My 1994 60 degree 150 HP Evinrude is having a fuel flow restriction problem. When I started it yesturday the constant alarm started to go off about 10 seconds after it was running indicating a fuel flow restriction. I checked all fuel lines and did not see a kink. I could pump primer bulb after it was running which would firm it up again and make the alarm go off for about 15 seconds at a time but it would just start the process over again with the alarm going off. Did not know if this could be a VRO pump problem which is still hooked up or something else. Any help would be appreciated.
