110 Deg F at idle is nothing. Very low water flow and heat soak. Rev the engine and watch it go down at idle and up to 143 / 160 under operating conditions.

Temp should be at 143 or 160 depending on your thermostat once warmed up ... 110 indicates likely stuck open and that will impact performance a bit ...

Also Andy soot lime residue on the transom after a day of running it? I used to run my 93 rich but I never had a hesitation when I would punch it ... loved it dialed in, did have electronic ignition on my GT40 even with the Holley carb...

Yeah it's usually right around 143. It has only been a couple of times that I've noticed the 110. Did change anything and took the boat out yesterday and it ran fine so I'm lost haha
