Selling Boat on Consignment

So I bought a boat from a dealership and they agreed to sell my current boat (2002 Supra Launch) on consignment. Other than the fact that they've had the boat for a month and I had to email several times to get in touch with someone...

Is it normal for a dealership to want to fix everything that is wrong with the boat? I knew there were a couple of things (front lights kept tripping breaker and a few other not critical stuff) but they want to fix everything down to replacing the horn ("because it doesn't sound good") and make a custom bow canvas bow cover ("because it might be a while before we sell it"). Grand total on repairs is $2500.

This was never mentioned to me by the sales guy when offering to sell it on consignment and its over 10% of what the boat is worth. I feel like I'm getting bent over here and I wanted to see if anyone else here is familiar with this practice.

Thanks
