I have a Sevylor inflatable kayak in very good condition -- only used a couple times -- air pump, fittings, patch kit, pressure gauge, 2 paddles and bag included
The right main tube has a very slow leak so that needs to be looked at
It is not made anymore by the manufacturer but here is a descriptive page on the particular model:
Features
Crafted from durable, puncture-resistant Sevytex®, a strong polyester with a dual-laminated PVC shell built for years of faithful service
Twin I-beam hull design is self-bailing for whitewater use; bailing holes can be plugged for use on flat- or cold-water excursions
Capable of better speed than short kayaks, the XK17 can carry up to three people comfortably (with optional seat)
Ideal for longer trips or expeditions, it can also function as a reliable dinghy
Moderately rockered shape provides good performance on rough water; directional strakes aid tracking on flat water
Includes two padded seats with back support; water bottle holder and fanny pack pocket on seats to stow accessories
Remove second seat and use center seat position for solo trips; either mode allows ample stowage of gear via bow and stern D-ring tie-downs
Bow and stern spray decks feature rings for attaching rope handles for easy transport of kayak to and from the water
Removable drop-stitch floor offers comfortable support and insulation, and is built tough to withstand penetration
Padded footrests on floor provide paddling comfort and aid in bracing maneuvers
Optional thigh braces and foot-controlled tracking rudder available separately
Twin I-beam chambers inflate to 3 PSI; floor inflates to 7 PSI for unrivaled rigidity; includes pressure guage for verifying chamber pressure
Air-tight Boston valves provide reliable performance and easy inflation and deflation
Includes large nylon duffel for storage and transport and double-action riverboat pump for rapid inflation and deflation
