Take it out on the water and try it. If you still have probs get an infared temp gun and check your head temps then. I don't trust temp gauges.

170 and 180 is high ...I have analog gauges with the factory recommended senders I have NEVER seen higher than 145 at idle in the Florida sun. 135 at wot. Boobie is correct you may need to use a laser thermometer to verify, cheap and handy from HF ...
