What is the depreciation value on pontoon boats?

AS long as you keep the algae off the torpedoes and buff them out once in awhile; not to mention scrubbing the seats and such, repairing any old tears............1500.00 at best|||depends on how many times it's been driven up on the rocks during a drunken outing. And see how many times a drunk had run into it with their Jet Ski. Also, what shape is the outboard in?
