Do I have any recourse?

I purchased a 1989 boat thru a private party which broke down the second day after the sale and will now need to spend $3500 to have it repaired. I did demo the boat but wasn't able to fully test due to rough wheather (I know no excuse).

Questions

In the state of NY does the As-IS law apply?

Does the seller have any legal obligation to warranty the engine for a certain period of time?

I'm considering suing the seller on Ill will as he was not honest about the boats condition.

Do I have any recourse? Or am I a born loser... I'll be naming the boat NEVER AGAIN.

NEVER AGAIN

You said, the seller was not honest about the boats condition. If the seller made untrue representations to you that induced you to purchase the boat, and you can prove it, you could sue to rescind the contract or sue for damages.
