200 Mariner

Well the housing and thermos where covered in corrosion and it looks like the last ones were never cleaned out first so the weren't seated correctly. But what do you think would cause the intermittant pulsing of the water coming out? My guess is a bad blade on impeller. I had it running for a few minutes and the heads were warm to the touch so I am guessing that the thermostats were opening. I will try flushing it all out good again and replacing the hoses too. But I'll also give the impeller a shot too. I was doing this in the driveway with a hose and earmuffs with good pressure(if that matters) and again nothing coming out at top until about 1900-2000 rpm. Thanks Blue too!
