"Twin 1984 Crusader 454’s, Gen
"Twin 1984 Crusader 454’s, Gen IV, fresh water cooled.
Starboard engine temp. is 160F at idle and low speed, 180 at cruise.
Port is 140F at idle and low speed, 160 at cruise. I would like to see 160F here at low speed before winter layup.
Changed the port T-stat with a Crusader 160 degree T-stat. No change, port motor still at 140F. Cleaned the connections at the port motor sending unit, no change. Switched the sending unit connections at the gauges, port gauge now reads 160F and starboard gauge reads 140F, so gauges are good. Went to ebasicpower website and had a look at the T-stat housing:

Looks like there are two T-stats and upper and a lower one, which doesn’t make any sense. I replaced the upper T-stat near the figure 8 gasket with the new 160F Crusader T-stat and got no change.
Should I have put the new T-Stat in the bottom location where the housing mounts to the block?
Should I buy a new sending unit? The existing one looks like a resistive element that grounds to the block, and appears to be working."
