My jet ski wouldnt run because it said overheated? - jet ski service

We have a new Kawasaki Jet Ski only last June.
We Service and the winter Izing in October.
the nature of the scene, said it would be just as ready for gas and everything.

My nephew was the jet-ski on it and said he began to steam and whistles like crazy and had to put in.

Why is he?
