Yamaha outboard?\u003c\/strong\u003e\u003cbr\u003e\nA: Check your engine model and horsepower against the compatibility table above. The primary application is for Yamaha E40G 40-55HP models, but it also fits various 2-30HP 2-stroke and 2-25HP 4-stroke engines. Verify your original part number (663-43118-01 or 6F5-43116-00) to ensure proper fitment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What are the signs that my transom clamp needs replacement?\u003c\/strong\u003e\u003cbr\u003e\nA: Common indicators include difficulty tightening or loosening the clamp screw, visible cracks or corrosion on the handle or bracket, excessive play or wobble in the motor mounting, or stripped threads on the clamp screw.
