Troubleshooting and maintenance of outboards and stern drives

We are in business to provide repair services for all types of boats, from small dingys to 65' yachts. From bottom painting to complete restoration, all work is done with two goals in mind; pride of craftsmanship and customer satisfaction. We have marine railway haul-out and Elevator lift hau-out capability, rather than slings, so wooden hull boats are not subjected to the strain imposed by the slings.
