88 mercruiser 5.7l alpha one water shutters
by Sam from Monticello, Iowa on May 10, 2014
Decent product, more restrictive than older design, less prone to breaking though. Note especially for the older casting y pipes, my new shutters did not just fit right in. My castings were not the same size as plastic ring and the plastic will break easily if forced. I had to hand file the y pipes to fit these replacement water shutters. But mine is a 88. Little hand tuning and mine fit fine, work very well. Might just be mine, but I thought I would throw it out there if I'm not alone with imperfect cast aluminum 4" oval y pipe.

Returning Items Through iboats a RIPOFF!!!
by John from Dixon, Missouri on March 21, 2012
I ordered this item for a boat, then sold the boat before they arrived. I had no issues paying the return shipping, because this was my choice. I simply wanted to get my money back for an item that I did not need. However, after following their VERY complicated return procedures, I shipped the item back in plenty of time, but was told by iboats that my return authorization was expired. So basically what happened, they took my item back, put it on the shelf, then told me that they never got it. DO NOT TRUST iBOATS!!! I have since bought a new boat, and will be buying ALL my parts from Jamestown Distributors or West Marine. I will never do business with these ripoff artists again...
