Most boats are rated and certified for maximum load (weight) capacities (refer to your boat's capacity plate). Know your boat's operating and loading limitations. Know if your boat will float if it is full of water. When in doubt, contact your authorized Mercury Marine dealer or the boat manufacturer. Ensure that everyone in the boat is properly seated.
Section 2 - On the Water Be alert. • The operator of the boat is responsible by law to maintain a proper lookout by sight and hearing. The operator must have an unobstructed view particularly to the front. No passengers, load, or fishing seats should block the operator's view when the boat is above idle or planing transition speed.
The power package must be equipped with a gear ratio and propeller that allows the engine to operate at wide‑open throttle (WOT) at the engine's rated speed (RPM). Use of Mercury Diesel engines in applications that do not meet specified operational parameters is not approved.
At temperatures of –20° C (–4° F) and below, use a coolant heater to improve cold starting. • If operating in arctic temperatures of –29° C (–20° F) or lower, consult your Mercury Diesel authorized repair facility for information about special cold weather equipment and precautions.
• Check all applicable items in the Maintenance Schedules and Operation Chart. • Perform any other necessary checks as indicated by your Mercury Diesel authorized repair facility or specified in your boat owner's and operation manual. Important Information—SmartStart IMPORTANT: This power package is equipped with SmartStart. SmartStart performs all appropriate starting operations upon initial start switch actuation.
Check the engine and the transmission, oil filter, oil lines, oil line connectors, and oil pan for leaks. Check the coolant hoses, heat exchanger connections, aftercooler, water pump, and drain fittings for leaks. Locate and correct any problems, or see your Mercury Diesel authorized repair facility if you are unable to determine the problem.
If your boat is considered a high‑speed or high‑performance boat, we recommend that you never operate it at its high‑speed capability without first requesting an initial orientation and demonstration ride with your dealer or an operator experienced with your boat. For additional information, refer to the Hi‑Performance Boat Operation booklet from your Mercury Diesel authorized repair facility.
Section 2 - On the Water 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. mc79555-1 WARNING Sitting or standing in an area of the boat not designed for passengers at speeds above idle can cause serious injury or death.
