Old Towne Marine

When it comes to marine diesel engines and generators, Old Towne Marine brings something the Annapolis area has been missing: deep, dedicated expertise backed by decades of hands-on experience.

Founded by Jeff and Justin Leitch, Old Towne Marine was built specifically to fill the support gap for Yanmar engines and Northern Lights generators in the Chesapeake region. As an authorized dealer for both brands, they offer new engine and generator sales, service, and parts — all under one roof.

What sets Old Towne Marine apart is the team behind it. Jeff Leitch and senior technician Mike Montgomery — a familiar face from several respected local boatyards — bring a combined 90 years of diesel experience to every job. That's not a typo. When you bring your boat in, you're getting judgment and skill that can only come from decades in the field.

Their services cover the full range of diesel propulsion needs:

• New and rebuilt engines, generators, and transmissions

• Authorized Yanmar and Northern Lights sales and service

• Extensive parts department available by order with pickup or delivery

Old Towne Marine is setting up at 124 Bay Shore Ave. in Eastport — the historic home of Bay Shore Marine — with their storefront expected to open by Spring 2026. Parts are already available now on a by-order basis.

Whether you're dealing with a failing engine, planning a repowering project, or simply need hard-to-find parts for your Yanmar or Northern Lights system, Old Towne Marine is the kind of specialized, no-nonsense shop the local boating community has been waiting for.
