"Looking for advice on temps.
"Looking for advice on temps. Yesterday, I ran 25 miles offshore. For 3 years, my engines always ran at 172 underway. Yesterday, I noticed the port was running a little warmer than usual, 178 at 2900 RPM's. When she ran at 2500 RPM's all was normal. What would cause this sudden change in temps? Should I be concerned? Both engines were running straight for 5 hours and the port never exceeded 178."
