The Sierra 23-3602 is a replacement thermostat made for Westerbeke engines. Sierra gives Westerbeke 37387 as the number it is interchangeable with. No opening temperature, size or engine model is stated for it. That means the Westerbeke 37387 cross-reference is the thing to check against the thermostat already in your engine before fitting it.
Our take
The Westerbeke 37387 cross-reference is the one concrete fit detail given for this Sierra 23-3602 thermostat. If that is the number on your old thermostat, it is the match to look for; if not, nothing else here says it will fit.
