Motor is a 250 yamaha saltwater series 2
After idling motor for short period of time it runs very rough, when given full throttle it is like it is only running on a couple of cylinders. this has been going on for a couple of years now and I have had it in to be fixed several times and at times it seems better but always comes back to same problem.
Any ideas?
