Normal Exhaust Riser Temp ZR6

[Providence]

Greetings from rainy Canada,

Trouble shooting Raw water pump issues....does anyone know what the normal operating temp of exhaust risers should be on IR heat gun? Replaced my manifolds and risers and trying to trouble shoot cooling system issues.
Max temp?

Many thanks

I've been meaning to take readings on my running temps for a baseline. Keep forgetting to throw the gun in the boat.
I was going through something the other day and found limp mode temps for an H5/H6, I would think similar for your rig, maybe? Doesn't indicate normal operating temps.
I'll circle back around if someone doesn't pop in with more insight.
Have you checked the manual section to see if it is listed in there?
