I have been following this website for quite a while but never posted till now. I have a mad mud motor with a 6.5 hp Honda clone and Im wanting to buy the 13 hp harbor freight motor and hook it up but here's the problem the shaft sizes are different. So has anyone ever heard of either a yoke that connects a 1 in crank shaft u joint to a 3/4 in u joint ?? I want to keep my 3/4 in drive shaft and frame the same and I have been stressing out about this as you can tell I'm posting this past midnight and I have to work Tommorow. Any help is greatly appreciated, I hope someone knows more about this than I do.

why you stressin? lol

There are plenty of them out there - I use one on my 20hp GDLT - i'll try and get the serial numbers off them tonight so you can google them.

Go to driveshaftparts.com they have the kit for 25 bucks you order two yokes and a u-joint. I have a 16 hp that has the 1 inch shaft and my driveshaft is 3/4

Thanks I appreciate it . I have been searching for a while now. How is yours setup do you have the 1 in joint that connects to the 3/4 yoke or do you have a yoke that has both sizes?

Thanks trapper is there anyway you could give me a URL im having trouble finding it.

dude i got the set from driveshaftparts.com sitting on my work bench 1" yoke x 1/4 keyed, u joint and 3/4 yoke x 3/16 keyed. i assembled it and never used it. 1500 series i believe. you want? make me an offer. whats your driveshaft keyed?

Ya let me measure it up first but I'm pretty sure they will work. I will pm you Tommorow and let you know for sure. I really appreciate it!
