I have used Tony's Marine II (2 Tony's) three times so far, and I will go back. One repair was a water pump impeller on a diesel boat generator. It was difficult to access, and they gor it done efficiently. They also flushed the cooling heat exchanger as they advised that could be necessary. Another time I had them help with diagnostics on two diesel engines for my boat (Yanmar). This was also a good experience. Recently I had them change out two oil lines deeply burried in my engine and bay, and to the outside of the engine making access difficult. Again they di a good job and at a reasonable price. They are not cheap, but you get what you pay for, and the quality and professionalism is good. read more
