I just bought 2 kawasaki 900 stx jet skis. They came with a really nice trailor to haul the both of them. I paid $2300.
Both of these skis are in pretty rough condition. They say outside their whole life. However, they only have 70 hours on each of them. Is that good? Under the seat the engines look pretty clean..
One of them runs. But maxes out at about 37 mph. I was under the impression these things went a little faster than that. It also spits a good deal of smoke out the back: Im not sure if that is normal or not.
The other one just won't start. I emptied the gas and put fresh 93 octane in it but it just keeps cranking. No Start. I looked at the fuel filter and it is only half full, whereas the one that runs has the filter all the way full of fuel. Im not sure if that is relevant or not. The guy I bought it from said they were on the water running around and they were both working fine. Then the one died. I checked the gauges and the display said it had a half tank of gas.. but it was empty when I checked the bow. I was hoping it would start right up when I put some fresh gas in it. No such luck.
My questions are:
Did I overpay?
What kind of oil do I put in these?
Why is the one that runs so slow?
What are some good ideas to troubleshoot what might be wrong with the one that won't start.
THANK YOU FOR YOU TIME AND PATIENCE. I am a mechanic for the navy but I am just not familiar with these types setups... or any boats for that matter ironically.
