Please help! !! I recently bought an 89 Suntracker party barge with an 90hp Evinrude 2 stroke outboard. I recently disconnected the vro. . However I'm having a problem. . Starts up quick, idles great, when power up to plane, around half throttle the motor bogs down... and eventually dies. If I put it in neutral it revs up full power And which boggles me if I put it in Reverse I Can Full Power It with no bogging!!!! I have checked all fuel lines and nothing is restricted. I run 50 to 1 also. Please help!
