iboats has the best customer service I have experienced
by Norman from Smithfield, North Carolina on June 23, 2016
This is not the first product I have ordered, however the ujoints were here in less than a week, as always. On one occasion I had to send back several hundred dollars worth of parts back. With a little friendly guidence from Shelby in Iboat's customer service, who also had to help track down the merchandise, I recieved a full refund. I thought for sure I would get the "run around", instead with Shelby's help, I got a prompt, full refund. I will always see to it that I remember to use Iboats whenever I need boating supplies.

Highly Recommend
by William from Winfield, Kansas on September 17, 2015
Great quality product and super fast ship! I have been very impressed with all products I have ordered. I own two older boats, '74 Reinell and '60 Glasspar, most of the parts I have been after are stocked by iboats. Thanks again for the great customer service!

Q:
Could you tell me the dimensions of the u-joint? I would like to know the width of the cross with both caps on and the diameter of the caps. Thank You, Jeff?
A:
Sierra does not have the specs, they can only match it up by motor application.
