Flush Kit For Hose

Engine Flush Kit

800 tools and techniques for testing water flow from stern drive to engine cooling system.

This item is a radiator flush kit placed between the intermediate housing and thermostat housing.

This Isolates over heating problems by measuring time it takes to fill a gallon bucket of water. Note 40 to 50 seconds at 650 rpm.

Note the outdrive must be in the water for this test. This same omc tool or fittings can be used for running the boat in the drive way with a garden hose.

Note outdrive should run at idle speed only for setting points and testing.
Note electric shift outdrives should not be left in gear for long periods of time, as electric coils have no way of cooling out of the water.
