At the 250TT size, the stern thruster is handling serious thrust loads — the GRP construction is sized and engineered to Lewmar's specifications for this power level, with 6-point M10 fixing pattern for a secure, high-load installation.\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.
