Hello, I am in need of a good out board mechanic around the rochester area. I have a 1995 johnson V4 120 that i have been haveing issues with. I have brought it to a mechanic that charged me $ 350 ( took 2 months) and it still has the same problem. I brought the boat back to them again , they said they fixed it but stil has same problem. The issue is that any thing bellow 2500 rpm it sounds real rough, bearly stays running. almost like its missing a cyclinder. Seems perfectly fine while motoring. Can any one recomend a mechanic? Or something to try? Thanks
