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

Don't buy they don't work only 3 hours that's it
Size: 1 Count (Pack of 12)
These are cheap and when I went to take it off it broke they only last three to four hours that's it then the scent is gone. I have bought these many a times from a different seller and they last me a long time matter of fact I got them at the Dollar tree

My Go-To Cotton Rounds — Don’t Fall Apart & No Fuzz
Color: Ultra Soft, Size: 100 Count (Pack of 3)
These are my favorite cotton rounds, and I’ve tried everything from dollar store versions to higher-end “eco” brands. I keep coming back to these. They stay intact and do not separate, even when fully saturated. I use them for micellar water, toner, and nail polish remover, and they hold up well with all three. No fuzz left behind, no pilling, and no pieces sticking to my face. The thickness is just right — not too thin, not overly bulky. They’re soft but durable. I also like that one side has a slight texture. It’s not harsh or labeled as “exfoliating,” but it does have a subtle grip that helps with product application without irritating the skin barrier. Compared to cheaper brands that fall apart and more expensive ones that don’t perform any better, these strike the perfect balance of quality and value. Definitely a repeat purchase for me. TL;DR: Soft, durable, no fuzz, and don’t fall apart. Perfect thickness for toner, micellar water, and nail polish remover. My consistent repurchase.

Good Quality Cotton Rounds
Color: Ultra Soft, Size: 100 Count (Pack of 3)
I recently purchased these cotton rounds, and I couldn’t be happier with them! They are soft, durable, and incredibly gentle, making them perfect for my daily skin care routine. They don’t leave behind any lint, and they hold up well when applying toner or removing makeup. One unexpected bonus is how great they are for my cat with skin allergies. I use the rounds to gently clean around sensitive areas, and the soft texture ensures I don’t irritate her skin. Another huge plus is the value. The set comes with a generous amount of rounds for the price, which makes it both practical and economical. For anyone looking for versatile, skin-friendly cotton rounds that work for both personal care and gentle pet care, this set is an excellent buy!
