A Word to the Wise:

Great Lakes Marine (GLM) only provides service at our facility, by appointment, through the main contact number or email.  There are certain individuals who might misrepresent themselves as authorized agents of GLM, and offer to conduct service outside of our normal business hours and/or not at our location.  GLM  will always provide a receipt from GLM for any business conducted with us. GLM will only take payment addressed to Great Lakes Marine never to an individual.  If there is ever any doubt whether someone is conducting business on behalf of GLM, please do not hesitate to reach out to us at info@greatlakesmarine.net or call 303-791-6100.  GLM is a licensed, bonded, and insured boat dealership unlike many mobile services or independent shops.  GLM has been in business since 1976 and has always stood behind the work performed at our facility by our employees.
