Do not use them!!!.
Doug Mitten came to my sailboat to adjust the rigging and do a tune up on my Yamaha 9.9. He removed the carb saying that it needed to be rebuilt, which I unfortunately went along with.After he reinstalled the carb, and changed some electrical connectors the motor would barely run.I was having the boat hauled out for bottom work and Doug Mitten assured me he would return to sort out the damage he had done to my outboard. I called him the next day to arrange a time to meet in the yard, and he told me he was on the way. Doug gave me the run around for the next few days...finally telling me to get lost that he had no interest in correcting the damage he had done to the motor. I have since learned that he basically did more damage than is worth repairing.
I also have learned through the grapevine that Doug has a serious drug and alcohol problem...just the guy you want working on your boat.
I would mot trust him to put air in my bike tires let alone work on a boat.
I'm in the process of getting a lawyer and taking Mitten Marine to small claims court....DO NOT USE THEM FOR ANY WORK!!!
