Hi, I have two KAD 300 in my 2003 Windy 37HT. Both engines have 450 hours and run perfect. I have discovered that the temp. gauge on the port engine is a little unstable. It changes from 150 - 180 degree Fahrenheit in seconds.... then stable at same level as starboard engine. Important to mention is that it never goes higher than the starboard engine. Like it looses full input and after a second or two the input is fine and it flows back to same level as starboard temp. I have never had an overheating alarm. Do I have a bad sensor ? ....or any other input. Anyone has seen this before ? Thanks for a great forum and help with this.
