I have a 2003 Yamaha F115 4 stroke. I have changed all of the filters, injectors and VST screen. I got in the water yesterday and I can't get past 2300 RPM's. Can anyone help?
 
Hello Frank
Give us a little more history on your motor. What was the reason you change all the filters and injectors?

I just purchased the boat so I decided to give it a tune up. Filter"s ,oil,lower unit general maintenance. The boat was sitting all winter at the Marina. When I started it for the first time out of the water it ran well, the second time it ran rough and the third time it would in turn over. I pulled the injectors and they were clogged. I installed another set of injectors and the engine ran well. I put it in the water the other day now I can't get the rpm's up under load.
