Yamaha F150 4 stroke 2009

(Galveston, Texas)

Hello. I bought this engine new and have used it regularly until 2017 when our boating frequency went down. It has maybe 250 hours. A couple of years ago I took it out for a run and after 20 minutes at 3/4 throttle, the engine almost stopped, RPM was down, intermittent running, like it was starved for gas. Made it back to the dock. Replaced fuel filter. Tried again, same result after 20-25 minutes. Tried replacing the injectors, twice, with the same result. I have reached the limits of my mechanical abilities. The boat is in Galveston and absent a brilliant idea here that I can execute on, really need a referral for a solid, fair mechanic in the area.
