We suggest that you make a speed and RPM chart to obtain the most economical operation.
Operate the boat at various speeds and check the fuel consumption. Compute the amount of
operating time remaining when the fuel gauge has only one bar remaining on the display. Make a
log of this type of information and have it available when using your boat. Other statistics you may
want to determine could include the following:
• Minimum speed for effective steering.
• Turning radius at different speeds.
• Response to steering at low speeds.
• Accelerating and deceleration rates.
• Time and distance to bring the boat to a stop at different speeds.
• Control of the boat in close quarters.
• Time required to bring the boat on plane.
Also read the section in Sportfish, Cruisers, Yachts Owner’s Manual beginning on page 59 for
information on safe operating speed.

Twin and triple engine boats are easier to maneuver than single engine crafts. However, they
still require practice to ensure comfortable operation. The boat will run ahead or backward in a
straight line when multiple engines are working together at the same speed. The engines also can be
used to steer to port as well as starboard. Moving ahead on one engine will cause the bow to swing
away from the running engine side and to move forward at the same time. Backing up with one
engine will cause the bow to swing toward the running engine side and the boat to move backward.
With twin engines, running one engine ahead and one engine astern will cause the boat to turn end-
for-end in little more than its own length and running multiple engines in the same direction at
different speeds will cause the boat to move in the direction dictated by the faster engine but its
influence will be modified by the slower engine.
