It seems most new boats have a 160 thermostat these days. I have a '93
Mercruiser 4.3LX. Can I use the 160 thermostat?


You probably would not notice a difference in engine performance or
efficiency during normal boating operation. MercCruiser uses a 140 degree
thermostat in the same 4.3 engine that Volvo and the former OMC use with a
160 degree version.
