Engine Mount w/6.85" Footprint - 5/8" Stud - 80-230lbs Capacity Per Mount** Designed as a front mount for the Yanmar 4JH series engine
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

It is what I was looking for
Size: 10-13, Color: Black Lattice
The product is use for a at home slipper so that I don't need to wear shoes. I can relate my feet with a soft support on the bottom of my feet.

What I've been looking for
Size: Large (Pack of 1)
Just got my Nero Ball. Only used it once, but really like it. I've tried other "ball on a string" type toys, with unsatisfactory results. I'll be using it as a training reward, and my boy, who is a pretty ferocious tugger, is going to learn 2 new things with this ball. 1st, to target the ball instead of the rope, and 2nd, that it's for a little gentle tugging instead of the full throttle stuff he does otherwise. After our 1st session with the Nero Ball, he's picking up on the new rules quickly. We'll see how it does long term, but I think this is one I'll stay with.
*UPDATE* Been using my Nero Ball for a month now. I'm tempted to call it the 'Hero Ball' because it's just that terrific!! For me, the key has been putting in the time to allow both myself & my dog to develop the skill to use this tool smoothly. May sound strange, but using a toy as a training reward requires practice, and each different toy configuration requires different handling. It's time well spent - we're both having a lot of fun!
Kudos to the designer of this ball. Every detail has been carefully considered, from the length & material of the rope (just the right length that the dog won't step on it; material is easy on the hand while still being tough enough to withstand a few toothy grabs; the loop is the perfect size to grab for a little tug or to pass the ball through to slip-knot it onto a belt loop). The ball is also just right. The knobs make it non-slip, the rubber eliminates tennis ball fuzz concerns, and being semi-hard and hollow makes it slightly compress-able, which makes it a higher value reward than a solid ball that can't be compressed.
While this ball will not work for every application or for every dog, if you carefully read & understand the information provided and don't expect it to work outside those parameters, you will be pleasantly surprised by a very well designed, well constructed tool that you can use to enhance your training or play sessions with your dog.

Nice toy
Size: Large (Pack of 1)
This product is generally durable and easy to throw. However, the original rope knot came undone after just four throws, per my wife. Unfortunately, my knot-tying skills are limited to fishing knots and slip knots, which is on me. While I can't give a perfect score, I believe it deserves a 4.5 out of 5 stars due to the knot issue. A simple solution would be to apply heat shrink tubing over the knot and heat it to secure it, which would enhance its reliability and potentially elevate the rating to a perfect five stars.

Our German Shepherd loves it!
Size: Large (Pack of 1)
Order arrived promptly and in good condition. Our GSD barely let us get it out of the package before wanting to play with it. Works great as training reward and for fetch games. Been using it for three weeks, and it is holding up well.
