0285751 EVINRUDE ENGINE COVER Ay, Blue - 150 H.O.

Do not engage starter when flywheel is turning.Do not start engine under load.
1. Apply the brake. Place the transmission in NEUTRAL.2. Turn the disconnect switch (if equipped) ON.3. Depress accelerator. For air start systems, before starting the engine, check the air supply. There must be 690 kPa (100 psi) air pressure available.4. Turn start switch to START position or push the air start button in. Release the switch as soon as the engine starts.5. Allow the engine to idle for three to five minutes, or until the water temperature gauge has begun to rise.6. Do not apply load to the engine or increase engine speed until the oil pressure gauge indicates normal.
If oil pressure does not raise within 15 seconds after the engine starts, stop the engine and make necessary corrections.
7. Operate the engine at low load until all systems reach operating temperatures. Check all gauges during the warmup period.Below 0°C (32°F)
Ether is poisonous and flammable.Do not store replacement cylinders in living areas.Do not smoke while changing cylinders.Use only in well ventilated areas.Use with care to avoid fires.Avoid breathing of vapors or repeated contact with skin.Do not puncture or burn cylinders.Discard cylinders in a safe place.Keep ether container away from heat, sparks, open flame, or open sunlight. It may explode.Do not store replacement cylinders at temperatures above 49°C (120°F).Do not use cylinders in environments above 93°C (200°F).
1. Depress ether switch and hold for 3 seconds, then release. For air start system, before starting the engine, check the air supply. There must be 690 kPa (100 psi) air pressure available.2. Turn the start switch to START position or push the air start button in.3. Begin cranking engine and depress ether switch and hold for 3 seconds then release. Additional injections of ether may be required to start and/or achieve low idle speed.4. Run at low idle until engine will run smoothly at high idle.5. Allow white smoke to clear up and proceed with normal operation.
Do not use excessive starting fluid during starting or after the engine is running.After every 30 seconds of engine cranking, allow 2 minutes for the starter motor to cool.If oil pressure does not rise within 15 seconds after the engine starts, stop the engine and make necessary corrections.
6. Operate the engine at low load until all systems reach operating temperatures. Check all gauges during the warmup period. Turn the disconnect switch (if equipped) OFF after the engine is stopped to prevent battery discharge.For starting below -18°C (0°F), use of optional cold weather starting aids are recommended. A coolant heater or extra battery capacity may be required.Temperatures below -23°C (-10°F) consult your Caterpillar dealer, or refer to the Cold Weather Operation Guide, Form SEBU5898, available from your Caterpillar dealer.Starting From External Electrical Source
Always wear protective glasses when working with batteries.Prevent sparks near the batteries. They could cause vapors to explode. Do not allow cable ends to contact each other or the engine.Batteries give off flammable fumes that can explode.Do not smoke when observing the battery electrolyte levels.Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.Do not allow the free end of booster cables to make contact with each other or touch the vehicle. This will help avoid sparks.
Be sure the disconnect switch (if equipped) and the main power switch are in the OFF position and the keys removed before attaching the booster cables to the vehicle being started.When using booster cables, be sure to connect in parallel: POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-).Use only equal voltage for boost starting. The use of a welder or higher voltage will damage the electrical system.
Engines installed in vehicles without engine-to-frame ground straps can be damaged by electrical discharge.To prevent electrical discharge damage, check to make sure the vehicle's system has an engine-to-frame ground strap. For vehicles which have the alternator connected to an engine component, the ground strap must connect that component to the frame.Some vehicles have starter-to-frame ground straps. But, many of these starters are not electrically grounded to the engine. They have electrical insulation systems. For this reason, the starter-to-frame ground strap may not be an acceptable ground.Connect one end of cable to the POSITIVE (+) (ungrounded) terminal of the battery on the vehicle being started. Connect the other end to the POSITIVE (+) terminal of the power source.Connect one end of the second cable to the NEGATIVE (-) terminal of the power source. Connect the other end to the frame of the vehicle to be started.Insert the key and turn the disconnect switch on.Start the engine.Disconnect the cable from the vehicle frame first. Disconnect the other end from the NEGATIVE (-) terminal of the power source. Disconnect the cable from the POSITIVE (+) terminal of the battery. Disconnect the other end from the POSITIVE (+) terminal of the power source.
