Main Engines
Before starting the engines, do your daily inspection.
1.
Ensure GEARSHIFTS are in ‘NEUTRAL’ as the engines
cannot be started because of the “neutral lockout”.
2.
Starboard engine goes first
3.
Turn the key clockwise partially until the ENGINE
ALARM sounds and
pre-heat the engine for 15-25
seconds for a cold engine
; only 5 seconds for warm
engine.
4.
Then turn the key fully clockwise to engage the starter.
5.
Once started, and while in NEUTRAL, PULL THE
THROTTLE LEVER BY THE BASE STRAIGHT TO
THE SIDE and increase RPM’s to warm up the engine @
950 – 1000 rpms.
6.
Check oil pressure and charging voltage for proper operation @ 950 - 1000 rpm
7.
Check the engine exhaust for both WHITE STEAM/SMOKE and exhaust WATER.
a.
Shut down engine immediately if there is an issue
8.
If all is well, repeat procedure for PORT engine
9.
Turn DC panel switches for the Blowers to ON.
a.
(3 switches total - main blower switch in upper left and 2 switches on the right hand bank)
10.
Warm the engine for about 5 minutes before engaging transmission.
11.
Observe the readings of the gauges.
a.
The oil pressure will register about 30-40 PSI.
b.
The engine temperature should rise slowly.
Troubleshooting TIPs:
If the starter does not engage when the key is turned, move the gearshift lever slightly until you find neutral and try
again.
If oil pressure is LOW, shut down engine, and inspect engine compartment and look for possible causes (for
example, loss of oil.) If the oil pressure needle is bouncing all over the place, a metal fragment may be stuck in the
oil pressure sending unit. This is usually a temporary problem. If the oil pressure is truly low, you should hear an
alarm similar to when pre-heating at startup.
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). If open, close and
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 by calling AYC first.
If the engine cranks too slowly or fails to turn over, check the condition of the battery on the ELECTRICAL
PANEL. If the battery is low, run the generator for a while, or try the BATTERY PARALLEL SWITCH (located
beneath the first stair in the salon and in the panel in the aft stateroom) to connect the other engine battery. TURN
OFF AFTER USING!
