I am looking going in with my boss on buying a jet ski. A guy locally is selling 2 one is a 2003 Polaris which the guy says runs fine. The other is a 1999 not sure what size think it said 700 something on the motor. It does not run the guy says that it is getting spark but just not firing. What could be the problem with it. He said that the motor had been replaced 3 years ago and he is the original owner. What would be some things to look for? We plan on going to look them over real good maybe the first of the week. They seem to be in good shape structurally. The guy is asking 3000 for them do you think that is reasonable? I was thinking offer him 2500 cash for them he has had them forsale for a while.
