Groco BP-3 Poly Strainer Basket, Black Polyethylene Replacement Basket for Raw Water Strainers

The Groco BP-3 is a replacement poly strainer basket designed to fit inside compatible raw water strainer housings on boats, removing debris and sediment before water reaches the engine, pump, or plumbing system. The basket is molded from black polyethylene, a material chosen for its resistance to saltwater corrosion, cracking, and UV degradation, making it suitable for continuous marine service where metal baskets would eventually rust or pit. The open-top construction allows quick access for cleaning: simply lift the basket out, empty accumulated debris, rinse, and reinstall, without needing tools or gaskets. At 2.6 inches by 7.3 inches, the BP-3 is sized for standard thru-hull strainer housings that accept this basket profile, and its light weight of 0.2125 pounds means it adds negligible load to the strainer assembly. As a genuine Groco part, the BP-3 is manufactured to the same dimensions and fit as the original equipment basket it replaces, so boat owners can restore proper strainer function without modifying the housing. This basket is commonly kept as a spare or replacement item for routine strainer maintenance, since baskets can become brittle or damaged over time from sun exposure and repeated handling during cleaning.
