Extreme Max Clean Rig Spacer 3 11/16″ Diameter Review

Everything You Need to Know About the Extreme Max Clean Rig Spacer 3 11/16″ Diameter

For anyone dealing with marine electronics, the quest for a tidy and professional installation is often a constant battle. My own experience on the water, whether fishing or simply cruising, has taught me the value of a well-organized rig. Wires can become a tangled mess, snagging on gear and detracting from the overall aesthetic and functionality of the boat. This is precisely the problem that the Extreme Max Clean Rig Spacer 3 11/16″ Diameter aims to solve. I stumbled upon this particular spacer while troubleshooting a particularly unruly wiring loom for a new depth finder I was installing on my center console.

Upon first glance, the spacer presents itself as a simple, yet effective, piece of engineering. It feels robust in the hand, not like a flimsy piece of plastic that might crack under stress. The material has a pleasing heft, suggesting it can withstand the rigors of a marine environment. I considered some generic rubber grommets and even tried fabricating a solution from scrap plastic, but none offered the precise fit and clean look this specialized part promises. My initial impression is one of quiet satisfaction, a feeling that a simple, well-designed solution to a common problem has finally arrived.

Real-World Testing: Putting Extreme Max Clean Rig Spacer 3 11/16″ Diameter to the Test

First Use Experience

My primary testing ground for this spacer was my own vessel, a 22-foot center console that sees regular use on saltwater. The specific scenario involved mounting a new 2.25″ RAM ball mount for a fish finder, directly onto a slightly uneven fiberglass console surface. This surface isn’t perfectly flat, and a direct mount can sometimes lead to stress on the base or an unsightly gap. The spacer’s job was to bridge that gap and provide a uniform surface for the RAM mount to attach securely.

Installation was remarkably straightforward. After positioning the RAM ball mount and the spacer, I simply marked my drill points through the pre-drilled holes in the spacer. I used #10 stainless steel screws, as recommended by Extreme Max, and the process was as simple as drilling pilot holes and driving the screws home. The spacer compressed slightly, conforming to the subtle contours of the console, and provided a perfectly flat and stable base for the RAM mount. There were no initial issues or surprises; it performed exactly as advertised, offering a clean, professional-looking finish that immediately improved the overall appearance of the helm.

Extended Use & Reliability

Several months have now passed since I installed the Extreme Max Clean Rig Spacer 3 11/16″ Diameter, and it has held up exceptionally well to the harsh marine environment. The boat is frequently exposed to salt spray, sun, and occasional heavy rain, yet the spacer shows no signs of degradation. There are no cracks, no discoloration, and it remains perfectly firm, with no loosening of the mount.

Cleaning is as simple as wiping it down with a damp cloth or a mild boat soap when I wash the boat. It doesn’t trap dirt or grime, which is a significant advantage over some other mounting solutions. Compared to previous experiences with rubber washers that tend to harden and crack over time, or just using a flat washer and accepting a small gap, this dedicated spacer proves its worth. Its specific design for this diameter base makes it superior to trying to adapt a generic part.

Breaking Down the Features of Extreme Max Clean Rig Spacer 3 11/16″ Diameter

Specifications

This spacer is designed with a 3 11/16″ (3.68″) diameter, which is a key specification for compatibility. It’s specifically engineered to accommodate 2.25″ RAM Ball Mounts, a very common standard in marine electronics installations. The product description highlights that it is pre-drilled to fit standard mounting patterns, which significantly simplifies installation. The material appears to be a durable, marine-grade plastic or composite, designed to withstand UV exposure and saltwater without deteriorating.

The 3 11/16″ diameter is crucial because it creates a larger, more stable footprint than the base of the RAM mount itself, distributing pressure over a wider area. This is particularly beneficial when mounting on softer surfaces like fiberglass or some plastics, preventing distortion or damage. The pre-drilled holes ensure that alignment is easy, eliminating the guesswork involved in centering and marking a mount on a curved or irregular surface. For those with smaller mounting bases, Extreme Max offers a different size, indicating thoughtful product line development.

Performance & Functionality

The primary function of the Extreme Max Clean Rig Spacer 3 11/16″ Diameter is to provide a clean, professional, and stable mounting surface for marine electronics. In this regard, it excels. It effectively eliminates the unsightly gap that can occur when mounting a base onto a non-flat surface. Furthermore, by providing a solid, uniform interface, it enhances the stability of the mounted device, reducing potential vibration and wear on the hardware.

Its biggest strength lies in its simplicity and effectiveness. It does exactly what it’s designed to do, making the installation process cleaner and the final result more polished. One minor point for consideration, though not a flaw, is that it doesn’t come with mounting hardware. While this is clearly stated and understandable given the variety of mounting surfaces, it means users need to source appropriate #10 stainless steel hardware separately, adding a small step to the process.

Design & Ergonomics

The design of this spacer is functional and straightforward. Its circular shape and precise diameter are its defining characteristics. The material feels substantial, suggesting it won’t easily crack or warp.

The pre-drilled holes are a significant ergonomic advantage, guiding the user for a quick and accurate installation. There’s no complex setup or learning curve; it’s an intuitive component that integrates seamlessly into the mounting process. Its simple design means there are no fiddly parts or controls to worry about, just a solid piece that enhances the mounting system.

Durability & Maintenance

Given its intended use in a marine environment, durability is paramount, and this spacer appears to be built for the long haul. The material resists the corrosive effects of saltwater and the damaging rays of the sun.

Maintenance is practically non-existent, which is ideal for any boater. A simple wipe-down during regular boat cleaning is all that’s required to keep it looking new. There are no obvious weak points or potential failure mechanisms, making it a reliable component for any marine installation.

Accessories and Customization Options

The primary “accessory” for this spacer is the mounting hardware, which needs to be purchased separately. Extreme Max recommends #10 stainless steel hardware, and I would echo that recommendation for marine applications. The spacer itself is designed for a specific purpose and doesn’t offer broad customization beyond its core function.

Its main compatibility is with 2.25″ RAM Ball Mounts, but the description also notes it works with “any other marine electronics with a 3-11/16″ (3.68″) mounting base,” suggesting potential for other accessories beyond RAM. However, the key is ensuring the accessory has a base diameter that matches or is smaller than the spacer’s outer diameter.

Pros and Cons of Extreme Max Clean Rig Spacer 3 11/16″ Diameter

Who Should Buy Extreme Max Clean Rig Spacer 3 11/16″ Diameter?

This spacer is an excellent choice for boat owners and marine enthusiasts who are installing or upgrading electronic devices like GPS units, depth finders, fish finders, or communication equipment that utilize a 2.25″ RAM ball mount or a similar 3-11/16″ diameter base. It’s perfect for anyone who values a tidy, professional-looking helm and wants to ensure their electronics are mounted securely and reliably. DIYers and even professional marine installers will appreciate the ease of use and the polished result it delivers.

Those who might want to skip this product are individuals who are not mounting any accessories with a 3-11/16″ base or 2.25″ RAM ball, or those who are mounting directly onto a perfectly flat and suitable surface where a spacer isn’t needed. If you are working on a very tight budget and willing to accept a less professional finish or a potentially less stable mount, you could try to improvise, but it’s unlikely to yield the same clean result. For those who do purchase it, ensuring you have the appropriate #10 stainless steel mounting hardware is key.
