This was my experience of them.When i bought the previous boat it had a 30 on the back,obviously i wanted to get it serviced before i used the boat,mechanic came down and did all the usual bits and pieces,gave me the bill,from memory very expensive,and then said get rid of that as soon as possible,you cannot get parts if it goes wrong,sold it or part exchanged it for a Mariner 60,that was a dog,swapped that and some cash and got a Yamaha 50,stuck with Yamaha ever since.
