Engine Mount w/4" Footprint - 5/8" Stud - 50-175lbs 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

Good Deal
Price is right, no stuffing to pick up, dogs love them and just throw them out after they’re dirty and your dog got the squeaker out.

Best Tennis Balls Ever
Color: Non-Squeaky - Pack of 12, Size: Medium
Admittedly, I haven't had these for very long, received on Jan 7 and today is Jan 19., 2021, only 12 days. But, we have a terrier mix who hasn't found a tennis ball she couldn't destroy given an hour or two. That is until now. Twelve Days later? She hasn't managed to destroy it at all. We have a puzzle cub that came with a ball inside it. It only took her a couple hours for the ball to rupture at the seam and another 10 minutes to completely destroy it beyond recognition. We put one of these balls in there and here we are over a week later. Not only has she not destroyed the ball but she hasn't been able to get this one out. She looks so silly trying to carry the ball inside the cube. It's hilarious. Anyway, I digress. I would totally recommend this toy for an yone who has a dog that lives to play fetch bit keeps destroying the balls. By the way, Update: Jan 31, 2021 and still going strong. No signs of damage.

Perfect tennis ball size.
Color: Non-Squeaky - Pack of 12, Size: Medium
Like most doggy balls they dont last as long as real tennis ball, but a real tennis ball can wear down her teeth. Great colors, tho in a few days they are yard colored cuz of the slobber and nature on it. Love the handy mesh bag for keeping put away until we need to get out a new one. My dog loves the no squeaky. To her squeaky is inside toy and too distracting for outdoor play. She really enjoys fetching this ball.
