EGT Probes
For Rotax engines two of the four cylinders are usually monitored for EGT, you can select to monitor all four
EGT’s of desired. If only two EGT probes are used they should be mounted on the two rear cylinder’s
exhaust manifolds for proper temperature comparison.
See EGT Clamp Style Probe Installation for instructions.
Boss Mount EGT Probes
Some Rotax engine exhaust manifolds are drilled for boss mount EGT probes. If your engine has boss
mount EGT locations use our optional P/N: 40,202 Boss Mount EGT Probe.
Once you have the EGT sensors installed you
will need to configure the Engine Type to
“ROTAX 2 EGT” or “ROTAX 4 EGT”
RPM
The Rotax engines have a 5
th
trigger coil for RPM monitoring. The trigger coil outputs on a two-
wire harness. Connect one of the two wires to ground and the other to the supplied 33K
resistor, the other end of the resistor than connects to the P/N: 71420 R Rotax RPM interface
board yellow wire. The Rotax RPM interface board is a small heat shrinked module and should
be secured on the inside of the aircraft. If you are using the P/N:71420RX you do not need to
install the 33K resistor.
