496 running warm
My 496's are running at almost 190. I know this isn't normal and I'm running out of ideas of what to check. Sea water pumps are brand new,oil coolers are clear and heat exchangers are clear. Where do I go next?

You need to use a scan tool to verify the engine temp, read the seawater pump pressure and the port and starboard manifold temps. Go from there. The pump pressure should be around 2.2 PSI at idle and a minimum of 20 at 4000 rpm. Maybe a new thermostat as well.
