Marine Engine Specialist

Whether you favor a classic Hatteras Motor Yacht, a Tournament Champion Viking Sport Fish or a sleek
Euro Ferretti, A&M can Repair, Rebuild and Repower your floating masterpiece.

Who We Are & Services

Whether you favor a classic Hatteras Motor Yacht, a Tournament Champion Viking Sport Fish or a sleek Euro Ferretti, all boat owners can’t deny the infectious rush they feel when seeing (and showing off) their polished, pristine engine room as if it were a priceless piece of artwork. Many of the industries products are manufactured to a brilliant, lustrous finish to elicit that very rush.

Polished works of art are nothing new for A and M Marine as we continuously dazzle the industry with much more than just powerful, performance marine engine repair, rebuilds and repowers. The engines we touch become performance jewelry for your boat, becoming more valuable as we care for them.

Much of our clientele come to us because they demand the best service and know we overlook nothing. It is our attention to detail, high quality craftsmanship and passion for the marine industry which makes us unique. After we complete a rebuild or repower, our clients often comment that their engine room looks, and most importantly, runs better than the day they bought their boat.

Our clients can speak with us anytime, 24 hours a day, 7 days a week. We will even send you photographs and videos of our progress on your boat and keep you abreast of our schedule. We strive to be on schedule and are often ahead of schedule making our clients very happy. We have gone so far as custom building a shaft stuffing box, in our onsite full machine and welding shop, because we were given a manufacturers lead time of 8 months which was unacceptable to us. We built the box and completed the job in under two weeks, saving the season for our client.

A down yacht is a down client. We minimize down time by carrying a large inventory of new, used and overstocked spare parts in our retail store. With 25 years of contacts in the marine business we know how to track down parts and know how to get them delivered quickly. Our on-site full machine and welding shop and full woodworking shop enable us to bypass the subcontractors and do fabrication work on-site, minimizing wait times and minimizing cost.
