Merc blue motor T-stats
 

So the motors i picked up had the wrong t-stat housings supplied with them, causing too high water pressure. The housings were drilled to create a bypass so now they dont get up to temperature. Found a set of proper t-stat housings, now need to swap them and figure out how water is routed, but cant find a schematic or clear instructions anywhere for untrained monkeys like myself. Anybody have a link to a diagram or clear instructions on how to do it (pics would be great :)

Your exhaust has a dry joint from the manifold to riser so you'll have to run a T fitting of some type.
This is the standard set up for HP500 and 525SC

I think i just found what i need on Amazon, thanks
