The propeller is more difficult to turn as usual

Try to make the following test, before contacting your Watt&Sea dealer :

THIS TEST MUST BE CONDUCTED WITH HYDROGENERATOR OUT OF WATER

-       Disconnect the hydrogenerator from its converter
-        Shaft should be easy to turn without sticking points (i.e. Torque < 0,3Nm)
-        Short 2 phases among the 3. (If an external plug is mounted, man can use a bit of wire to short the contacts )
-        Turn the shaft by hand. You should feel sticking points
-        Repeat operation for the 2 others phases combinations.

       
Possible problems
A    There is still stickings points even when wires are not short -->1 phase is short, check cable integrity
B    Shaft is easy to turn and there is no sticking points --> 1 wire is cut, check cable integrity
C    Shaft is difficult to turn and there is no sticking points --> all phases are short, check cable integrity
