Had a couple of trips lately where the overheat alarm would sound when running at higher speed (this is a new thing, its been fine). Plenty of water pissing and on the pressure indicator. I did both the water pump and t stats (thats a pain) a couple of years ago. <br /><br />Should I do the water pump first and see if that clears it up? Is two years a normal interval in shallow saltwater to be doing the whole pump kit? Thanks in advance for any suggestions , great website .
