About Longitude Marine
Longitude Marine operates as a marine diesel repair specialist in Saint Clair Shores, Michigan, holding a 4.7-star average across 13 customer reviews. The business serves boat owners throughout the St. Clair Shores area and Greater Detroit region, offering both in-shop service and mobile repairs at client locations. Their service menu covers marine generator systems, air conditioning units, and diesel engine maintenance, with particular expertise in Yanmar propulsion engines.
What distinguishes Longitude Marine from general marine shops is their focused dedication to diesel-powered vessels and the parts inventory that supports immediate repairs. The shop maintains an online parts catalog, allowing customers to order components before arriving for service. This integrated parts-and-service approach means technicians arrive with necessary materials rather than delaying work for parts to arrive.
Customer reviews highlight specific technicians by name, with Steve frequently mentioned for accommodating urgent requests and explaining technical issues to boat owners. Reviewers describe experiences where the team resolved generator problems that previous contractors could not fix, and one account details Dwight performing a complete fluid change and impeller replacement on a 2005 Yanmar engine while patiently answering owner questions. These scenarios demonstrate the shop's willingness to handle complex repairs other shops had abandoned.
