Re: 1100 zxi winterizing

Scott. I never even suggested that you should implement my advice in
winterizing service. What I suggest to my customers to have pump inspected
after each season and all I said that it would be good idea for you to
recommend prevention of possible expensive pump failure. I realize that
average person could care less what we say, but there are some people who
use common sense and will take good advise. The liner failure you describing
has to do with electrolysis. How ever there is another enemy facing this
type of jet pump design, it has to do with aluminum  material which
normalizes after certain period of use.
Some mechanics remove locating pins from housing in order to re align pump.
This move could result in total pump failure and possibility of engine
seizure do exist when pump lucks up at high speed.  I'm sure you know how
expensive parts for this pump are. My modification has proven record of
reducing friction and prolonging service life of pump. My original idea was
to implement  front roller baring, but the cost of baring alone stop many
customers in their track. If I recall closest dimension roller baring is
made in Europe and it cost over $200. Regarding See Doo pump, my record is
opposite of yours, very rarely this pump fails, must do when inexperienced
person misaligns parts during oil change.
