Having an overheat alarm problem , but it seems it only goes off at odd times here is whats going on: 2008 Sabre FTD 175proxs – 40hrs – 25P Tempest analogue PSI = 2 at idle 14 at WOT Sometimes when new alarm would go off only when getting on plane -if I backed off the alarm would shut off- it seems like the PSI would drop way down then pick up when on plane. Took to my dealer and installed scoops which helped a little . 2 months ago it started happening again took it the dealer , they told me my PSI was fine and the impeller was good. Now it getting worse and my dealer just went out of business . Im in AZ so its hot to start but I still only get the alarm when trying to get on plane never at idle or no wake speed. Any ideas would be appreciated . Also I need a recommendation on where to take it in the PHX area. Thanks
