Groco BP-1 Poly Strainer Basket, 1.9 x 5.2 Inch

The Groco BP-1 Poly Strainer Basket is a replacement basket for thru hull strainer assemblies, designed to catch debris, sand, weeds, and other particulate before it can reach a boat's raw water pump or engine cooling system. Measuring 1.9 inches by 5.2 inches, this basket is sized as a drop-in replacement for strainers using this basket format, making it a straightforward maintenance part for boat owners performing routine strainer cleaning and upkeep.

Constructed of plastic, the BP-1 basket is built to resist corrosion in marine environments, unlike metal mesh baskets that can rust or degrade over time in saltwater or brackish water service. The open-top design allows for easy access when removing the basket for cleaning, so debris can be cleared out without disassembling the entire strainer housing. Keeping a spare on hand or swapping a cracked or clogged basket helps maintain steady raw water flow to onboard cooling systems.
