GROCO 1.5-Inch Bronze Clam Shell Hull Strainer

The GROCO SC-1500-L hull strainer protects a thru-hull intake from larger debris before that material reaches the plumbing inside the boat. Its clam-shell exterior body covers the intake opening while still allowing water to reach the thru-hull. This configuration is intended for standard intake flow, making it suitable for intake systems matched to that flow behavior. The hinged door gives the owner a practical way to reach the underlying fitting when inspection or cleaning is needed.

GROCO casts the SC-1500-L body and door from marine bronze and uses cast filter slots with pressure-relief holes to screen the incoming water. The accessible door also makes it easier to inspect the intake face during haul-out maintenance. The strainer is shaped to sit on the outside of the hull, so the mounting surface and orientation should be planned before holes are drilled. By keeping sticks, weeds, and larger debris away from the thru-hull entrance, the strainer can reduce the amount of material that reaches downstream baskets and pumps.

• Hinged door for service access
• Clam-shell hull-side intake protection
• Bronze body and access section for marine use
• Cast filter slots with pressure-relief holes

Position the SC-1500-L so it fully covers the intended thru-hull without interfering with nearby fittings or hull features. Use marine bedding and fasteners appropriate to the hull construction, and make sure the access section can still open after installation. During haul-outs, clean marine growth and packed debris from the openings so the connected intake can receive normal flow.
