R & D Marine Engine Mount Kit Review

Let’s Dive into R & D Marine Engine Mount Kit

The R & D Marine Engine Mount Kit is designed to dampen engine vibrations in small Yanmar diesel engines, a constant source of noise and potential wear in any vessel. Manufactured by R & D Marine, this kit is specifically tailored for the Yanmar 1GM, 2GM, 3GM, 3YM, 3HM, and 3JH series engines, offering a solution for boat owners experiencing excessive engine movement or vibration.

I was troubleshooting excessive vibration on my 3GM30 Yanmar engine, and it was shaking the whole boat! I tried tightening everything and even isolating parts that could be loose, but it turns out the old engine mounts were worn. I needed a reliable, durable replacement that would properly isolate the engine and reduce that annoying and potentially damaging vibration.

Unboxing the R & D Marine Engine Mount Kit, my first impression was that these were serious, well-built pieces of equipment. The zinc-plated steel and oil shields gave an immediate sense of robustness. The adjustability of the mounts and slotted base holes showed that R & D Marine really thought about installation challenges.

Several other engine mount kits exist on the market, but I selected this kit because of R & D Marine’s reputation for quality and their specific engineering for Yanmar engines. Many generic mounts lack the specific preload and vibration dampening characteristics required for marine applications. This product offered a tailored solution, and it’s worth paying more for something that is going to do the job correctly and last.

My initial reaction was excitement. I’ve been through a few cheap engine parts over the years and learnt the hard way. It’s worth paying a bit more up front to avoid having to replace parts later down the line. If these mounts performed as described, they promised a smoother, quieter, and more enjoyable boating experience.

Real-World Testing: Putting R & D Marine Engine Mount Kit to the Test

First Use Experience

I installed the R & D Marine Engine Mount Kit on my sailboat in its slip. The installation process, while straightforward with basic tools, took a few hours because of the confined engine compartment. The slotted holes and height adjustability were immediately helpful in aligning the engine with the propeller shaft.

The difference was immediately noticeable once the engine was started. The excessive shaking was gone, and the whole boat felt calmer. Even at higher RPMs there was a significant reduction in vibration compared to the old mounts.

Installation required some tweaking to the height adjustments, so I’d recommend a laser level and a good eye. However, the improved experience made the initial effort well worth it.

Extended Use & Reliability

After several months of regular use, including some rough weather, the R & D Marine Engine Mount Kit continues to perform flawlessly. There are no signs of increased vibration or wear. The engine sits securely and transmits minimal vibrations to the hull.

The zinc plating shows no signs of corrosion, despite the harsh marine environment. I have inspected the rubber components and the oil shields are protecting them well, so they’re in good condition so far.

This R & D Marine kit has far exceeded my expectations. My previous experiences with aftermarket engine mounts were less positive, with some failing within a year. The R & D Marine Engine Mount Kit has transformed the boating experience and instilled confidence in the longevity of my engine installation.

Breaking Down the Features of R & D Marine Engine Mount Kit

Specifications

• Suitable for Yanmar Engines: Designed specifically for the Yanmar 1GM, 2GM, 3GM, 3YM, 3HM, and 3JH series engines. This ensures a proper fit and optimal performance.
• Designed for Marine Use: Built to withstand the unique rigors of marine environments, including constant exposure to moisture and saltwater. This is critical for long-term reliability.
• Stiff but Dampening: The mounts strike a balance between stiffness for thrust absorption and softness for vibration isolation. This dual functionality is crucial for comfortable and efficient operation.
• Zinc-Plated Steel: All steel parts are zinc plated and passivated for corrosion resistance. This extends the lifespan of the mounts in a marine environment.
• Oil Shields: The rubber component is protected by an oil shield to prevent degradation from petroleum-based products. This protects the dampening components.
• Preloaded Design: Mounts are preloaded based on engine and transmission weight to limit engine movement. This reduces stress and wear on connected components.
• Height Adjusting: The mounts are height adjustable, simplifying installation and alignment. This addresses a key challenge in marine engine installations.
• Slotted Mounting Holes: Slotted holes in the base of the mount assist in aligning the drivetrain. This enhances ease of installation and reduces potential alignment issues.
• Fail-Safe Design: Offers a fail-safe design. This adds an extra layer of protection and safety.
• Mount Types to Fit All Applications: R & D Marine Mounts are height adjustable and have mount types to fit all applications. This ensures versatility for different engine setups.

Performance & Functionality

The R & D Marine Engine Mount Kit significantly reduces engine vibration, leading to a quieter and more comfortable ride. It also protects the hull from engine-induced stress. The reduction in vibration translates to less noise and improved overall comfort on board, especially on longer journeys.

The mounts are robust and reliable. They keep the engine securely in place even under heavy loads and in rough sea conditions. I have full confidence in their ability to perform consistently.

This kit not only met but exceeded my expectations. The improved performance and peace of mind regarding engine stability make this a worthwhile investment.
