PM...
I got your PM about your not being able to find it at Wally World.
I'm attaching a pix to the one I bought for my GTX because the old one was rotten.
When I bought it, it came with every conceivable safety cap that was made for every ski. That was the forked type and the cap type. This red tether is strong enough to pull your safty cap off and kill the motor. I know, I got thrown from my GTX and it pulled the lanyard and killed the motor.
You'll note in the pix, I have cut off all the ones that I did not need and kept the cap for my ski. It also came with a whistle.
It may be that in your location, they aren't being carried. You might try your local Boats-r-us or West Marine.
I did a quick search, West Marine has the same, identical one I purchased from Walmart. I think I paid about $10 bucks for mine, West Marine wants $20. You can also order this online. I checked Walmarts online services and they did not have it.
If you go to West Marine, you'll pay more for that item. I don't know why, but the last time I found something online at West Marine, they charged me almost double as to what I found it for on their website. So, if you can, you might want to order it.
I'm going to attach the pix below.
