I took the pump off to have a look at the impeller yesterday. Of course, I didn't mark which way was up before doing so. It looks like the hose connects on the pump are not centered. Can someone take a photo of theirs so i can make sure i have this thing right? Gonna run it in the driveway first as well to make sure

Tested today. Outlets go on the right side of the pump if viewing from the front of the engine. Hoses fit better this way too :)

I made the same mistake, impeller housing got extremely hot, manifolds were really warm as well. opened up the impeller to inspect and make sure it was still ok (it was) reversed the pump and cools like a charm.

Thanks for the help. Glad I second guessed myself before having to deal with it in the water.
