Hydrohoist

I am looking at a Mastercraft 205. It doesn't come with a trailer, but the seller is willing to include the hydrohoist that it sits on. I have no use for a hydrohoist, but I must have a trailer. My question is if I can sell the hydrohoist for enough to buy a trailer for the boat. I couldn't find any for sale, so I don't know what they're worth. I don't know anything about the size or age of the lift, but it works and a 205 fits nicely on it. I don't have to have a mastercraft trailer, just a tandem axel that fits the boat. Any idea if I will have any lucky pulling this off?

$100 and i'll pick it up

My new (1.5 years old now)5500lb hydrohoist cost $5000. I see older ones about that size go anywhere from $1500 to $3000.
