Cruising
GEARSHIFTS/Throttles
–
Ensure the throttles are in the ‘idle’ position before engaging the gearshifts to avoid transmission damage.
–
Move gearshift slowly to point of transmission engagement, either FWD or BACK, then engage more
throttle
–
Be smooth and purposeful with the shifters and throttle
–
Maintain RPM balance between engines
Cruising speed is usually about 1500-1750 RPM and the engine maximum is no more than 2300 RPM’s for short
periods – as in avoiding a ferry bearing down on you.
Your speed will vary depending upon the weight and load and weather conditions. TRIM TABS are adjustable at
the helm if desired. They adjust the BOW, as in BOW UP or BOW DOWN port and starboard. She will ride high
on the starboard side until trimmed out. Perfect trim is when she is riding flat and you maybe pick up a little speed.
Always avoid higher engine speeds as it causes higher engine temperature, possible damage, and higher fuel
consumption. If you run at 2000 RPM’s you will cruise at 10-11 knots and use about 12 gallons of diesel per hour
($35-$40/hour total for both engines) – while maybe only half that fuel consumption at 1500 RPM traveling at 8-9
knots. See below for approximate diesel usage.
Turbo Engines – 5 minute Cool-down required
Before turning off the ignition, allow the engines to ‘idle’ at about 700 RPM for
about 5 minutes to cool them gradually and uniformly. This is very important
since the engines are Turbo charged and the residual oil in the turbocharger needs
time to cool down or it could damage delicate moving parts. The time preparing to
dock the boat is usually sufficient.
Ensure each GEARSHIFT is in the ‘neutral’ position and each THROTTLE is in
the
‘idle’ position. Turn off engines; remove the keys and place in the electrical panel cabinet in the main salon.
Turn Blower switches off after 5-10 minutes to conserve battery.
