The Irwin Marine Laconia Ship Store is your one stop shopping solution for everything and anything related to enhancing your boating experience. The well-stocked Ship Store offers a full complement of anchors, lake charts, cleaning supplies, electrical accessories, electronics, fenders, fiberglass repair supplies, flags, navigation lights, oars, paddles, paint, bilge pumps, dock & anchor lines, sanitation supplies, sealants, trailer supplies, water sports vests, and tow tubes. For your convenience we can register your boat as well. In addition we are also the area’s best stocked Mercury/Mercruiser dealer. We realize the season is short and a well-stocked Parts Department is key to ensuring your boat is always ready to go. We also offer parts & accessories for your Sea Ray, Stingray, Yamaha jet boat, Premier, Berkshire & Crest pontoon boats, and Alumacraft fishing boats. If you’d rather rent than own, you’re in luck as we also have available the newest fleet of rental boats on the Big Lake. Need gas and a pump-out? We have you covered there as well.
