Re: 1100 zxi winterizing

Scott. Try to use your brain and common sense. I do not perform service
work. I teach engine designs, machine shop procedure and I build custom
engines. My customer base consist of group of people who experienced
catastrophic failure of the equipment and are looking for longevity and
prevention. By the time pump noise is detected  many times it is to late to
prevent expensive jet pump damage. Yes I strongly recommend to repack new
bearings with quality high temperature marine grease. Must bearings are not
designed  for marine application, they are packed with lubricants to be used
in land.
I do not suggest that you drag your customers in your shop and rip in to jet
pump. I do suggest to inform them in possibility of high cost parts
replacement in case of failure. Consider parts replacement such as shaft,
impeller and housing, it makes sense to look  inside of the pump after each
season. It is good practice and it feels great to know that you have done
your part in prevention. It is customers decision to do what he wants, not
yours or my. In my opinion Kawasaki should have use roller bearing to
support heavy trust of the impeller. I have seen  units with expensive high
mod engines suffering from loss of power due to  induced drag of the
partially damaged jet pump ball bearings. Ball bearing designed to absorb
vertical trust of the shaft, they do not perform well in horizontal  trust
application. You do what you like and I will do what I must. One thing is
certain HPT  Sport USA jet pump modification has proven record of prolonged
service life and decreased power loss due to friction.
