It seems most new boats have a 160 thermostat these days. I have a '93
Mercruiser 4.3LX. Can I use the 160 thermostat? I boat exclusively in
fresh water. I want to get the cleaner combustion that the higher temps
give.

160 is OK for fresh water usage but not for salt water.

Salt will have a bigger tendency to plate the inside of the engine with the
higher temps thermostat.

Salt begins to precipitate out of solution as temperatures increase
and will cause clogged cooling passages.
