„This product is used in a sailing boat 12 meter, with a double prefltration, system 5micron paper and 5micron higher density carbon filter.
This product should be maintained every 2 year by changing the special water seal and ball bearing to avoid any interromption and damage inside the stator housing.
I did not do that and I damaged the motor it self. It was my mistake of corse and mistake of SVB by not supplying spare parts. This part sold in pack of 4 kits (seal and ball bearing ) quite enough for 10 yers minimum.“
