Our team

Meet us

North Wielkopolska is rich in lakes and rivers. It is known for the great Wielkopolska loop which can be reached by “water” to Berlin. When we find ourselves in the German capital, motorboat Europe is open to us. The formation of Wielkopolska caused a very large development of water tourism, and with it the demand for maintenance services for all kinds of floating equipment. And that’s how our service was created. The originator and owner is Szymon Nowak.


The GTWMARINE service was created in 2009. The next step was to obtain service and dealer authorization for global players such as Mercury, Mercruiser and Evinrude.

We serve private clients as well as institutions such as Rescue, Police, Fire Service, and Regional Water Management.

We own and provide a rich warehouse of parts, subassemblies and equipment for boats and engines.

We constantly improve our qualifications by taking part in trainings. Unexpectedly, thanks to our commitment, we are a leader in the repair of many brands of jet skis.


We provide our clients with:

  • Warranty and post-warranty services of outboard and sterndrive engines
  • Jet ski post-warranty services.
  • Sale of spare parts and boat equipment.
  • Mobile service with access to the customer.
  • Our services are carried out on original parts and diagnostic systems with the latest software.
  • It is also worth mentioning that we provide technical support and cooperation with a local leader in the sale of new boats by DEDI MARINE from Wysogotowo near Poznań.


Szymon Nowak


I am a person practically born from birth connected with powerboating sports, international technical judge actively judging competition in the country and abroad. My “love” to the water was handed over by Father Remigiusz, the coordinator of the Chodzieski Water Rescue Team rescue team, serving most of the events in the country and abroad in terms of rescue and medical protection. We have one of the best polish rescue units at Lake Chodzieskie, which we use to train rescuers, powerboat pilots and personally to test units repaired by me.


We cordially invite you to take advantage of our services.
