2006 225 pro xs 1b243288. I've had intermittent water pressure/temp issues for a long time with No Alarms. I've went through the complete cooling system, complete water pump, thermostats and poppet. On startup/idle I will get elevated temp spike 145-150 degrees then it falls back to 132 degrees and settles with good water pressure 3 lbs via smartcraft. WOT I get 25 lbs psi and temps around 127 degrees. After I come off plane sometimes my water psi drops to .7-.8 psi for 45 seconds to 3 minutes before my water pressure recovers to 2.5 lbs and my temps spike to around 140 degrees. I know my poppet is causing my psi to intermittently not recover. My question is I've replaced my poppet twice. When its new it goes in and out like butter. But as it ages and gets a couple years old the rubber grommet seems like it swells and makes it tight again. Am I missing something here?
