CC 350Q Thermostat

I would like to replace my Thermostats on my 1975 350Q's. The old ones have 143 stamped on them. I'm not sure if these are the correct ones. Can anyone give me info on the correct Thermostats to use on these engines. Mine are raw-water cooled.

As a general rule..... the 143's are used when in ocean water to reduce the risk of salt crystallization, which apparently begins at temps around 140*F.
If not in salt water, you can use a higher temp stat.
