A stern thruster paired with a bow thruster gives you true sideways control across the full length of the boat, letting you move parallel to a dock rather than pivoting around one end. The T-shaped tunnel design is specifically engineered for transom mounting on flat-transom powerboats, directing thrust left and right efficiently. Available to match Lewmar thrusters from 140TT to 300TT, so your bow and stern thrusters can share the same control architecture.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eUse\u003c\/strong\u003e\u003cbr\u003eDesigned for mounting on flat powerboat transoms. The 185mm tunnel diameter matches the 185TT thruster series exactly — the thruster unit is sold separately and must be ordered alongside this kit. Confirm your transom's thickness and layout against Lewmar's installation requirements before ordering.\u003c\/p\u003e","brand":"Lewmar","offers":[{"title":"Default Title","offer_id":45216450511030,"sku":"LEW\/589310","price":1609.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/6584\/6966\/files\/LEW589310_001.jpg?v=1783545960","url":"https:\/\/ampedupmarine.com\/products\/lewmar-589310","provider":"Amped Up Marine","version":"1.0","type":"link"}
