I think it becomes more of a "problem" when the water gets pretty cold. Ill be running her periodically through the winter.

I am having cooling issues myself at this time, I have read this entire topic in hope of finding a solution. I recently had an impellet blow apart, I think this was do to lake of water feeding it, I had a leaky hose feeding it and have since replaced.
I am hoping I just have the wrong impeller installed, all I could get in a pinch at a local Nautique dealer was a Sherwood. Not sure this one is adequate, I have since ordered a Jabsco from DIM, but have not received it yet.
  Question, Brandon mentioned to be sure you get all the pieces of a blown impeller, I did clean out the impeller housing of all pieces, is there somewhere else I should look ?
I remover the T Stat to be sure that was not the problem but without it I am still running hot. At an idle only, about 210 degress, on a plane , she cooles off fine.
  Till I get this corrected, is it dangerous to idle at 220 ?
Lot of questions, any help would be appreciated.
   Thank-You all,

for some closer, incase anyone is interested......
  today I removed the hose before the impeler housing, ran with it in a bucket of water with a hose feeding the bucket, she never got to hot, so I new there must be some blockage between the impeller and the intake in the hull of the boat.
  I took all the hoses off, prior to the impeller, including the strainer, flushed them out but never found anything. after putting everything back together I started her up and the temp was normal, I presume something was lodged in the hoses or intake and I never saw it get flushed out.
  it was somewere in this 5 page topic that gave me the idea to feed the impeller with the intake hose in a bucket, which lead me to correcting this problem.
  So I thank John  Doerfler for starting this Topic !

Keith,

Pull off the hose that goes to your transmission cooler there is a screen in there and that could be holding alot of impeller pieces. Atleast thats what i have found from my experience. When i first got mine i ran it off a garden hose and it caused the impeller to burn up and thats where i tracked all the pieces back to!
