Engine repair service near Marathon, FL

All Keys Diesel Repair removed our Generator from our Boat on Oct 23, 2015 for a broken bearing in the back end unit, Stated it would be reinstalled in 1 week. 1 month later it was reinstalled and they broke off a brush during re-installation. Part ordered. 1 1/2 weeks later brush was installed and generator lasted less that 5 hours. Generator was pulled again. 2 months later generator was re-installed and lasted 15 days. In the process, shorting out all 14 brand new house batteries and a $5,000 invertor. Contacted All Keys Diesel mechanic via facebook since we were in the Bahamas. He gave me suggestions on things to try which did not work. Contacted All Keys Diesel mechanic by phone exactly 90 days from re-installation and he asked me to try something else which did not work. Contacted the owner and he stated it was no longer in warranty and my contact with the mechanic did not qualify for "notifying the company" so he would not honor the warranty. I am out of over $10,000 out of pocket and have not had a working generator for 8 months. They will lie to you continuously. DO NOT USE ALL KEYS DIESEL or Keys Diesel or Florida Keys Diesel as they all appear to be the same company
