Shut-Down
Before shutting down, allow the engines to ‘idle’ for about 5 minutes to cool them gradually and
uniformly. The time engaged in preparing to dock the boat is usually sufficient. Ensure each THROTTLE
/ GEARSHIFT
is in the NEUTRAL – IDLE position. Turn off engines by rotating keys
counterclockwise.
Getting Underway
ENSURE PRE-DEPARTURE CHECKLIST HAS BEEN PERFORMED AS REQUIRED. Ensure TRIM
TAB switches are in the “BOW UP” position. (rock TRIM TAB switches to “BOW UP” and hold for 8 to
10 seconds if unsure) ACTIVATE BOW THRUSTER. Check wind speed / direction, adjust planned dock
line release sequence if necessary. Review departure plan with crew one last time and ensure
crewmembers are ready. Center the WHEEL (e.g. rudders straight) and use only the THROTTLE /
GEARSHIFTS to maneuver the boat. Captain should be standing on the right side at the helm with hands
on the THROTTLE / GEARSHIFTS while maneuvering inside the marina! Once outside the marina, idle
the engines while crew brings in fenders and lines. Always have someone assigned to watch for traffic
and obstacles!
Cruising
Check gauges. Ensure each THROTTLE / GEARSHIFT
is in the NEUTRAL – IDLE position. Increase
throttles to 1200 RPM. To bring vessel up on step to cruising configuration, DELIBERATELY increase
the throttles up to 2400 to 2500 RPM (do not exceed 2500 RPM) Once the vessel is “on step” reduce
throttles to 2250 RPM. Rock TRIM TAB switches “BOW DOWN” as needed. (Full bow down position
takes about 8-10 seconds) Wake should look like picture below:
If wake does not look like picture above and water is roiling over the swim platform, reduce throttles back
to 1200 RPM and repeat procedure above. (Especially with vessel fully loaded and full fuel tanks,
deliberate advancing of throttles is required to bring vessel “out of the hole”) Maximum cruising is 2400
RPM. If you run at 2250 RPM you will cruise at 11-12 knots and use only about 10 gallons of diesel per
hour. Your speed will vary depending upon the weight and load and weather conditions.
Note -- Avoid higher engine speeds as it causes higher engine temperature, possible damage, and higher
fuel consumption. In general, lower RPMs result in much improved fuel economy.
