I just got a used mud buddy 24hp long tail. Below the u joint is a key way and I'm missing the key. I don't see it on the mud buddy parts site. Is it something I need to call for?

Would a piece of .keystock from the hardware store not suffice?

It should. I don't remember the size. You'll have to measure it, but probably 1/4"

You can get a key from a hardware store and cut off what you need. No need in ordering that!

Some 3/4 yokes have .25 keyways, some have .188 keyways. The motor will most def be 1/4 inch keyway but the prop side can be either one. Measure with a caliper or micrometer. Can get key stock for either size at a hardware store or auto parts store. Easy to find. If you need the .188 size, in fraction form it's 3/16

For .79 cents I'd buy 2 1/4" keys at the hardware store and keep a spare in the boat.

This past season near the end the key slipped out. I bought an oversize one and it held for a couple of hunts till I got it properly fixed plus some beefier set screws; good thing the shaft was good and also the bearing but I had to replace the seals. No chit, on my first LT, an 18 GD, many moons ago, I was upriver and the key slipped out so I jammed some sardine can keys in there and it held enough to get putt back the ten miles to the landing.

Thanks for the info. Got it at the hardware store.
