This isn't the right board for this but I know it will get anwered on here so bear with me. What range do you guys look for on your water pressure gauge in idle or neutral? Mine is reading about 10 to slightly above, is it time for a new impeller? Motor is a 2000 and the impeller has been changed once about four years ago. I think I'm alright for another year as my stream seems strong but I thought I would axe my boyz.
