When running my mercruiser 198
When running my mercruiser 1980's 350 off the garden hose I noticed that the water running out the manifold on one side would stop flowing water out the exhuast after about 5 minutes of running the motor. I would shut it down and then restart it when water was running back out that manifold and it would run again for a bit with water coming out but stop again. A couple of times it would run fine but the other manifold that wasn't acting up would stop flowing water out. Any ideas? Is this a circulation pump or thermostat problem?
