Hello eveyone,
My son has a 30HP 2 stroke Evinrude (1989) that we use for fishing in Mexico. It has developed a problem to where sometimes it will not want to acellerate from idle, and will easily die. However if I baby the throttle and get it going it will suddenly take off and as long as I hold it at full throttle it will keep going. We tried 2 new fuel lines and a new tank. It kind of feels like a fuel delivery problem to me, like it can't get enough fuel till it builds some RPM. My thoughts at this point are maybe a suction leak at the fuel inlet on the motor or fuel pump/carb issue. I got the motor on a stand and I am going to try and replicate the problem in the garage, meanwhile any ideas? Remember this problem is intermittant, sometimes it runs great, then later it will act up. Temperature makes no diff as it will happen hot or cold. At last years trip it ran great for 3 days then on the last day it acted up and we lost a whole day of fishing. That can't happen again.
Thanks, BigB
