Professional Grade Marine Intake & Filtration
Engineered for extreme maritime environments, our 316 Stainless Steel Boat Intake Strainer represents the pinnacle of thru-hull hardware. The optimized scoop geometry ensures maximum water volume for engine cooling and livewell systems while maintaining superior hydrodynamic efficiency.
Technical Forensic Features:
- Marine-Grade AISI 316: High-molybdenum alloy providing unmatched resistance to pitting and crevice corrosion in high-salinity water.
- Precision Mirror Polish: Electropolished surface finish reduces bio-fouling and maintains a flawless aesthetic on premium yachts.
- Optimized Flow Filtration: Parallel-slotted intake design effectively filters seaweed and debris, protecting critical internal pumps.
- Universal Compatibility: Available in 9 distinct specifications from 3/8" to 3" NPT/BSP threads for versatile installation.
Ideal for yachts, speedboats, and professional fishing vessels, this thru-hull water pickup includes a precision-machined lock nut for a secure, vibration-resistant seal through any hull material.
Frequently Asked Questions
- Will this intake scoop cause significant drag or cavitation at high speeds?
- No. The hydrodynamic scoop profile is specifically engineered to minimize turbulence. Visual forensics of the slot angles show they are tapered to direct water efficiently into the shank while maintaining a laminar flow across the hull surface.
- Is 316 stainless steel really necessary, or is 304 sufficient for lake use?
- While 304 is okay for freshwater, 316 contains Molybdenum which provides critical resistance to pitting and crevice corrosion. For any vessel that might ever enter brackish or saltwater, 316 is the required standard to prevent structural failure over time.
- How do I ensure a watertight seal during installation?
- The product features a wide integrated flange and deep precision-cut threads. We recommend using a high-quality marine-grade sealant (like 3M 5200) between the hull and the flange, then securing the included 316 stainless steel nut to the internal side of the hull.
