very good shopping experience
by Alan from Leesburg, Florida on June 15, 2011
Not only were the impellers exactly as stated and fit perfectly, the super fast shipping that iboats.com utilized was unexpected, especially since I chose the least expensive method of shipping..the USPS. I received my impellers in a matter of a couple of days. WAY TO GO iboats.com! I will use them for any future part purchase.

Cotter Pins
by Steve from Algonquin, Illinois on June 15, 2014
I ordered cotter pins with my new prop and hub kit and when I unpacked my package, I totally forgot about the cotter pins and recycled the box, cotter pins and paper insulation in all. In the future, I would suggest that you tape smaller parts to larger boxes so dummies like me won't toss them out.

Replacement Trim Tab

threads
by Ron from Happy Jack, Arizona on January 23, 2016
I was very happy with the service.The new tab had a different thread than my old anode.This could have been due to the old owner of the boat replacing it . The new tab had fine threads ,where as my old anode had course threads.I was able to drill it out and rethread it,thus it worked fine.I think it would be a good idea for the manufacture to include a new bolt with the replacement trim tab.
