The Real Deal Behind the GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket
My onboard raw water system had been giving me persistent grief. A recurring issue with debris clogging the intake line, despite the rudimentary strainer I’d been using, meant unscheduled dives and frustrating downtime. I needed a robust, reliable solution that could handle the varied detritus nature throws at a marine engine’s intake. Enter the GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket. This unit from GROCO promised a significant upgrade with its durable construction and thoughtful design features, specifically the non-metallic basket which was a key draw for me. I’d been looking at a few other brands, but the reputation of GROCO and the specific features of this model, like the ability to easily service the basket without tools, tipped the scales. The initial impression upon unboxing was one of solid engineering – the cast bronze head felt substantial, and the plastic components, while not metal, had a satisfying heft and precision fit. There was a definite sense of relief; this felt like a component built to last.
Real-World Testing: Putting GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket to the Test
First Use Experience
My first real test for this strainer was during a routine haul-out and engine service. I installed it directly into my main raw water intake line, replacing the old, smaller unit. The 2-inch NPT threaded ports were straightforward to connect, and the initial setup was surprisingly intuitive, even for someone not intimately familiar with plumbing systems. The real test came when we fired up the engines and began circulating water. I specifically kept an eye on the sight glass, anticipating it might immediately cloud with fine silt from the bottom cleaning. It remained remarkably clear, indicating good initial filtration. The ease with which I could later remove the non-metallic cap to inspect the basket was a revelation compared to my previous, more fiddly setup.
Extended Use & Reliability
Months later, and after countless hours of engine operation in a variety of conditions – from calm bays to choppy seas filled with weed and small shells – this strainer has held up exceptionally well. I’ve only had to clean the non-metallic plastic basket a handful of times, which is a testament to its efficiency and the robust nature of the system. The o-ring seal on all joining surfaces has proven to be completely leak-free, even under the significant pressure fluctuations of a working marine engine. Compared to the flimsy plastic strainers I’ve encountered on less critical systems, this GROCO unit feels like it’s built for a commercial application, not just a recreational vessel. Maintenance is a breeze; a quick rinse of the basket is all that’s usually required, and it slides back into place effortlessly.
Breaking Down the Features of GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket
Specifications
The GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket is a substantial piece of equipment, featuring a robust C84400 bronze head casting that speaks to its marine-grade durability. The headline feature is undoubtedly the non-metallic plastic basket, which is designed to be resistant to corrosion and chemical degradation often found in raw water environments. This basket is paired with an o-ring seal that ensures a watertight connection with the strainer body. The unit boasts 2-inch NPT or BSPP threaded ports, offering broad compatibility with standard plumbing. A unique aspect is the one-piece molded sight glass, which eliminates the need for tie rods and gaskets that can be failure points. The cap, neck, and drain plug are also constructed from non-metallic materials for enhanced longevity and ease of use, especially the non-metallic cap which allows for clear internal viewing. This model is UL Listed 255-D, a certification that underscores its quality and safety.
Performance & Functionality
In practice, the GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket performs its primary function with exceptional efficacy. It effectively captures a wide range of debris, from fine sand and silt to larger fragments of seaweed and shells, preventing them from reaching sensitive engine components like impellers and heat exchangers. The non-metallic basket’s design promotes good flow rates, and I haven’t experienced any noticeable reduction in water intake pressure. Its ability to capture even small particulates means I’m seeing cleaner water exiting the system, which is beneficial for heat transfer. The improved drain plug is also a welcome addition, making draining for maintenance quick and mess-free.
Design & Ergonomics
The design of this raw water strainer is clearly driven by function and longevity. The cast bronze head is a significant advantage, providing a strong mounting point and resistance to corrosion in a saltwater environment. Its heft instills confidence in its structural integrity. The non-metallic cap is a clever touch; it not only resists marine growth but also provides a surprisingly clear view of the basket’s contents, allowing for quick visual inspections. The mounting system is designed for easy removal without tools, which is a significant ergonomic win when routine maintenance is required. Everything about its construction screams “built to endure.”
Durability & Maintenance
Based on my extended use, the durability of the GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket is excellent. The bronze head shows no signs of pitting or corrosion, and the plastic components, including the basket and cap, remain free from cracks or deformation despite constant exposure to water and temperature variations. Maintenance is straightforward; the non-metallic basket can be easily removed by unscrewing the cap, rinsed clean, and reinstalled. The improved drain plug makes emptying the unit simple. I have noticed no significant wear and tear that would suggest a premature failure.
Accessories and Customization Options
The GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket primarily comes as a complete, integrated unit. The key “customization” or variation comes in the form of available filter basket options: #304 SS (Standard) Monel & Non-Metallic. My review focuses on the non-metallic plastic basket, which I find ideal for general use due to its corrosion resistance and light weight. The unit also features bonding connections on both sides, which is an important safety and system integrity feature in marine applications. While there aren’t typical “accessories” in the consumer product sense, the choice of basket material is the main point of customization.

Who Should Buy GROCO ARG-2000 Series 2″ Raw Water Strainer w/Non-Metallic Plastic Basket?
This raw water strainer is an exceptional choice for marine vessel owners operating in waters with significant debris, such as coastal areas, rivers, or lakes prone to weed and shell growth. It’s ideal for anyone looking for a long-term, low-maintenance solution for their engine’s raw water intake. Boat owners who frequently service their own engines and value ease of access for maintenance will greatly appreciate the tool-less removal system.
