Sled was overheating after about 1/2 hour mild riding on lake and trail. Think i had air in rear exchanger, got what air out i thought was there. After few days and took sled out and same thing. Pulled the thermostat and replaced it. Ive attache dthe old one because it was messed up. Wondering what would cause it to do this and if you guys may think the overheating was because of this. Thanks

If ya don’t find one ok to run without. Just give it time to warm up before riding. Make sure running board coolers are warm.

Have a look at the pic in my rebuild thread, mine looked much the same:

I had ordered a new one without looking at it, so it was just pure luck, now they seem to be discontinued though

I've got a spare used one if needed, it works.
The chamber that houses the expandable wax motor/pellet begins to leak allowing coolant into it which leads to early to open and over extension.

Sorry Im not following "wax motor/pellet" could you explain further?
The wax pellet expands with heat and pushes the rod that lifts the poppet valve off its seat. The seal at the rod will leak over time and allow coolant into the chamber when the pellet is contracted. When the pellet expands, the coolant adds to the volume of the chamber thus over extending and also changing (lowering) the opening point.
