Maximize Stability & Performance: R & D Engine Mounts
Engineered for Excellence in Marine Environments, the R & D Marine Engine Mounts present a perfect blend of durability and functionality, designed to withstand the unique challenges of marine applications. These mounts offer an ideal balance, being stiff enough to absorb the propeller thrust in both forward and reverse, while remaining flexible enough to isolate drivetrain vibrations from the hull. By incorporating zinc-plated and pasivated steel parts, these mounts ensure resistance against corrosion, while the oil shield over the rubber components offers protection from petroleum products. Precision-engineered to manage the combined weight of the engine and transmission, R & D Marine mounts come preloaded to minimize engine movement, making installation straightforward with height-adjustable features and slotted mounting holes for perfect drivetrain alignment.
- Specifically designed to handle marine propulsion forces, accommodating propeller and engine thrust in both directions.
- Fail-safe design ensures longevity and reliability under demanding marine conditions.
- Height-adjustable and pre-loaded to significantly reduce engine movement.
- Slotted holes in the base facilitate precise alignment and easy installation.
- Optimal corrosion resistance with zinc-plated and pasivated steel components.
- Rubber component is shielded to protect against damage from petroleum-based products.
Choosing the Right Engine Mount
To select the appropriate engine mount:
- Determine the total weight of the engine and transmission.
- Calculate 60% of the total weight for the rear mounts (transmission side) and 40% for the front mounts, then divide by two to find the capacity needed per mount.
- Select the stud diameter and footprint based on your engine's specifications.
- Choose a mount that fits within the middle of the weight range for optimal performance.
Example calculation for a system with a combined weight of 590lbs shows the necessity for specific rear and front mounts, ensuring that each mount is selected to support the designated weight effectively, thereby optimizing the engine's stability and performance.
Why Choose R&D Marine Engine Mounts? Designed with marine propulsion in mind, these mounts not only accept but effectively manage the thrust of your engine, ensuring a stable and smooth operation. Their adjustable height and preloaded design contribute to an efficient installation process, making them a top choice for marine applications where reliability and performance are paramount.
