DOES NOT FIT!!!
by Jennifer from Gilbert, Arizona on April 25, 2012
I ordered this to put into the Volvo Penta Engine that I have on my boat... The people at iboats AND the people at Sierra (the manufacturers of this part) BOTH promised me "without a shadow of a doubt" that it would work to replace the old U-Joint's in my engine. THEY DO NOT FIT!!! We ended up having to eat the money we spent on these and just order an entirely new shaft for my engine from Volvo themselves. DO NOT BELIEVE ANYONE WHEN THEY SAY THAT THESE WILL CROSS REFERENCE WITH YOUR VOLVO MOTOR!!!

Missing seal
by Michael from Minnetrista, Minnesota on February 23, 2014
Either the picture for this product is misleading, or there was a piece missing from the order. The picture shows a plug with a gasket however, only the plug was sent (no gasket). Two emails to the customer service area regarding this went unanswered.

What's to say
by Scott from Chisholm, Minnesota on June 12, 2012
This does what it is supposed to do and that is stop the oil from coming out when in place and allow it to flow out when removed. Seems to work well!
