At the 300TT size — the largest in Lewmar's electric TT lineup at up to 15kW — the stern thruster is handling the most demanding thrust loads in the range. The GRP construction is engineered to Lewmar's specifications for this power level, sized and reinforced for a 300mm tunnel diameter.\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 300mm tunnel diameter matches the 300TT 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. Professional installation strongly recommended at this size.\u003c\/p\u003e","brand":"Lewmar","offers":[{"title":"Default Title","offer_id":45216451952822,"sku":"LEW\/589710","price":2129.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/6584\/6966\/files\/LEW589710_001.jpg?v=1783546763","url":"https:\/\/ampedupmarine.com\/es\/products\/lewmar-589710","provider":"Amped Up Marine","version":"1.0","type":"link"}
