Im going on the bay tomorrow and i was just running my motor off the muffs for a few min and there is a strong tell-tale and plenty of water coming out of the center hub. My question is: Is it normal for the left 2 cylinders to be a lot cooler than the right? From the back of the motor the housing around the spark plugs on the left is pretty cool and on the right its a lot warmer. I can still keep my hand on it everywhere without it burning me but is that normal?? I Just assume that the water passage goes through the left side first then the right side. I noticed that a few months ago also and im just wondering if its good to go or what?

with good water pressure and normal operating T-stats both sides should be within 5*s.
