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.

Raw-water cooled or FWC (with heat exchanger)? I'd say if FWC, definitely
go with 160. Raw-water, I donno - I guess you should be OK if you're in
fresh water...
