  • Page 11: General Information

    GENERAL INFORMATION Boater's Responsibilities The operator (driver) is responsible for the correct and safe operation of the boat and the safety of its occupants and general public. It is strongly recommended that each operator read and understand this entire manual before operating the outboard.

  • Page 12: High-Speed And High-Performance Boat Operation

    For additional information, obtain a copy of our Hi‑Performance Boat Operation booklet from your dealer, distributor, or Mercury Marine. Outboard Remote Control Models The remote control connected to your outboard must be equipped with a start in neutral only protection device.

  • Page 13: Remote Steering Notice

    GENERAL INFORMATION Remote Steering Notice WARNING Improper fasteners or improper installation procedures can result in loosening or disengagement of the steering link rod. This can cause a sudden, unexpected loss of boat control, resulting in serious injury or death due to occupants being thrown within or out of the boat. Always use required components and follow instructions and torque procedures.
  • Page 14 GENERAL INFORMATION The lanyard cord is usually 122–152 cm (4–5 feet) in length when stretched out, with an element on one end made to be inserted into the switch and a clip on the other end for attaching to the operator's PFD or wrist. The lanyard is coiled to make its at‑rest condition as short as possible to minimize the likelihood of lanyard entanglement with nearby objects.
  • Page 15 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 16: 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. 21604 Always slow down and exercise extreme caution any time you are boating in an area where there might be people in the water.
  • Page 17 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. 26782 WARNING Sitting or standing in an area of the boat not designed for passengers at speeds above idle can cause serious injury or death.

  • Page 18: Wave And Wake Jumping

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 enters the water.

  • Page 19: 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 20: Safety Instructions For Hand-Tilled Outboards

    Operating a boat or engine with impact damage can result in product damage, serious injury, or death. If the vessel experiences any form of impact, have an authorized Mercury Marine dealer inspect and repair the vessel or power package. Safety Instructions for Hand‑Tilled Outboards No person or cargo should occupy the area directly in front of the outboard while the boat is in motion.
  • Page 21 GENERAL INFORMATION WARNING Inhaling engine exhaust gases can result in carbon monoxide poisoning, which can lead to unconsciousness, brain damage, or death. Avoid exposure to carbon monoxide. Stay clear from exhaust areas when engine is running. Keep the boat well‑ventilated while at rest or underway. STAY CLEAR OF EXHAUST AREAS 41127 Engine exhaust gases contain harmful carbon monoxide.

    INSTALLATION Mercury Marine Validated Engine Mounting Hardware IMPORTANT: Mercury Marine provides validated fasteners and installation instructions, including torque specifications, with all of our outboards so they can be properly secured to boat transoms. Improper installation of the outboard can cause performance and reliability issues that can lead to safety concerns.
  • Page 84 INSTALLATION BOAT TRANSOM HEIGHT REQUIREMENT 1. Measure the transom height of your boat. The boat bottom should be aligned or be within 25 mm (1 in.) above the anti‑ventilation plate of the outboard. Anti‑ventilation plate 27151 INSTALLING OUTBOARD ON TRANSOM 1.

  • Page 85: 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.
