serial number with the Compatible Engine Models table above. You can also use the Mercury Serial Number Guide or consult your owner's manual to verify OEM part number 47-803630T or 47-F523065-1.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow often should I replace the water pump impeller?\u003c\/strong\u003e\u003cbr\u003e\nMost manufacturers recommend replacing the impeller every 2–3 years or 200–300 hours of operation, whichever comes first. If you frequently run in sandy or debris-laden water, inspect and replace more often.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat are the signs of a failing impeller?\u003c\/strong\u003e\u003cbr\u003e\nCommon symptoms include overheating, weak or absent telltale water stream, steam from the engine, and high-temperature alarms. If you observe any of these, shut down immediately and inspect the impeller and cooling passages.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I install this impeller without special tools?\u003c\/strong\u003e\u003cbr\u003e\nBasic hand tools (screwdrivers, wrenches, pliers) are sufficient for most installations.
