86 Maintenance and Troubleshooting
The speed or log readings are wrong –
1.
The paddle wheel on the transducer may be fouled. Clean the parts
as described in the section on “Cleaning Instructions.”
2. Check the speed calibration. Use the item for “Speed Cal” on the
System Setup Menu. See the instructions in Section 2.
Servicing a Thru-Hull Transducer
If your boat has a thru-hull transducer, you can service it without
removing the boat from the water. The sensor(s) are mounted in a
cylindrical plug in the center of the transducer assembly. If necessary,
you can remove this plug by working from the inside of the boat. The
transducer housing includes a check valve to minimize the water intrusion
when removing the insert. A small amount of water will enter the boat.
This is normal. Immediately after removing the speed insert, place the
dummy insert in the transducer housing. Do not leave the transducer
without the speed or dummy insert in place.
