I recently purchased a used Mercury outboard and paid to have it installed on my boat. The motor itself appears to run well, and the shop provided compression numbers and service records before the purchase.Unfortunately, my overall experience was disappointing. During the installation process, I was advised that the wiring under the dash was messy based on the previous motor setup and was asked whether I wanted additional wiring work performed. I declined because, despite the appearance of the wiring, all of my lights, accessories, and electrical components were functioning properly prior to the installation.When I picked up my boat, I found multiple electrical connectors left disconnected in the battery compartment that had been connected before I dropped the boat off. As a result, none of my boat’s electrical accessories worked after the installation. I contacted the shop and was told there were wiring concerns and that they were not going to perform additional work for free. At that point, I felt I had no choice but to have my buddy and me inspect the wiring ourselves rather than pay additional diagnostic charges.After checking everything, we found that not everything that had been disconnected during the motor installation had been reconnected. Once the disconnected wiring was properly reconnected, all of my lights and electrical accessories worked again. Had everything been reconnected correctly during the installation, there would have been no additional troubleshooting or expense.I was also disappointed to learn that parts of my old Evinrude setup, including the wiring harness, had been discarded. I had previously been told that my Evinrude would not be accepted as a trade-in, so I expected all of my old equipment to be returned to me or, at a minimum, discussed with me before anything was thrown away. After being told some of the parts had been discarded, I had to continue asking questions in order to recover additional items that belonged to the Evinrude setup, including wiring and control-related components.In addition, my old Evinrude motor was not returned when I picked up the boat and I had to follow up to recover it. I also discovered a fuel line compatibility issue after getting the boat home that had not been completed before pickup. While the shop did provide a primer bulb and fuel line afterward “ to make it even “, that was not my primary concern and I communicated that .The Mercury motor appears to run well, but the communication, handling of my old equipment, and the incomplete reconnection of my boat’s wiring left me very disappointed with the overall customer service. I expected my boat to be returned in the same working condition it was delivered, with everything that had been disconnected during the installation properly reconnected.I have attached photos showing how I received my boat back with the electrical connectors disconnected, as well as photos after my buddy and I reconnected them. Once the wiring was restored, all of the boat’s electrical accessories functioned properly again.Based on my experience, I cannot recommend this shop from a customer service standpoint.
