I had an issue of the overheat alarm sounding with the motor this year. It would never get too high while running down the lake, nor when idling. It would happen when I shut the motor off prior to the thermostats opening up. I replaced the thermostats in it with the correct 130* tstats. Now, it seems to be doing that more often. Could this be more so of a poppet valve issue (blind guess on this)? Or do I just need to run the motor up until the point that the thermostats open up and the temperature is on the decline before I shut down the motor? Thanks
