Mobile Services

Mobile Service
Niemiec Marine, Inc. offers mobile mechanical service for routine maintenance and problems that may arise during the season. We have a fleet of on-road service vehicles equipped with tools and parts to service and support our engine lines: Cummins, Yanmar, Volvo Penta, Volkswagen, Westerbeke, Crusader, Universal, Scania, and Phasor.


Electrical Repair

Electrical work can be tedious and overwhelming. Niemiec Marine has service staff with the experience and patience to perform both simple and extensive electrical repair and rewiring. We provide proper labels and diagrams when wiring a new component or system on a boat in order to allow another service technician or the boat owner to troubleshoot problems years down the road with ease. When running a single new wire or completely rewiring a vessel, our electricians make sure to use adequate wire size and heat shrink and solder every terminal end. We do not use crimp on connectors — these fail over time.

Fiberglass and Painting

The fiberglass and painting technicians at Niemiec Marine are highly skilled individuals. These services are available for both structural and cosmetic work. We provide gelcoat and fiberglass repair and well as painting and gelcoat refinishing. In addition, Niemiec Marine specializes in grounding damage repairs. We focus on making your boat structurally sound, safe and back to factory finish standards.
