When you're shopping for a used boat in the boats personal watercraft market, you're often deciding between two very different priorities. On one side, a 2006 Four Winns Horizon 198. On the other, a 1990 Supra Mariah, a ski boat that has been refreshed. Both are American-built used boats, but they are built for different days on the water.
Quick verdict
If you want a turn-key setup for family days, wake sports, and towing, the Four Winns package is the lower-priced choice. If you want a dedicated ski boat with newer cosmetics and a familiar engine, the Supra Mariah offers a more traditional ski-boat experience. A $1,500 price gap separates them, so the real question is which trade-off matters more to you.

Where each boat wins
The Four Winns Horizon 198 wins if you want a tow-ready bowrider
The 87-hour Volvo Penta with SX outdrive is a strong selling point. You also get six LED lights and four large speakers. This is a setup that can pull a wakeboard or serve as a family cruiser without much extra shopping.
The Supra Mariah wins if you want a classic ski boat with updated finish
The 21-foot 1990 Supra Mariah has new gel, a new rubber rail, and upholstery and carpet in good shape. The 351 PCM Cleveland Block inboard makes it a purpose-built ski boat with an open, clean layout. Fresh-water use adds to its appeal.
Product notes
Four Winns Horizon 198
The strongest reason to choose this package is the 87-hour Volvo Penta and SX outdrive, which is unusually low time for a 2006 boat. The factory foldable tower, six LED lights, and four large speakers are already in place, so you can spend more time on the water and less on accessorizing. The bolster seats and interior are impeccable. The catch is a cracked port-side manifold that was installed as a refurbished part; the other side is good. A full tune-up with new filters, fuel pump, water impeller, USCG lines, and battery has already been done. If you can handle the manifold repair, you get a low-time boat with useful extras.
Supra Mariah 21'
The main reason to choose this boat is the fresh gel, new rubber rail, and good upholstery and carpet, all in a one-owner inboard. The 351 PCM Cleveland Block has 785 hours, which is a lot more than the Four Winns, but the inboard design is straightforward and familiar to many mechanics. All stainless hardware and a Trail Master with new tires are part of the package. It has been stored indoors and used in fresh water, which helps explain the condition. If you want a dedicated ski boat with classic styling and updated finish, this is the one to give a close look.
Final choice by use case
Choose the Four Winns Horizon 198 package if you want a trailer, an open bow, and a boat that is ready for family cruises and wake sports. At USD 6,500, it leaves room for the manifold repair. Choose the Supra Mariah if you want a classic ski boat with updated cosmetics, stainless hardware, and one-owner history; at USD 8,000, you're paying for a boat that has been stored indoors and refreshed rather than rebuilt. Both are used boats, so a mechanical inspection before purchase is a smart step.
