I have the oppurtunity to purchase a 2000 or 2001 60" Lazer Z with a new 23hp liquid cooled kasasaki engine installed on it. The deck, spindles, frame, etc. all have 1800 hours on it. It has new belts and blades. It can be mine for around $3000. The price seems good, possibly under powered, but I can deal with it. My question is, how long should I expect the body to keep going? Its been extremely well maintained, from the look of it I would guess it to be only a year or two old, but I know its about 5 years old. I was also wondering why an engine that is supposed to last longer because it is liquid cooled had to be replaced after 1800 hours. If anyone has any experience with this mower and/or engine let me know what you think.
