Recmar REC663-44311-02 WATER PUMP HOUSING (REC663-44311-02) Aftermarket product	$28.05~~$31.17~~ In stock Only 4 remaining	Good	Designed as a direct 1:1 replacement with matching internal geometry and the same style of metal sleeve inserts in the mounting holes, so fit and function should be very close to OEM. Mold finish looks comparable, but it appears to be an independent reproduction made in China, so material spec consistency and long-term durability are less certain than OEM.

Peach Motors PM-WPMP-0048A Water Pump Repair Kit (No Housing) Aftermarket product	$37.00 In stock 5+ in stock	Good	Appears dimensionally interchangeable with the OEM design (matching insert-cup/plate geometry and includes key and seal), and the main metal parts are stainless. However it substitutes different gasket material and zinc-plated fasteners, and the Taiwan-made impeller rubber is more likely to have shorter life in a critical cooling pump.
