GROCO ARG-755 Series 3/4″ Raw Water Strainer w/Non-Metallic Plastic Basket Review

Let’s Talk About GROCO ARG-755 Series 3/4″ Raw Water Strainer w/Non-Metallic Plastic Basket

The GROCO ARG-755 Series 3/4″ Raw Water Strainer w/Non-Metallic Plastic Basket is more than just a piece of plumbing; it’s the guardian of your vessel’s vital cooling systems. GROCO, a trusted name in marine hardware, designed this strainer to protect your engine from debris, ensuring smooth and reliable operation. The non-metallic basket caught my attention, promising a lighter, corrosion-resistant alternative to traditional metal strainers.

As a seasoned outdoor and tactical gear specialist, I’ve learned that reliable equipment is paramount. In the marine world, a clogged raw water intake can quickly lead to overheating and engine failure. I was searching for a robust, easily maintainable strainer to replace an aging unit on my small fishing boat, one that could handle the rigors of saltwater and occasional brackish water use.

Upon unboxing the GROCO ARG-755, I immediately noted its solid construction. The bronze head casting felt robust, and the non-metallic basket seemed surprisingly sturdy. It’s lighter than my old brass strainer, which is a plus for weight distribution in my small craft.

I considered a Perko strainer and a similarly sized Marelon unit. The GROCO won out due to its reputation for quality bronze castings and the cleverly designed non-metallic basket. I was hoping for easy cleaning and longevity, two things that often plague marine strainers.

My first impression was cautiously optimistic. The GROCO ARG-755 appeared well-built and thoughtfully designed, but the real test would be how it performed in the harsh marine environment. Time, and a fair amount of sea grime, would tell the tale.

Real-World Testing: Putting GROCO ARG-755 Series 3/4″ Raw Water Strainer w/Non-Metallic Plastic Basket to the Test

First Use Experience

I installed the GROCO ARG-755 on my 21-foot center console fishing boat, which is used primarily in saltwater bays and occasionally offshore. The installation process was straightforward, thanks to the standard 3/4″ NPT ports. The strainer replaced my old unit with minimal fuss.

I tested the strainer in various conditions, from calm, clear bay waters to choppy seas with considerable suspended sediment. The GROCO ARG-755 performed flawlessly. No noticeable reduction in water flow to the engine, even after several hours of trolling through weed-choked areas.

Using the strainer was intuitive. The one-piece molded sight glass allowed easy visual inspection of the basket’s contents. Removing and cleaning the basket was a breeze, requiring no tools. The improved drain plug made draining the strainer quick and clean.

No issues cropped up on the first outing. I was particularly impressed with the basket’s ability to capture even small particles. The sight glass remained clear, providing a good view of the basket’s interior.

Extended Use & Reliability

After six months of regular use, the GROCO ARG-755 has proven to be a reliable performer. There are no signs of corrosion or degradation, even with constant exposure to saltwater. The non-metallic basket remains in excellent condition.

Durability has been a strong point. The bronze head casting is as solid as the day I installed it. The non-metallic basket hasn’t cracked or warped, despite being subjected to numerous cleanings and temperature fluctuations.

Maintenance is minimal. A quick rinse of the basket after each trip is usually sufficient. Periodically, I’ll use a mild soap to clean the sight glass and ensure a clear view.

Compared to my previous strainer, the GROCO ARG-755 is a clear winner. It’s easier to clean, more corrosion-resistant, and provides a more reliable flow of raw water to my engine. It has exceeded my expectations for a marine strainer.
