Engines; Engine Inspection; Engine Start Procedure - Bayliner 3388 Operation Manual

1.1 ENGINE COMPARTMENT. The yacht is powered by two 150 horsepower Hino diesel
engines. The two large hatches in the cockpit floor provide access to the engine
compartment. The engine hatches have round silver pulls flush with the hatch cover to use for
opening the hatches, and have hydraulic pistons to support the hatch after it is opened. To
close the hatches, use the round silver pulls to gently ease the hatch down into position.
1.2 ENGINE INSPECTION. Prior to starting the engines, complete a "COBBS" check - -
Coolant, Oil, Belts, Bilges and Sea Cock/Strainer.
Check the Coolant level in the recovery/expansion tanks. The tanks are located in
front of the engines, and should be about half full when the engines are cold. The port engine
tank is inspected by lifting up the top of the narrow cabinet against the aft bulkhead in the
lower port-side stateroom.
Check the general condition of the Belts, hoses and fuel lines. Please report any
concerns or problems you find.
Check the Oil level with the oil dip-stick - - use a paper towel to wipe off the dip stick,
and add oil ONLY if the level is at or near the low mark. DO NOT OVERFILL.
Check the general condition of the Bilge areas - - that there is no excess water
collected, and that the bilge pumps and automatic floats switches appear free and operating
properly. Report any concerns or problems you find.
Check to confirm that the Sea Cocks are fully open for sea water cooling to the engine
heat exchangers, and that the Sea Strainers are clean. A flashlight can be shinned through
the glass sidewall of the Sea Strainers to verify that the strainers are clean.
Also - - Inspect the glass bowls under both fuel filters. If a bowl shows any water or sediment,
open the petcock on the bottom of the filter bowl a few turns and drain he water/sediment into
a container for disposal; and Confirm that the Engine Battery Switch is in the ON position.
This switch along with other batter switches) is mounted on a board located between the two
cockpit engine hatch covers.
1.3 ENGINE START PROCEDURE. Confirm that the Master Switch on the DC
Electrical Panel is turned ON so there is power for the engine ignition system.(Electrical
Panel is located on starboard side at aft of the Main Salon). Use the controls at the LOWER
HELM station to start and shut down the engines. Confirm that the Transmission Gearshift
controls are in the NEUTRAL position (or the engine cannot be started because of the "neutral
lock-out" feature), and that the Throttle controls are in the IDLE position. The PORT Engine
should be started first. The engine must be PRE-HEATED prior to starting (unless the engine
is already warm). So depress the PRE-HEAT button for 10-15 seconds prior to starting, Turn
the ignition key completely clockwise to start engine. (Note: The Low Pressure Alarm will
sound until the Engine starts and builds oil pressure). After the engine starts, advance throttle
slightly to 750 RPMs for Warm-Up Idle. Repeat this procedure for starting the Starboard
engine. After the engines start, confirm that there is water flow out of the stern exhaust hose,
and monitor the oil pressure (approx 55 PSI at idle) and engine temperature (slowly rising to
approx 175 degrees).
