They came with 2 different temp thermostats depending on area where boat was orignall shipped. 143 deg & 160 deg. Contact Rich @ www.skidim for advise. He really knows his stuff.803-345-0996 is the ph number.

160 with raw water cooling. Holds temp with no variation (99 GT-40...same basic motor).

What did it run at before it overheated??

Another enlightment. Wher the new impeller was put in it was dry run for enought time to heat the casing up, to where you couldn't touch it..
anyone know if this could make the new impeller defective??

It wouldn't make it defective(that would be if it was bad from the factory), it would wreck it though, that heat is enough to melt it, you probably melted some of the sides of the vanes when you ran it dry, i'd say time for another impeller.

i would check your fuel pump too

Ok well it was just a few seconds that the impeller ran dry, but it was enough to destroy it.. the new one has the temp down at 160 max again, thanks for all your help guys.. may the boarding continue..
