Concur with gt, I also don't recommend Mercrestor... I think I'm one of the three individuals that he referenced, that had issues with a remanufactured motor from them. I purchased a remanufactured Merc 115, here is my .02
First, the overall finish was impeccable... except the lower unit paint, which was of poor quality and didn't hold up to the least amount of transom saver use... I had to constantly tough up with a rattle can. The lower unit looked horrible after a short time.
Second, it is my opinion he does not properly test the parts or motor itself after finished, or inspect many of the old parts he uses on these motors as stated... a) the trim switch on my controls was obviously worn out from the start and did not work properly. He did send me a new one, which I installed and it worked fine after that. That could have been avoided had he even looked at it. b) the tilt/trim bled down on me overnight as it did with the motor gt mentioned. I lived with it due to cost issues as stated above.
Third, on the 9th hour of a 10 hr break-in process, the motor bogged down on me and would not advance about idle. After traveling 2.5hrs to a mechanic that I trust to fix the problem, it turned out that the stator was bad. I had a nightmare trying to work with MercRestor to get any warranty support. After struggling over this with multiple phone calls with myself and him talking to my mechanic even (i.e. the attitude issue mentioned above), I was able to get him to at least agree to cover the cost of just the part (stator). However, he only sent me what "HE" could get the part for (it was ridiculous low), which was half of what I paid for the part myself... and got it at a decent price and drove 20 miles to pick it up myself. So, all the travel, labor, and most of the part was on me. Not anything like what the warranty stated.
In the final analysis for me, the motor was strong and ran great, but had some issues with it that cost me some bucks, well above the initial large investment. One of the reasons I bought the motor from him, was that I thought I would "know what I have" and avoid a lot of these issues. It didn't turn out that way and I will never purchase another from him, nor do I recommend this to anyone else.
Just my .02
