Search the Kelley Blue Book values of marine vehicles in the personal watercraft section of its website. The Kelley Blue Book only gives the retail and trade-in value of personal watercraft and does not carry values for boats and other marine vehicles.
To search for personal watercraft values on Kelley, you must first choose whether you are looking for trade-in or retail value. Choose the year of the vehicle you are looking for, followed by the manufacturers' name and the model of preference.
If you are looking for the Kelley Blue Book equivalent for larger marine vehicles, Nada Guides is an acceptable source for finding the value of boats, and the website is also free for anyone to use.
