I have had my polaris slt 750 for 2 years now and never had a problem. Now I can start it without the lanyard plugged in and the kill switch does not work. Still runs great but I dont want to run in without this important safety measure working. Any ideas.....? My seadoo spi fills up with water when it's running in the water but only when it's running, can't figure this one out either but one problem at a time!
