Will try to make a long story short. Starboard 1988 454 FWC with 1400hrs, bought boat with about 950hrs. This motor always seems to run 5-10 degrees hotter than port and every other year or so this motor seems to have an issue with getting too hot - right now is running just over 180 at 3000rpm cruise - port motor runs a steady 168 or so.
So in trying to diagnose overheat and running heat gun noticed this motor has a hotspot on the left side of carb (see pic) that was up to over 400 deg just in this little 2"x2" area can see. I painted this spot a month ago and already buened off paint. Scanned other side of carb annd other motor and this area only seems around 250-300 deg or so. Mechanic said there is a block off plate at gasket here as is where exhaust is?
So still seems too hot to me and wondering if this might have something to do with this motor always running hotter? Is something need o be concerned about? If yes where do I start?
Thanks Ryan
