About the noise: All petrol machines are loud, we have not tested the decibels, but the noise is the same as the motorcycle, so it's a normal phenomenon. 2. The machine itself is lightweight and can be used up to a boat weight of 100 kg and a load capacity of 4 people. However, the speed is certainly not the same if a person is on it or 4 people on it. Customers who expect high expectations of the pace If you do not do the following: avoid a cylinder rating: 1, start the engine on the shore 2, use the engine if it no longer comes out of the water. Even if you want to test the engine, this should be done in the river! There is no idle, only idle or low speed ONLY FOR PROFESSIONAL USE Please note: wear parts (starter) are not delivered free of charge.
