  • Page 21: General Information

    GENERAL INFORMATION Boater's Responsibilities The operator (driver) is responsible for the correct and safe operation of the boat and safety of its occupants and general public. It is strongly recommended that each operator (driver) read and understand this entire manual before operating the outboard. Be sure at least one additional person on board is instructed in the basics of starting and operating the outboard and boat handling in case the driver is unable to operate the boat.

  • Page 22: Boat Horsepower Capacity

    For additional information, obtain a copy of our Hi-Performance Boat Operation booklet (part number 90-849250--1) from your dealer, distributor, or Mercury Marine. ob00307...

  • Page 23: Outboard Remote Control Models

    GENERAL INFORMATION Outboard Remote Control Models The remote control connected to your outboard must be equipped with a start in neutral only protection device. This prevents the engine from starting when the shift is actuated in any position other than neutral. WARNING Avoid serious injury or death from a sudden unexpected acceleration when starting your engine.

  • Page 24: Lanyard Stop Switch

    GENERAL INFORMATION Lanyard Stop Switch The purpose of a lanyard stop switch is to turn off the engine when the operator moves far enough away from the operator's position (as in accidental ejection from the operator's position) to activate the switch. Tiller handle outboards and some remote control units are equipped with a lanyard stop switch.
  • Page 25 GENERAL INFORMATION While activation of the lanyard stop switch will stop the engine immediately, a boat will continue to coast for some distance depending upon the velocity and degree of any turn at shut down. However, the boat will not complete a full circle.

  • Page 26: Protecting People In The Water

    GENERAL INFORMATION Protecting People In The Water WHILE YOU ARE CRUISING It is very difficult for a person standing or floating in the water to take quick action to avoid a boat heading in his/her direction, even at slow speed. ob00311 Always slow down and exercise extreme caution any time you are boating in an area where there might be people in the water.

  • Page 27: Fishing Seats

    GENERAL INFORMATION Persons on the front deck could easily be thrown overboard or persons dangling their feet over the front edge could get their legs caught by a wave and pulled into the water. ob00312 WARNING Avoid serious injury or death from falling over the front end of a pontoon or deck boat and being run over by the outboard.

  • Page 28: Wave And Wake Jumping

    GENERAL INFORMATION Wave And Wake Jumping Operating recreational boats over waves and wake is a natural part of boating. However, when this activity is done with sufficient speed to force the boat hull partially or completely out of the water, certain hazards arise, particularly when the boat re-enters the water.

  • Page 29: Impact With Underwater Hazards

    GENERAL INFORMATION Impact With Underwater Hazards Reduce speed and proceed with caution whenever you drive a boat in shallow water areas, or in areas where you suspect underwater obstacles may exist which could be struck by the outboard or the boat bottom. The most important thing you can do to help reduce injury or impact damage from striking a floating or underwater object is to control the boat speed.

  • Page 30: Safety Instructions For Hand Tilled Outboards

    GENERAL INFORMATION The boat should also be checked for any hull fractures, transom fractures, or water leaks. Operating a damaged outboard could cause additional damage to other parts of the outboard, or could affect control of the boat. If continued running is necessary, do so at greatly reduced speeds.
  • Page 31 GENERAL INFORMATION Early symptoms of carbon monoxide poisoning which should not be confused with seasickness or intoxication, include headache, dizziness, drowsiness, and nausea. WARNING Avoid the combination of a running engine and poor ventilation. Prolonged exposure to carbon monoxide in sufficient concentration can lead to unconsciousness, brain damage, or death.

  • Page 32: Selecting Accessories For Your Outboard

    Some accessories not manufactured or sold by Mercury Marine are not designed to be safely used with your outboard or outboard operating system. Acquire and read the installation, operation, and maintenance manuals for all your selected accessories.
  • Page 33 GENERAL INFORMATION Know and obey all nautical rules and laws of the waterways. Boat operators should complete a boating safety course. Courses are offered in the U. S.A. by 1) The U.S. Coast Guard Auxiliary, 2) The Power Squadron, 3) The Red Cross and 4) your state boating law enforcement agency.

  • Page 34: Recording Serial Number

    GENERAL INFORMATION Report accidents. Boat operators are required by law to file a Boating Accident Report with their state boating law enforcement agency when their boat is involved in certain boating accidents. A boating accident must be reported if 1) there is loss of life or probable loss of life, 2) there is personal injury requiring medical treatment beyond first aid, 3) there is damage to boats or other property where the damage value exceeds $500.00 or 4) there is complete loss of the boat.

    INSTALLATION Installing Outboard NOTE: If outboard is a remote control electric start model, follow instructions in the outboard installation manual (provided with the outboard) for installing remote steering shift and throttle cables and remote wiring harness. BOAT TRANSOM HEIGHT REQUIREMENT 1.

  • Page 37: Battery Installation - Electric Start Models

    INSTALLATION 3. Fasten outboard by drilling two 7.9 mm (5/16 in.) holes through the transom using transom clamp holes as a template. Fasten with two bolts, flat washers and locknuts. The use of clamp handles alone is insufficient to properly and safely secure the outboard to the transom. Use a marine waterproofing sealer in holes and around bolts to make the installation water tight.

  • Page 38: Propeller Selection

    INSTALLATION DISCONNECTING OUTBOARD BATTERY CABLES 1. First, disconnect the black battery cable from the (-) negative terminal and then disconnect the red battery cable from the (+) positive terminal. ob00506 Propeller Selection The propeller supplied with your outboard provides the best overall performance under average operating conditions.

  • Page 39: Carrying Outboard

    TRANSPORTING Carrying Outboard The outboard has a carrying handle located in front and a rear hand grip in the bottom cowl. 3020 Trailering Boat IMPORTANT: The tilt lock mechanism is not intended to support the outboard in the tilted up position when trailering. Use of the tilt lock mechanism could allow the outboard to bounce and drop down causing damage to the outboard.

  • Page 40: Transporting Outboard When Removed From Boat

    TRANSPORTING Set the gear shift into forward gear. This prevents the propeller from spinning freely. Transporting Outboard When Removed From Boat 1. With the outboard still in the water, disconnect the fuel line from the outboard and run engine until it stops. This will drain fuel from the carburetor.
  • Page 41 TRANSPORTING 2. Install tether cap over the fuel line connector stem. This will protect the connector stem from being accidently pushed-in, thus, allowing fuel or vapor to escape. ob00326 Connector stem Tether cap...

  • Page 42: Fuel & Oil

    Ether (MTBE or ETBE). If Ethanol is the oxygenates that is used in the gasoline, refer to Alcohol in Gasoline. These reformulated fuels are acceptable for use in the Mercury engine. ALCOHOL IN GASOLINE We do not recommend the use of gasoline which contains alcohol because of the possible adverse effect the alcohol may have on the fuel system.

  • Page 43: Oil Recommendation

    Outboard Oil IMPORTANT: Oil must be NMMA certified TC-W3 2-Cycle oil. Mercury or Quicksilver Premium TC-W3 2-Cycle oil is recommended for this engine. For added protection and lubrication, Mercury or Quicksilver Premium Plus TC-W3 2-Cycle oil is recommended. If Mercury or Quicksilver outboard oil is not available, substitute another brand of 2-cycle outboard oil that is NMMA Certified TC-W3.

  • Page 44: Filling Fuel Tank

    FUEL & OIL Filling Fuel Tank WARNING Avoid serious injury or death from a gasoline fire or explosion. Always stop the engine and do not smoke or allow open flames or sparks in the area while filling fuel tanks. Fill fuel tanks outdoors away from heat, sparks, and open flames. Always stop engine before refilling tanks.
