Sounds like you wrapped it up FSTboater. I am going to try the backflushing again in the morning. Last time I only did the oiler cooler, not the hose to the cooler. Then I will go after the inlet side of things. The boat has only been in freshwater.

I will post as soon I get another chance to get to work on the boat.

Ok guys, just wanted to say thanks to everyone, I finally got it figured out. I talked to many people, and they all told me that the power steering cooler was a straight shot through and could not be clogged. Well turns out that is not true, it has some funny shapes in it that will hold an impellor fin really well.
I figured this out by doing my backflushing and just getting a trinkle out of the other end so I started removing all the coolers to run water through them and finnaly found the clog in the power steering cooler. I did also have a riser gasket that was trying to leak a litte so I replaced that also.

Thanks everyone
