06 90 hp 4 stroke runs rough, not reaching rpms. replaced spark plugs, new fuel water sep. all spark plugs are getting strong spark. figure there must be a blocked/fouled fuel injector.

Is it easy to remove and clean the injectors? any other suggestions to check?

thanks

Re: 90 hp 4 stroke running rough

to close out this thread, i took off and cleaned the injectors, removed and flushed the high presser pump, bowl and filter, and reassembled. the gas was cloudy when poured into glass jars but got knocked over before allowed to settle.
after everything was put back together ran up fine. added Seafoam and will change fuel water sep after 10 hours.
