Monhegan 25 Yi Heung is a Lyman-Morse custom 25′ jetboat. She was built to be simple without losing anything in performance or aesthetics. Her cold-molded construction and new 454 MerCruiser make her strong and quick. The varnished teak and mahogany trim with an open cockpit make for beautiful and great entertaining. Trailer included.

New Engine! Getting a New Paint Job! Both included in price.
