Shopping for a used inboard ski boat in the boats and personal watercraft market often comes down to whether a classic boat has been stored and maintained well enough to trust. This 1990 Supra Mariah is a 21-foot inboard ski boat listed at USD 8,000, with fresh-water use and a one-owner history that starts the story in its favor.
Quick verdict
For the right buyer, the answer is yes. The boat has a composite hull, all stainless hardware, new gel coat, a new rubber rail, and a dealer inspection already completed. The trailer has new Trail Master tires, so you can plan the first tow without an immediate tire budget.
Who it suits
This boat is best suited to someone comfortable with a used inboard ski boat and aware that the fuel capacity is listed at 11 to 20 gallons. If you want a classic ski boat and plan around shorter range, this is a match. Those expecting a turnkey new boat should pass.
What stands out from the listed details
The preservation details are the highlight: stored indoors, a fresh gel coat, all stainless hardware, and a new rubber rail. The 351 PCM Cleveland Block with 785 hours is the engine, and having a dealer inspection already completed adds confidence.
Meaningful trade-offs
The honest trade-offs are age and use. The engine shows 785 hours, the upholstery and carpet are good rather than new, and the 11-to-20-gallon fuel tank will have you planning stops. The phrase "needs a good home" signals that this is a used boat with ongoing care needs.
