irregular cover, manufactured before March 2004. Do not use on pumps with a round cover and O-ring seal; those require impeller kit 48500. Before installation, shut off the engine and close the seacock. Lubricate the new impeller and the inside of the pump housing with a suitable marine lubricant to prevent damage during initial startup.\u003c\/p\u003e\n\n\u003ch2\u003eTroubleshooting \u0026amp; FAQ\u003c\/h2\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eHow do I know if this impeller fits my generator?\u003c\/summary\u003e\n  \u003cp\u003eVerify your generator is listed in the compatibility table. Most importantly, check that your sea water pump is model 33636 and has an irregular-shaped cover held on by screws. If your pump cover is round and uses an O-ring, this part will not fit.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat is the difference between this kit and one for newer models?\u003c\/summary\u003e\n  \u003cp\u003eThis kit is for pre-March 2004 pumps with an \"irregular\" cover. Newer Westerbeke pumps often use a round cover with an O-ring, which requires a different impeller and seal (like kit 48500). The physical dimensions and included gasket are specific to the older pump design.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eHow often should I replace my water pump impeller?\u003c\/summary\u003e\n  \u003cp\u003eAs a general rule, impellers should be inspected annually and replaced every 1-2 years or every 200-300 hours of operation, whichever comes first.

A complete failure can cause rapid overheating and serious engine damage.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eIs the included gasket necessary?\u003c\/summary\u003e\n  \u003cp\u003eYes. The gasket is critical for creating a watertight seal between the pump housing and the irregular cover plate.

Additionally, check the dimensions (51mm diameter, 22mm width) and drive type (Pin Drive) against your old part.
