thermostat temperature

[BMerri]

I have twin 350's that are raw water cooled. I boat primarily in fresh water but do go into salt water. <br />What temperature thermostats should I be using? I currently have 160's in both engines.

If it ain't broke don't fix it. 160's are fine. Just remain ever vigilant about a fresh water wash down after a salt water run.

143* is Much Better for Saltwater.....

Thank you for your help. I think I will put 143's in place of the 160's. thanks again
