1999 Evinrude Ficht 175. Starts and runs (low speed) okay. If throttle is advanced to about the point the boat would plane (no tach so don't know RPM) it won't go faster, surges a bit but never really gets going. If you squeeze the bulb it goes fine. Sometimes it keeps going, sometimes you have to keep squeezing. Pressure (at valve, rear of engine) 25lbs.
I tried a remote tank. I replaced fuel hoses, including bulb. All (fuel line) connections tightened. Replace fuel filters (external and internal). by-passed external fuel filter.
Based on what I have done (including connecting engine with short hose directly to small portable tank), it appears the problem is the engine, not fuel supply, but the engine goes fine if more fuel is supplied (by squeezing ball).
Ideas, suggestions?
Thank you.
