I am new to pwc and have recently got a 700 slt, it had been standing for 4 years so after I de winterised it changed the fuel and the oil new battery etc she fired up and ran, I have had it in the water twice the first time for 5 minutes and then an alarm of some kind satring sounding, after checking i checked the oil level, cleaned the oil guage and made sure I had plenty of fuel because the guage is not working. I took her out today and it ran great for 30 minutes and then the alarm went off again, is this a temperature warning and if so what are the things to check to make sure the cooling systm works etc, also when you turn it off after the alram it wont start again, can any of you polaris experts help me please.
