Couldn't tell you the top speed that pre-dates my knowledge. However regardless of how fast it is your talking about a 32 year old ski. I wouldn't trust something that old. Unless it is almost free sounds like a bad investment. Parts will be scarce.

 

1979 KAWASAKI JET SKI 440

 

So long as it runs well sounds like a fair deal. I would't think it would be any faster then 35 mph. But the first major failure will turn it into scrap. As long as you know this going in you won't be dissapointed.

 

Keep in mind, thats one of the very first ski's. I think it was either 78 or 79. I sold my 90 550 for 500. If your mechanical, go for it, but if you can spend a little, get a little more

 

Should I pay alittle more and get this one 1991 KAWASAKI STAND UP JET SKI 550 SX

 

For $250.00 more get the 12 year newer ski. Thats good money spent as long as it runs well. That one might hit 40 mph. Still the first major breakdown and it is scrap. So have the right expectation level.

Good luck with that ....

 

That 91 is the second year of the good hull, rear exhaust, it's a little wider, and the sponsons are supposed to be better also. It is also the first year of the good motor, reed motor. I would go with the 91 myself

 

On going to go for it

 

If I get the 440 and it blows up could I sell it for parts to get some of my money back
