guys,, got powerhead rebuilt and Im questioning what should the head temps be of my 96 112 spl? Im going to a lake today or tomorrow and I borrowed a infrared thermometer. By touch, I can tell upper starboard (1?) is a little hotter than other heads. I can hold my fingers at least five seconds,,, but other holes seem cooler. This is all on flush muff in driveway for 30 mins, diff rpms. Ill get exact temps and post,, just want to know ranges I should see, and when is it time to shut her down. Dont want repeat trouble, #1 piston blew apart. Thanks, Joe
