Kawasaki js300 Stand Up Jetski

Kawasaki js300 stand up jetski, it's about 33 years old I've just pulled it out of my neighbours garage after 18 years, it was running before he put it away it does have compression and a spark but I've never had it running, it will need a battery and a check over, it's sold as seen cash on collection no time wasters no postage anyone with low feed back contact me first thanks phone
