REELPROPERTY (7/23/2008)I have twin OX66 250's 1997 model. My starboard motor runs perfect at any speed but as soon as I get toidle it starts to creep up and gets hot...... The pee stream has always been weaker on this motor but it didn't have any negative effectsuntil now. I have had the thermostats changedtwice and the poppit valve changed twice as well......... Does anyone have any ideas as to what I can check?? I appreciate any advice or help.. Thanks, Jason

Did you change the spring on the poppit valve or at least take the old one out give it a good stretch and reinstall? I know you said you changed it twice but this is such a classic poppit valve symptom it is hard for me to think what else it could be. When it starts getting hot I bet you can give it some gas and it will cool back off right? Also what is your in gear idle rpm? I had mine go down to 400-500 before and it wan't pumping enough cooling water at that speed at 600 it would.
