Glad to see the problem is fixed! I do find it a little odd that the dealer had no issue with the engine running at 180 degrees. As I stated, I have two different manuals for my boat and they both say that the LT-1 should be 160. You had the exact symptom that I had when I tried to run a 160 degree t-stat in place of my 142. Did they give you a discount for bringing this to their attention?
