143 Deg

This is the Sierra 18-3543 marine thermostat, rated 143 Deg and carried with the BRP reference 435491. Its application list covers 40-250hp E-tech, 6-55hp, CrossV4 and V6 engines, plus the 9.9 and 15 four-stroke models from 1994-01. Check your engine against that list before fitting it.

Our take

The 143 Deg rating is the number to match, and the application list runs from 6-55hp up to 40-250hp E-tech, plus 9.9 and 15 four-strokes from 1994-01. That is a long list, so check your exact engine against it.
