26 Shamrock Stalker 1989 repowered in 2005 with a Ford 351 Efi 25th anniversary edition. Shamrock made the Stalker model to be very versatile. You can spend the day fishing or the afternoon cruising and sightseeing. The boat has a nice size cockpit and helm and a nice v-berth for lounging or storage. There is even a small head in the bow. The single engine application makes it an efficient package.
