The Tides Marine Shaft Seals require that water be supplied to them in order to keep them cool and lubricated.

The water supply must be at a minimum of 1 gallon (4 litres)  per minute at engine idle. As RPM's are increased, so should the water flow.

Tools needed to check water flow:

1) 5 Gallon Bucket with 1 gallon marks.

2) Any watch with a second hand.

3) Screwdriver to loosen clamps.

To test your water flow, loosen the 2 clamps and remove the 3/8"  (10mm) or 1/2" (12mm) hose from the water injection fitting on one of the shaft seals. Cap the fitting with the supplied plastic cap to prevent water from coming in from the outside. Hold the bucket above the shaft seal and put the hose inside. Have an assistant start the engine that you are testing the water flow on and start timing the water flow. Within 1 minute, you should have at least 1 gallon (4 litres) of water or more in the bucket. Have your assistant bring up the RPM's of the engine to make sure the water flow increases.

Shut down the engine and remove the plastic cap from the water injection fitting and replace the hose. Remember to snug the 2 hose clamps. Repeat the process above if you have a dual engine setup.

If applicable, after completing the test on both sides, remove one side of the crossover line and test it in the same manner.

If you are not making at least 1 gallon (4 litres) per minute of water flow, check the fitting where the water is supplied and the hose itself for blockage.
