EF type 1 2 3 4 5 6 7 8 9 10 11 12 Stop the engine. Gentry lower the outboard. Thrust Rod Higher Lower a b Transom angle settings Tilt release position EP type Stop the engine. Gently lower the outboard. ! Do not put hand or finger in between outboard motor body and clamp bracket when adjusting trim angle to prevent injury in case the outboard motor body falls. When testing a trim position, run boat slow initially to see if it can be controlled safely. Preset Knob 13 14 ENGINE OPERATION 37 EPT type Operate the Power Tilt switch and tilt the outboard motor up. (The Main Switch must be "ON". ) Lock the tilt with the Tilt stopper after the outboard motor has been tilted up. 1 Tilt Stopper The outboard motor can also be tilted up using the switch provided under the bottom cowl. (The Main Switch need not be turned "ON" in this case. ) Manual tilting If the battery is dead, and the Power Tilt Switch inoperative, turn the manual valve to counterclockwise. This will allow manual tilting of the outboard motor. 2 3 4 5 POWER 6 7 8 9 10 11 12 13 MANUAL EFT type Operate the Power Tilt switch and tilt the outboard motor up. ! Excessive trim up or down may lead to unstable boat operation, potentially causing the steering difficulty that leads to accident during cruising. 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. 38 ENGINE OPERATION EFT/EPT type 1 2 3 4 5 6 7 8 9 10 11 12 13 14 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. Incorrect adjustment will cause the boat to sway, deteriorate engine performance and may cause unsafe steering conditions. ! The power Tilt can be set to any trim angle, however, avoid cruising with the outboard motor tilted in the tilt range. Operating the boat in this manner, the outboard motor may ingest air into the water cooling system, resulting in engine overheadting. 4° 75° ENGINE OPERATION 39 6. Tilt up, tilt down and shallow water operation ! Tilt down Slightly tilt the motor up, and pull the tilt lever toward you to release the tiltlock. [. . . ] Motor submerged in water After taking your outboard motor out of the water, immediately take it to your dealer. The following are the emergency measures to be taken for a submerged outboard motor, if you can not take it your dealer right away. 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. [. . . ]
