Engine Mount w/4" Footprint - 12mm Stud - 30-90lbs Capacity Per MountThe 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

Doesn’t last long
Color: DR HAZELNUT BROWN, Color: DR HAZELNUT BROWN
I love a synthetic wavy wig but this one didn’t even last the entire weekend like most do. Look very cute the first day but after that it just didn’t do what I needed it to do any

All eyes on you!
Color: DR2GDNHN, Color: DR2GDNHN
I didn't love this wig straight out of the box but after trimming the wig to frame my face and brushing out the curls (I love big hair), I absolutely fell in love with this unit. I've received so many compliments. Wig does tangle but after applying product the curl pattern returns. Will definitely purchase again!

BioYessssssss
Color: Caviar PDRN, Color: Caviar PDRN
I was honestly impressed after just one use of the Biodance Caviar PDRN Eye Patches. The difference in my under-eye area was noticeable almost immediately—my skin looked brighter, smoother, and more refreshed, like I had actually gotten a full night of sleep. It gave my eyes that well-rested, radiant look that usually takes multiple products to achieve.
What really sets these patches apart is how well they stay in place. Unlike so many other eye patches that constantly slide down and need readjusting, these adhere perfectly and stay put the entire time. I can go about my routine without worrying about them slipping off. Between the instant brightening effect and the secure fit, these have quickly become a standout in my skincare routine.

These are a winner!
Color: Caviar PDRN
These are some of the best under eye masks! I have friend about 35 different ones and these are slightly textured so they do not slip as much as a lot of the other ones! They are thin and very hydrating!!
