4.5 Impeller Installation

Transom-mount and thru-hull impellers can be used
with the SL150. See section 3 for a list of available
impellers. Specific installation instructions are
supplied with each impeller.
Note: It is wise to check the operation of the
impeller before installation. To check; apply
power to the instrument, plug in the impeller,
spin the paddlewheel, and check the
instrument for a speed/temperature reading.

1. Keep electrical and transducer cables away
from alternator or other noise generating
electrical cables. Avoid connecting the
instrument to power circuits that share loads
with ignition, alternators, inverters and radio
transmitters. Electrical power supply
connections should always be as short as
possible.
2. Connect the red wire to the positive supply
via a 1 amp fuse or a 1 amp circuit breaker.
Connect the black wire to the electrical
ground. A 1 amp fuse will provide protection
for up to five 150 series instruments.
+12 VDC
3. Connect the 4 pin Fuji connector to the speed
Ground /
and temperature transducer cable connector.
-NMEA output
Extension cables are available if the
transducer cable is too short.
4. If you are not using a repeater or you do not
intend to provide NMEA data to another
instrument then insulate the bare wire end of
the blue cable.
The SL150 may be used as an individual instrument
or connected with a number of other 150 series
instruments to the 150 series NMEA0183 repeater
or to other instruments accepting NMEA 0183 data.
