Dink is too heavy, dealer gave wrong weight.

[CSY Man]

Bought a Mercury Hypalon 310 Airdeck a few months ago as the dealer promised the weight was 80 lbs, not the 103 listed on Mercury's web page.

The boats boxed weight is 87lbs. We have informed Mercury of the weights being wrong on their website and they are working on changing it. The boat does weigh 80lbs.

Thanks

Based on that I ordered the dink.
Guess what, it is really heavy and too much to lift on and off the foredeck.
Called the factory today and they confirmed 103 lbs.
Called the dealer and he says no, he got the weight from the factory so it must be right.

Now what?
Small claims court? Trash the dealer all over the internet?
(Asked him for a refund of all money, shipping both ways plus sales tax and registration fees, etc, etc., but have not heard back.)

What would you do...?

(Besides towing the darn thing all the time.)
