Engines

1. Remove the 2 wire temp sender from the air compressor and install 4 wire

temp sender P/N 13536A14.

2. Install wire harness P/N 84-88824A4 between the 4 wire temp sender

under the temp sender retainer bolt.

NOTE: Harness P/N 84-88824A4 is the single Tan wire which is normally

supplied with the gauge. The eyelet connector will need to be removed, wire

cut to length and a bullet connector installed at one end. Available later this

year will be harness P/N 84-11149A50 which has a single tan wire with a

bullet connectors at both ends. Using this procedure to install an analog

temperature gauge will not effect the operation of the System Monitor or any

of the SmartCraft speedometer or tachometer functions.

and TAN wire have been installed on the outboard at the factory.

Replacement of the temp. sender and addition of the TAN wire are NOT
