so last year I put the boat away in the garage in September, and first trip this year in March I noticed the gauge would go from 10 psi to 20 psi every few seconds while running around 4k rpms. anything below that it held steady and at WOT it was reading a steady 25+. I have a new gauge coming in from Triton under warranty, 2021 TRX 18. If there was a freeze issue, which i have never had in 20+ years of owning a boat in VA, would the screwy reading be because there is a cracked hose or the actual gauge froze and broke? I am trying to figure this out or tell the dealer to, I would hate to have them put the new gauge in and it still be reading wacky. They seem to believe the gauge is defective. Anyone ever had one freeze? What were the symptoms?
