I have a 2001 Mercruiser 5.7L with throttle body injection. I've noticed steam coming out the driver side thru hull exhaust but engine temp is fine. The same volume of water coming out both sides of the thru hull exhaust so I'm not to concerned... Anyway, when I felt the hoses coming off the thermostat manifold to the exhaust manifold, the drivers side is always much hotter... Is this hose supposed to be hotter and if so, why?

Thanks!
