It replaces 0377230, 377230, 0777213, 777213, 0777821 and 777821 and crosses to Sierra 18-3083, GLM 89660, CEF 500352 and Mallory 9-45209, and it is one impeller with a drive key.\u003c\/p\u003e\n\n\u003cp\u003eThe impeller measures 69.85 mm outside diameter, 21.84 mm high and 16 mm at the hub with a keyway, and those three numbers decide whether it fits. A pump that takes this impeller will not take a 2.75 in impeller from another family, and a keyed shaft is not interchangeable with a splined one.\u003c\/p\u003e\n\n\u003cp\u003eOn these older motors the impeller is the part that ends the season: neoprene takes a set when it sits dry over winter, and the vanes that were straight in October are curled and cracked by May. Run a motor with a set impeller and the first thing you notice is a weak tell tale, then a hot powerhead.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable
