Re: Anyone seen another boat like this?
Allot of tri hulls, of that vintage, used a very similar design. Siverline, Browning, Starcraft, Thompson, Reinell to name a few.
At this point (age) the brand makes very little difference. It's value is purely dependant on condition.
That boat has very nice lines, and like most tri hulls, it is inherently stable.
The powertrain is not as popular as MerCruiser for sure. However, it's easier to service and find parts for than an OMC or Chrysler.
The 302 is as durable as any engine in marine service. There were many of them out there and some jet boat makers still install new ones today. They were the mainstay of the direct drive ski boat market for years.
With normal care, it will last as long as anything. Be glad it's not a Volvo engine. Parts are no issue for the 302.
