r1bryant 0 Report post Posted August 2, 2017 I have a new 218 SS and I'm wondering if anyone else is getting data from the air and water temp gauges that doesn't match outside sources of the same information. Both seem to be running about 10 degrees warmer than actual. Quote Share this post Link to post Share on other sites
marfi 0 Report post Posted September 2, 2017 Im portuguese, let me try to understand a litle, what water temp? engine or water outside the boat? If is water outside boat is your engine running?, your engine send hot water trow the exaust to the water, so is hoter then really is, i have thet info on GPS, and that happens to, normally from 5 to 10 degrees, on my pwc also the same, if i turn engines off after a few minutes they read corect. Hope this helps Quote Share this post Link to post Share on other sites
