Marissa Was Interested in Buying a Used Personal Watercraft from Victor

Marissa was interested in buying a used personal watercraft from Victor. He told her that the engine on the watercraft was in good shape. Marissa agreed to pay Victor $4,000 for the watercraft. Marissa was going out of town on vacation, so they agreed that when she returned in a week, she would pay Victor and pick up the watercraft. During that week, the manufacturer notified Victor that the watercraft was being recalled because it had a faulty engine. Victor said nothing about the condition of the engine or the recall when Marissa came to pick up the watercraft. They chatted about other matters; she gave him the $4,000, and took the watercraft. Later, Marissa started having problems with the watercraft and found out that Victor and other initial purchasers had been notified of the issue with the engine. She asked for a refund, accusing Victor of fraud. Victor refused on the basis that he did not make any misrepresentation. Who is correct and why? For purposes of this question, assume that sales talk or puffery is not at issue.
