Hello everyone, I have a 2008 Yamaha F150 engine on my 2008 clear water dual console. Currently I have replaced my fuel water separator, my F filter, my PCV filter, cleaned my injectors, and pumped my tank. However my motor is still running rough and is having trouble holding any RPM above 4500 and is shaking at lower RPM. Any insight is greatly appreciated.
