If your motor is a 2-stroke model between 20–35 HP manufactured from 1978 onward (specific years vary by HP), this impeller should fit. Always compare the physical dimensions with your original impeller to ensure a proper match.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace my outboard impeller?\u003c\/strong\u003e\u003cbr\u003e\nA: Most manufacturers recommend replacing the water pump impeller annually or every 100–300 hours of operation, whichever comes first. If you notice reduced water flow from the tell-tale, overheating, or visible cracking\/missing blades, replace it immediately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What are the signs that my impeller is failing?\u003c\/strong\u003e\u003cbr\u003e\nA: Common symptoms include weak or no water discharge from the tell-tale hole, engine overheating, steam from the engine, or loss of power. Inspect the impeller if you experience any of these issues, as a damaged impeller can lead to serious engine damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I install this impeller myself, or do I need a professional?\u003c\/strong\u003e\u003cbr\u003e\nA: If you have basic mechanical skills and the proper tools, you can replace the impeller yourself by following your engine's service manual. However, if you're unfamiliar with lower unit removal or water pump disassembly, we recommend professional installation to avoid damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What's the difference between OEM and aftermarket impellers?\u003c\/strong\u003e\u003cbr\u003e\nA: This listing is an aftermarket replacement part (not an OEM component).
