Assuming you are referring to the Hobie Mirage Drive kayak propulsion system:
The cost of the Hobie Mirage Drive itself is $749.99. However, this does not include the cost of the kayak or other necessary accessories.
When purchasing a complete Hobie kayak with Mirage Drive included, prices start at around $2,500 and can go up to $5,000 or more for higher-end models.
Besides the initial cost of the Mirage Drive, there are few ongoing costs associated with using it. The only regular maintenance required is occasional lubrication of the drivetrain components (gears, bearings, etc.), which can be done easily at home with some basic tools and supplies.
