My Seloc repair manual for my 1997 Volvo Penta 4.3L with and SX outdrive
says the engine takes a 160F thermostat. That is what I installed in

The mechanic who worked on my boat after the overheating incident says it
takes a 140F thermostat and that is what he installed.

Does anyone know the correct thermostat temperature rating for this engine?

Will running the wrong thermostat temp have a negative effect on the
engine's performance?

TIA!


JimH,

I have always followed the mfg'ers recommendations, it just makes sense
that they know the best parts for their engine. Volvo recommends a
thermostat in the 160-170 degree range. It might not be the case, but
when a mechanic, especially one who forgot to change my impeller in the
spring, recommends something different than the mfg'er I assume it is
because that is what he has in stock.

I know I would be looking for a new mechanic.
