Paul got my boat in, fixed, and back to me incredibly quickly. He kept me in the loop throughout the entire process so there were no surprises. Top shelf operation. I highly recommend

Paul at East River Marine and his team are fantastic. I have brought my boat here for service on 2 separate occasions. The first, they had me fixed and back in the water in 24 hours. The second, I got a call at 7:30pm on a Friday night saying it was ready and I could have it back in the water for the weekend. Paul is honest and fair when it comes to servicing my Yamaha OX66 250hp outboard. I will not bring my boat anywhere else for service, maintenance, winterization, and spring commissioning.

Paul installed a new Yamaha 300HP on my boat and I would recommend his service to anyone looking for a Yamaha dealer. He is honest and answers the phone at all hours. Paul serviced my old 250 Yamaha prior to me upgrading to a new motor.

Top notch service. Was in a jam with tilt and trim problems. Called and Despite being buried in work, Paul told me to come down and he would get me up and running the same day. 1hr later I was driving home, problem fixed and with a new mechanic. Thanks again for everything. Very knowledgeable, incredible customer service, highly recommend East River Marine.

Been using East River for about 10 years now to get my maintenance items from and to have the more involved work preformed. I have to say Paul is top notch, always there to help and answer a question. I won’t use any other mechanic.
