I saw going down the road today on a trailer an aluminum sit down Jet Ski. I donít know if this was a home built machine a production item. I didnít notice any labels on it but it was going in the other direction, but defiantly aluminum. If this was indeed the case, what a genius machine. Has anyone out there seen something like this? I googled the net and found liners for jet skis made of aluminum but not the entire haul.
