My power tilt and trim was not working. My marina mechanics couldn't fix it. I brought it to Paul who immediately started the repair. It was done the same day! Paul is amazing and I will never let anyone...

I have a 2003 Yamaha motor, with a problem. Paul immediately volunteered/ took me to show me a similar motor. His effort led me to easily resolve my problem. I wish six stars was a rating option!
