Re: 2004 Yamaha 150 4-stroke RPM/bogging down problem

My boat did the exact same thing, and I spent a lot of money chasing problems that didn't exist as it was the injectors all along. I would definately get the injectors cleaned by a shop, I tried it myself by watching a youtube video and it made it a little better but didn't actually fix anything. When I took the injectors in they cleaned them and gave me a report showing how bad off they really were. They are really easy to get off, 2 bolts and remove the electrical connectors and fuel rail comes right off, at least on my engine anyway.
