Odd boat companies

Mine is a 1978 18' with a 403 Olds. It's not fast by any stretch of the imagination, with my hardest pass on the lie detector showing as 59.6, which ain't bad at all for a 250hp small block. However, how many 18' jets do you know that can seat 6 adults and still have room for a full size cooler, tube and skis?
Mine handles the chop very well, especially if I trim the diverter for the conditions.
As far as being from Wisconsin, that's where mine came from as well. The manufacturer's plate shows that it was made by Ski Boats of Wisconsin, which is also out of business.
Don't try to make the boat too fast. 70 is about the safe limit due to the hull design.
