[55] [56]
To slip battery cable terminal cover (43) over the positive (Red) battery cable; Cut a hole or slot next to the sleeve on the terminal cover and split the sleeve with a knife. Use the tie strap (14) supplied to fasten the battery cable terminal cover to the positive battery cable next to the white sleeve. Pull the tie strap tight and trim off excess length.


Always place terminal cover over end of positive battery cable whenever cable is removed from battery. Do not run motor with cable disconnected and unshielded against grounding. Electrical sparks and possible fire and explosion can occur.

Install spark plug leads on spark plugs.

Step 6. Post Installation Tests

Connect battery leads to battery.

Do not connect any electrical equipment directly to the motor's charging system. If the motor is run without a battery the equipment could be damaged.

Install engine in test tank or use flushing adaptor.

Shift motor to NEUTRAL. Check operation of starter. Shift motor to FORWARD and REVERSE and pull starter. Starter lockout must prevent manual starter from cranking engine when shift handle is in FORWARD or REVERSE position.

Check the operation of the electric start system. Put shift lever in FORWARD, NEUTRAL, and REVERSE gear positions and depress start button in each position. Start button must not work in FORWARD or REVERSE.

Use stop button to stop engine.

The alternator output can be checked with an ammeter attached between the two red leads, one from the starter solenoid and the other from the rectifier. The output should be approximately 2 amps at 3000 rpm.

If a tachometer is required, be sure to use only one of the recommended five pulse type tachometers. Use of an incorrect tachometer will result in improper propeller selection and engine overspeeding. Engine overspeeding will result in serious damage to the powerhead.

To the Installer

** Give these installation instructions to the owner.** The instructions contain safety warnings and other information vital to the continued safe use of the product.

To the Owner

Retain these installation instructions with your Owner's/Operator's Manual. They contain installation, adjustment and operating information for future reference and part numbers for future service.

Always place terminal cover over end of positive battery cable whenever cable is removed from battery. Do not run motor with cable disconnected and unshielded against grounding. Electrical sparks and possible fire and explosion can result from grounding the battery cable on a running motor.
