I have a 2012 ProXS 150 (Serial# 1B934681). What should the operating temperature range be at idle, and a fast idle graphing at about 4 mph?
In gear at idle speed my smartcraft gauge shows mid 140’s to mid 150’s and I can watch the temp go up and down as the thermostats cycle. But if I add some throttle to speed up to 4-5 mph (not sure on the rpms’s) the temp will start rising into the 160’s and 170’s. If I let off and slow down the temp will drop back to 140-150 range. If I speed up faster the temp will also drop. No alarms.
Is this normal? I typically leave the gauge on temp or water pressure and don’t remember it going that high. Water pressure seems normal 1-3 psi at idle and 14-15 psi at WOT.
