RAW WATER ALARM***
Mariah is equipped with a raw water alarm located at the helm. The alarm will activate a
light and a horn when the temperature of the wet exhaust pipe starts to increase toward and
unsafe level. This could occur if the seawater intake or the sea strainer become clogged
with vegetation or other debris. The alarm will trigger before other indications of overheat
occur thus saving costly engine damage. If the alarm sounds and you are not threatened by
immanent grounding, shutdown the engine and investigate.
1.
Check the sea strainer and clean if required.
2.
Attempt to operate the boat at a reduced rpm.
If the alarm continues it may be a failed raw water impeller. This is unlikely as they
are replaced annually. However, should it fail, there is a replacement
impeller in the spares bin in the engine room. Call San Juan Yachting on your cell
phone or VHF channel 79a and request assistance. The tender can be launched and
used to tow Mariah if there is no other option.
RETURNING TO DOCK
Fenders out and….
•
On docking side of the boat, (port side is only used because of the dinghy
outboard)
•
At appropriate level for the dock.
The engine cool down period (the last 5 minutes) should be at slow speeds to allow the engine to
cool down before shut off.
1.
Once docked and the mooring lines are secure, turn off the engine.
2.
Shut down the Ray Marine multifunctional displays by
pressing
the red power button
in the lower left corner
and holding
for the countdown on the screen. Please re-place the
screen covers on all the screens as direct sunlight can damage them.
3.
There is no need to turn off the breakers at the DC POWER breaker panel next to the
helm station.
Do not shut down electronic equipment ie. Chart plotter or depth sounder
with the circuit breakers...use the red power buttons or damage could occur.
•
Note: The autopilot wireless remote control is recharged by a cord located below
the dc power plug on the starboard side of the instrument panel. The battery
charge state of the remote can be read on the left side of the screen and is
represented by a number of bars. The autopilot c/b must be on for power to
charge the remote. Depending on use, one charge should last 2-3 days.
Remember to turn the remote off by pressing and holding the © button while the
unit counts down. Use the same button to turn the unit on.
•
CAUTION: If using the remote outside of the pilothouse please use the attached
lanyard and wear it around your neck. The remote costs over $400 and could be
easily lost overboard.
