First Use Experience

My initial encounter with the Sierra International Shims 0.006in occurred on my workbench in the garage, a space where precision meets practicality. I was tasked with fine-tuning the clearances on a Johnson 70 HP outboard engine, a project that demanded absolute accuracy. The environment was controlled, with good lighting and all necessary tools at hand, which is ideal for this type of delicate work.

The shims were straightforward to use; they are essentially thin, precise washers designed to be stacked or used individually to achieve the desired gap. There was no steep learning curve; their function is inherently simple, and they integrated seamlessly into the assembly process. My first test involved fitting them to establish the correct backlash on a gear assembly, a task that requires a very specific feel and measurement.

During this initial fitting, I noticed how consistently manufactured each shim was. They slid into place without any discernible drag, and importantly, they maintained their shape and integrity when subjected to the light pressure of assembly. There were no unexpected issues; they performed exactly as their specifications suggested they would, which, in my line of work, is a significant part of a successful product experience.

Extended Use & Reliability

After successfully completing the engine rebuild, the Johnson outboard was put through its paces on the water. This involved several hours of operation in various conditions, from calm lake cruising to more demanding trolling and higher-speed runs. The engine performed admirably, with the previously addressed clearances holding true throughout the testing period.

The true test of reliability for these small components comes with time and repeated stress. Weeks turned into a couple of months, and the outboard continued to be used periodically, experiencing both freshwater and occasional saltwater exposure. The shims, being internal to the engine’s critical components, have shown absolutely no signs of degradation. There have been no leaks, no deformation, and no performance drop that could be attributed to their function.

Maintenance and care for these shims are essentially non-existent once they are properly installed. They are protected within the engine housing, shielded from direct environmental contaminants. Cleaning is only relevant if they are being reused or handled during another disassembly, in which case a simple wipe-down is sufficient. Compared to previous experiences with generic metal shim stock, which can sometimes be prone to corrosion or easily bent out of shape, these Sierra International units feel considerably more robust and purpose-built. They definitely stand up well against more budget-oriented alternatives.

Specifications

The Sierra International Shims 0.006in are precisely engineered for critical adjustments within specific outboard engine applications. Each shim boasts a 1.530″ I.D. (Inner Diameter), which is the precise measurement of the hole in the center. This specification ensures it fits snugly around the shaft or component it’s intended to interface with, preventing unwanted movement or misalignment.

The crucial functional dimension is their thickness: 0.006″. This wafer-thin profile allows for incredibly fine-tuning of clearances, which is essential in high-performance or precision mechanical systems. The fact that they are sold in a two-shim per package format is practical, offering a spare or the ability to stack them if a slightly thicker adjustment is needed, though that would depend on the specific application.

Their interchangeability with Johnson/Evinrude Outboard part number 320169 is a significant advantage, providing a direct, reliable aftermarket solution for common repair needs. This interchangeability ensures that mechanics and DIY enthusiasts can confidently source replacements that meet original equipment manufacturer (OEM) standards.

This meets and arguably exceeds expectations for a component of this nature, especially considering its relatively low price point.

A potential minor weakness, depending on the user’s perspective, is the limited number of shims per package. For certain complex repairs that might require multiple shims of the same thickness, or for those who tend to be overly cautious and like to have extras, the inclusion of only two might feel a bit restrictive. However, for the vast majority of intended applications, two is usually sufficient.

Design & Ergonomics

The design of these shims is fundamentally simple, as befits their purpose, but that simplicity belies a careful execution. They are crafted from what appears to be a durable, non-corrosive metal alloy, likely stainless steel or a similar material chosen for its strength and resistance to wear and chemical attack. The finish is smooth and uniform, with no sharp edges or burrs that could cause issues during installation or operation.

In terms of ergonomics, shims are not designed for hand-held manipulation in the way a tool might be. Their usability comes from their perfect fit and ease of insertion. The 1.530″ I.D. ensures they slip over the intended shaft or stud without force, and their thin profile means they don’t interfere with surrounding components. The design is purely functional, prioritizing accuracy and reliability above all else.

Practical design details include the uniform flatness and the exact 0.006″ thickness. These are not features you interact with directly, but they are the bedrock of the product’s effectiveness. The crispness of the stamped dimensions on the packaging, clearly indicating the part number and specifications, is also a helpful touch.

Given their intended use within the protected confines of an outboard engine, the Sierra International Shims 0.006in are designed for excellent durability and effectively indefinite lifespan under normal operating conditions. They are not subject to friction, impact, or environmental exposure once correctly installed. barring a catastrophic engine failure or an instance of extreme corrosion from highly aggressive chemicals, these shims will likely outlast the engine itself.

Maintenance is virtually nonexistent. If an engine is disassembled for further work, these shims can be cleaned with a degreaser and a soft cloth if necessary and then reinstalled, assuming they are still in perfect condition. There are no specific maintenance tips beyond careful handling during disassembly and reassembly to avoid scratching or deforming them.

Potential concerns are minimal. The most likely failure point would be accidental damage during installation or removal, such as dropping them on a hard surface where they could potentially bend slightly, or attempting to force them into a situation where they don’t fit correctly. However, the material seems robust enough to withstand typical workshop handling.

Accessories and Customization Options

The Sierra International Shims 0.006in are designed as standalone replacement parts, and as such, they do not typically come with accessories. They are not a product that lends itself to customization in the traditional sense; their value lies in their precisely manufactured, fixed dimensions.

However, the product itself offers a form of “customization” through its ability to be used in conjunction with other shims of the same or different thicknesses (if the application allows) to achieve a very specific final clearance. The fact that they are interchangeable with OEM part numbers means they can be integrated into any repair or modification that originally called for the Johnson/Evinrude part 320169. While there aren’t aftermarket performance enhancements for a simple shim, their availability in precise increments is the key to achieving optimal engine performance.
