I had an Imco Lower that Failed within the first 10 minutes of being installed on the first day of a 1 week vacation. I called IMCO to find out what I needed to do to get it replaced. They pretty much told me to pound sand. They were more interested in getting me off the phone before they even knew what my problem was!
Needless to say I took my Failed Imco Drive up to the boys at Max Machine Worx in havasu. They fixed it just to help me get back on the water. I Had them build me one of theirs, picked it up later that week, took the Imco off and it's still sitting in a box on my shop floor.
Go to Max Machine, Jason and Red are great and will deliver the customer service you'd expect on a big ticket item
