My Seloc repair manual for my 1997 Volvo Penta 4.3L with and SX outdrive

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!


PS - I assume you know the 140 degree therm. is the more popular therm.
for merc., but even Merc. makes engines that uses a 160 degree therm.
I guess he has a one thermostat fits all policy. I am amazed he would
do this for a customer who had just had a major service problem due to
their negligence.

I would very quickly find a Mechanic/Dealer who services lots of
Volvo/Penta's, or this will be an on going problem.

That's my story and I am sticking to it!

He is a certified Volvo Penta mechanic.

Sorry, but I really don't know what sort of mechanical or boating
background you have and I do not trust your opinions. Perhaps if you
would be more open on your boating experience and boats you own/owned
folks may be more trusting of your advice. Until then I assume you
have never stepped foot on a boat.

So can anyone address my original questions?
