Maintenance for all engines and transmissions

We provide flexible, fast and cost-effective maintenance for all engine types.

Millog Marine & Power provides expert maintenance for all industrial engines and motors, power plant machinery, heavy work vehicles and bulldozers as well as different transmissions and clutches at our workshop in Hämeenlinna. We also repair car engines.

We maximize engine lifecycles by assessing maintenance needs proactively and cost-effectively. We always go through service needs, timetables, and cost estimates in detail with the customer to ensure there are no surprises or hidden costs.

We also repair engines and transmissions on the road or at any other location through our field services.
