9.3 Storing
During storage, the gyro maintains charge in the dedicated 48 V
battery by trickle charging from the house battery bank. To avoid
draining your house battery, plug in the house battery charger
when not using the boat for more than two weeks.
9.4 Winterizing
You will need to winterize the raw water cooling system if the
gyro, or any gyro subsystem, is exposed to freezing temperatures
during winter storage.
NOTICE! Environmental hazard
Discharge of antifreeze into the water is harmful to aquatic
life, and is prohibited in most jurisdictions.
When winterizing your system, do not allow antifreeze
to discharge into the water.
Recycle or dispose of antifreeze according to your local
regulations.
Tools required:
• Marine antifreeze of suitable freezing point for your climate
• Two buckets, minimum 3gal (11.36L) capacity
• Funnel
• Slot head screwdriver
You may need a helper to complete this procedure.
1. Close the raw water seacock that supplies the cooling system.
2. Remove the hose clamps that attach the raw water discharge
hose to the overboard drain. Place the end of the hose in a
bucket.
3. Remove and empty the bowl from the raw water strainer.
Clean all debris from the bowl and strainer, then re-install the
bowl.
Some strainers have a top opening that allow you to pour
antifreeze into the strainer. If that is the case on your boat, fill
the strainer with antifreeze and skip to step 6 on page10.
4. Remove the hose clamps that attach the raw water intake hose
to the seacock. Remove the hose from the fitting and put the
end in a bucket to collect the water that drains out. Once the
water drains, empty the bucket.
5. Put the intake hose back in the bucket and add enough
antifreeze to submerge the end of the intake hose. If the hose
is too short, or there isn't space in the boat to use a bucket,
you can tilt the hose up and use a funnel to add antifreeze
directly to the hose.
6. On the gyro MFD user interface, go to the Settings page (gear
icon) and touch the button labeled "Winterize System" to
activate winterizing mode.
The raw water pump will run for 15 seconds to circulate the
antifreeze through the system.
7. Make sure the intake hose or the strainer is kept full of
antifreeze during the winterizing cycle to avoid drawing air
into the system.
8. Repeat step 6 on page10 until undiluted antifreeze is
coming out of the discharge hose. Watch to make sure the
bucket does not overflow.
9. If you filled the system through the raw water strainer, close
the strainer. Reconnect the intake (if necessary) and discharge
hoses to the through hull fittings and tighten the hose clamps.
Your gyro is now ready for winter.
9.4.1 Returning a winterized gyro to service
This task needs to be done with the boat in the water.
1. Remove the hose clamps that attach the raw water discharge
hose to the overboard drain. Place the end of the hose in a
bucket.
2. Open the raw water seacock that supplies the gyro cooling
system.
3. On the gyro MFD user interface, go to the Settings page (gear
icon) and activate winterizing mode.
The raw water pump will run for 15 seconds and pump raw
water into the system. The winterizing antifreeze will be flushed
into the bucket.
4. Repeat as necessary until only raw water is being pumped into
the bucket.
5. Reconnect the raw water discharge hose to the overboard
drain and tighten the hose clamps.
6. Safely dispose of the antifreeze according to local regulations.
Your gyro is now ready for use.
9.5 Recommended maintenance schedule
The maintenance schedule describes the recommended
inspection and service intervals. In harsh environments, you may
need to increase the frequency of service.
WARNING! Risk of serious injury and equipment
malfunction
Maintenance and service must be performed by a
qualified marine technician.
Remove all sources of power from the gyro before
performing any work with the cover(s) removed.
