Move the THROTTLE to raise the engine speed to 1000 rpm on the TACHOMETER. Warm the engine
for about 5 minutes before engaging transmission. Observe the readings of the gauges. The oil pressure
will register about 50-60 PSI when the engine is cold. The engine temperature should rise slowly.
Note -- If oil pressure is low, shut down engine, and inspect engine compartment and look for possible
cause (for example, loss of oil.) Caution -- If an engine is overheating or there is lack of raw water
expelled in the engine exhaust, stop the engine immediately. Recheck the raw water-cooling system to
ensure the seacock is ‘open’ (handle in-line with valve). Next, check the raw water strainer for debris.
Remove the strainer, clean, re-assemble, and reopen the raw water intake valve (seacock). Restart the
engine and re-check water flow from the exhaust. If water is not flowing properly, the RAW WATER
PUMP may need to be serviced. Seek help.
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
GEARSHIFT
is in the ‘neutral’ position and each THROTTLE
is in the ‘idle’ position. Turn off engines
by pushing and holding “Stop” button until engine comes to complete stop. Then turn key off.
Getting Underway
DISCONNECT the shore power cord (see 110-Volt next page). Close the PORTHOLES, WINDOWS,
and FORWARD HATCH. Turn on your VHF and electronics. ASSIGN crew members their various
positions. Once outside the marina, idle the engines while crew brings in fenders and lines. “Singling up”
lines so they can be released from on board the boat is a good and safe way to release mooring lines.
Cruising
All close quarters maneuvering should always take place at the upper helm. Because Defiant II carries
her dingy on the foredeck—virtually all operating of vessel should take place at the upper helm.
Engage the GEARSHIFTS. Ensure the throttles are in the ‘idle’ position before engaging the gearshifts to
avoid transmission damage. Cruising speed is a maximum of about 2,000 RPMS. If you run at 2,000
RPMS you will cruise at 15 knots and use only 12 gallons of diesel per hour. Your speed will vary
depending upon the weight and load and weather conditions. TRIM TABS can be adjusted for comfort
and visibility by putting in the “bow down” position. Remember to raise TRIM TABS when coming in to
dock or anchorage.
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.
Docking
During docking, use the FLYBRIDGE HELM
for greater visibility. Have your crew make ready the lines
and fenders and give clear instructions on how you will be docking. Often times your crew will need to
step off from the swim step with the stern line. Another crew member will need to be at the bow or mid-
ships to hand over the next lines. You can often request a “Port tie” or “Starboard tie” when getting a
slip assignment.
