Re: 1100 zxi winterizing

George,i think we can agree that skat -trak builds the best aftermarket pumps
available.If there was big hp and speed gains to be had from using a system
like yours dont you think they would have adopted a wet system by now? my ski
puts out 225+ hp with the triple pipe motor installed and has not had a bearing
failure since i have owned it.How many times have i repacked the "sealed"
bearings? not once.Most kawasaki pump related problems i have seen are salt
water damage.mostly the wear ring being pushed into the impeller by a buildup
of salt deposits between the ss wear ring and the pump housing.It has a name
but i dont remember it.Giz would know.Maybe you do.It is caused by two
different metals not getting along.I have seen much better reliability from the
kawasaki pumps than the sea-doo plastic ones.The o-rings on the sea-doo pump
cones fail often letting water in and taking out everything.I have also seen
them crack across the stator section for no reason.It is just not feasable to
pull the pumps out of each ski just to check the bearings.It would double the
cost of winterizing a kawasaki or yamaha.I do change the pump oil in the
sea-doo's as part of the service and install a new o-ring.
