Engine Mount w/4" Footprint - 5/8" Stud - 120-410lbs Capacity Per Mount
The R & D Marine Engine Mounts are designed specifically for the rigors of marine applications. The mounts are stiff enough to absorb forward and reverse propeller thrust, yet soft enough to isolate drivetrain vibrations from the hull.
To help increase the longevity of the mounts, all steel parts are zinc plated and pasivated to limit corrosion. The rubber component is covered by an oil shield to protect it from petroleum based products.
R & D Marine mounts are preloaded based on the combined engine and transmission weight to limit engine movement. To facilitate in the ease of installation the mounts are height adjusting and the mounting holes in the base of the mount are slotted to assist in alignment of the drivetrain.
How To Select (details required):
1.Define the total weight of the engine and the transmission.
2.Determine 60% of the total weight and then divide by 2 to determine the capacity of each of the rear mounts (the mounts on the tranmission side of the engine).
3.Determine 40% of the total weight and then divide by 2 to determine the capacity of each of the front mounts (the mounts opposite the tranmission side of the engine).
4.Determine the stud necessary stud diameter and footprint of the mount.
5.Choose mount most appropriately sized for the per mount weight. When possible, choose the mount nearest the middle of the weight range.
Example:
Engine weight is 480lbs., transmission weight is 110lbs., footprint is 4", stud diameter is 5/8".
Total weight is 590lbs.
590 x .6 / 2 = 177 lbs per rear mount. Mounts required are 800-010
590 x .4 / 2 = 118 lbs per rear mount. Mounts required are 800-037
