Q: I have a FH 680v what is the replacement motor for this model

A: There is no direct replacement option available from Kawasaki. You may need to look into replacing your engine with a new Kawasaki 23HP FS691V. The mountings, wiring, muffler location, muffler, shaft and dimensions will all be different on the new engine. You will need to determine whether a change over will be possible, taking all these factors into account.
