A Sierra 142 degree thermostat, number 18-3551, listed for MerCruiser engines. It replaces Mercury 59137 and 807252T1, Chrysler 4142885 and Crusader 96319, and the fit list names CH190 305, CH220 305, CH270 350 and CH350 454 engines. Check the opening temperature on your old thermostat against that 142 degree figure.
Our take
The 142 degree figure in the name is the first thing to check against your old thermostat. The fit list runs by engine, CH190 305 through CH350 454, with cross numbers from Mercury, Chrysler and Crusader to match against the old part.
