GENERAL INFORMATION U.S.
GENERAL INFORMATION The steering link rod that connects the steering cable to the engine must be fastened utilizing self‑locking nuts. These self‑locking nuts must never be replaced with common nuts (non‑locking) as they will work loose and vibrate off, freeing the link rod to disengage.
GENERAL INFORMATION ! WARNING Should the operator fall out of the boat, the possibility of serious injury or death from being run over by the boat can be greatly reduced by stopping the engine immediately. Always properly connect both ends of the stop switch lanyard to the stop switch and the operator. ! WARNING Avoid serious injury or death from deceleration forces resulting from accidental or unintended stop switch activation.
GENERAL INFORMATION Passenger Safety Message ‑ Pontoon Boats And Deck Boats Whenever the boat is in motion, observe the location of all passengers. Do not allow any passengers to stand or use seats other than those designated for traveling faster than idle speed. A sudden reduction in boat speed, such as plunging into a large wave or wake, a sudden throttle reduction, or a sharp change of boat direction, could throw them over the front of boat.
GENERAL INFORMATION ob00314 The primary concern is the boat changing direction while in the midst of the jump. In such case the landing may cause the boat to veer violently in a new direction. Such a sharp change in direction can cause occupants to be thrown out of their seats, or out of the boat. ! WARNING Avoid serious injury or death from being thrown within or out of a boat when it lands after jumping a wave or wake. Avoid wave or wake jumping whenever possible.
GENERAL INFORMATION • The boat could move suddenly in a new direction. Such a sharp change in direction can cause occupants to be thrown out of their seats or out of the boat. • A rapid reduction in speed. This will cause occupants to be thrown forward, or even out of the boat. • Impact damage to the outboard and/or boat. Keep in mind, the most important thing you can do to help reduce injury or impact damage during an impact is control the boat speed.
GENERAL INFORMATION GOOD VENTILATION Ventilate passenger area, open side curtains, or forward hatches to remove fumes. ob00316 Example of desired air flow through the boat. POOR VENTILATION Under certain running and/or wind conditions, permanently enclosed or canvas enclosed cabins or cockpits with insufficient ventilation may draw in carbon monoxide. Install one or more carbon monoxide detectors in your boat.

INSTALLATION Installing Outboard ! WARNING Before operation, the outboard must be correctly installed with the required mounting hardware as shown. Failure to correctly fasten outboard could result in outboard ejecting off boat transom causing serious injury, death, or property damage. We strongly recommend that your dealer install your outboard and related accessories to ensure proper installation and good performance.
INSTALLATION Propeller Selection For best all around performance from your outboard/boat combination, select a propeller that allows the engine to operate in the upper half of the recommended full throttle RPM range with the boat normally loaded (refer to General Information ‑ Specifications). This RPM range allows for better acceleration while maintaining maximum boat speed.
TRANSPORTING Trailering Boat/Outboard Trailer your boat with the outboard tilted down in a vertical operating position. If additional ground clearance is required, the outboard should be tilted up using an accessory outboard support device. Refer to your local dealer for recommendations. Additional clearance may be required for railroad crossings, driveways and trailer bouncing.
FUEL & OIL Fuel Recommendations IMPORTANT: Use of improper gasoline can damage your engine. Engine damage resulting from the use of improper gasoline is considered misuse of the engine, and damage caused thereby will not be covered under the limited warranty. FUEL RATINGS Mercury Marine engines will operate satisfactorily when using a major brand of unleaded gasoline meeting the following specifications: USA and Canada ‑ having a posted pump Octane Rating of 87 (R+M)/2 minimum.
FUEL & 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. Severe engine damage may result from use of an inferior oil.
FUEL & OIL ob01436 3. Reinstall fill cap and tighten securely. Filling Remote Oil Tank (If Equipped) 1. Remove fill cap and fill with the specified oil. Capacity Oil tank 11.5 liters (3 gal.) Fluid Type Mercury or Quicksilver Premium 2‑cycle TC‑W3 outboard oil 2. Reinstall filler cap and tighten securely. 3. Check oil level in the engine oil injection tank.
