Whether you're maintaining a fishing boat, cabin cruiser, or work vessel, it’s essential to keep your marine transmission running smoothly. At Northeast Transmission Inc., our team is trained to diagnose and service a wide range of marine drivetrain systems. From seasonal maintenance to full transmission rebuilds, we help you stay on course with expert repair and strong warranty options.
Our shop services most major marine transmission brands and models. We use marine-grade fluids and OEM-equivalent components to ensure lasting performance and dependable operation, whether you’re on the lake or at sea.
We understand that marine transmissions are built differently from automotive systems—water-cooled, designed for lower RPMs, and often more complex when it comes to repairs. That’s why our technicians are equipped with the right tools and experience to diagnose problems accurately and perform repairs with precision.
Common Marine Transmission Issues Include:
- Delayed or slipping gear engagement
- Vibration or noise during shifting
- Leaking seals or fluid contamination
- Overheating from poor cooling flow
- Worn or misaligned couplers
Our Process Includes:
- Complete system inspection
- Diagnostic testing and reporting
- OEM or high-quality replacement parts
- Alignment and function testing before return to service
Whether you own a single boat or manage a fleet, Northeast Transmission Inc. is your trusted marine service provider. We proudly serve both recreational and commercial customers across Maine and the surrounding region with quality repairs, reliable turnaround times, and honest service.
