Got a good deal on a fully functional 1987 Funjet.. was looking to make it a little faster but running into a lot of trouble finding parts.. It's got the suzuki DT60 2 cylinder 800cc motor, which runs great, but it seems like a 60hp mini boat should be faster. I know in the 90s they went to a yamaha 70+ hp motor but I can't even find them for an engine swap.. these run on the same principle as a jet ski, so there's gotta be something I can do.. anyone have any suggestions?
