Peach Motors PM-WPMP-0009A Water Pump Repair Kit (No Plastic Housing) Aftermarket product	$67.45 In stock 5+ in stock	Good	China-made rebuild kit that appears functionally compatible (including a 6-blade impeller marked “6H4”) but is supplied in generic/bulk packaging with less component traceability than OEM. It explicitly excludes the plastic housing, and the long-term durability of the impeller rubber and sealing parts is less proven for a high-consequence cooling component.

Peach Motors PM-WPMP-0042A Water Pump Repair Kit (With Plastic Housing) Aftermarket product	$82.05 In stock Only 4 remaining	Good	Taiwan-made kit includes a new plastic pump housing along with the main stainless wear components, which can help if the original housing is worn or scored. Hardware is standard zinc-plated flange bolts rather than marine-grade stainless, and aftermarket impeller rubber quality is still a key unknown compared with OEM for preventing overheat-related failures.

Shopping experience: Found the product, the only online store that had it. I live in Canada, and everything is in USD and ships from US, so perhaps make it just a bit more obvious on the website that the prices are USD, and duties and taxes will be applied at delivery (although it does say that in the shipping policy section). Other than that, definitely recommend. Repair difficulty: Easy Repair time: Less than 30 mins
