Good product on time.
by Marlin from Holmesville, Ohio on July 24, 2017
Quality was good. It was really hard to get on as it does not stretch all that much but a buddy told me there is a tool available that makes it a lot easier to get on. I would highly recommend getting the tool if you do not have it.

Alpha1outdrive bellows
by Timothy from Spring Hill, Florida on April 21, 2012
The bellows is correct, but it is almost impossible to install with outdrive still on the boat. You need a lot of patience. I finally got it on and clamped, but not without finally figuring out what end had to go on first ( transom) . Now that I know, the next time won't be as difficult

It can be installed with motor still on.
by Jerry from Carbondale, Illinois on June 09, 2011
It was tough to put on, but if you have the motor just right you can install this bellows without removing your lower unit. The bellows itself seems to be made of good material.
