It was asked but not answered. Do you have water pressure gauges? This is a must check item at this point. If you don't have them, get them.

If you have engine flushes make sure the check valve isn't clogged. I've seen this many times and it's easy to overlook.

It doesn't surprise me, I've read countless threads where people have cooling issues with crossover tubes. Do a search and you'll get some more ideas. Good luck.

water pressure gauges read 15 llbs and each engine is with in a lb or so of the other!

both engines are set up the same one runs nice and cool it's twi is getting hot!

You have a restriction somewhere. You need to find it before something bad happens. Start swapping parts or measure the pressure at various points along the waters path.

Maybe there is a Coney Island Whitefish clogged in your one motor pickups after you nailed that porn star on the deck of the boat.

Rat ... pull the Thermo ......I agree with the other guys ....good place to start .... ..and they do hang ..even new ...
