1991 Shamrock Mackinaw

This 1991 Shamrock Mackinaw is a 26-foot fiberglass pilothouse express built for offshore fishing. The boat features the builder's patented Keel Drive Design, known for strong performance in heavy seas and fuel efficiency. The single Ford 351 gasoline engine produces 300 horsepower and delivers a cruising speed of 16 knots with a maximum speed of 24 knots.

The pilothouse design provides shelter and visibility for the helm, with the cockpit layout typical of boats built for extended fishing runs. The hardtop structure protects the working areas, and the overall beam of 8 feet provides stability in offshore conditions.

The engine runs smoothly across all RPM ranges with good oil pressure and cool operating temperatures. The transmission shifts smoothly and quietly in both forward and reverse. The keel drive system contributes to the boat's economical operation while maintaining seaworthiness in rough water.
