2006 twin 150’s with 170 hours…at 3800 rpm cruises at 28-30mph and temp gauge stays right in the middle (5 electronic gauge bars with middle being the third bar), at 4000 rpm moves up one bar (4th bar)so that would be middle high. Next bar up would be the high hot. Just a little nervous running middle high. Comes back down to middle bar at 3800 rpm fast enough after running 4000 rpm…Is this truly getting hot or is that stilla good safe zone? Just had pumps/thermostats and impellers replaced…could any yami owners or mechanics give some input? thanks…
