I have a new to me 2013 F115 Yamaha four stroke I have just mounted rigged and water tested. I have not connected any gauges. It starts and idles perfectly, after about 1-2 minutes of run time the key alarm comes on and won't go off. and it won't idle up and begins to cut out. Probably going into "limp mode"? I initially thought it was a fuel delivery problem and bypassed my backflow ball valve on the fuel line. No change after putting the fuel line directly into the tank. I have the removed the fuel filter on the motor and it is clean as a whistle. Alarms continue. I can get the motor to rev high fine if I disconnect the shift linkage and engage the throttle at the helm. Which is frustrating. I have put fresh oil in and was slightly over full from the 3.9 quarts mentioned I added 4. (why doesn't Yamaha put full and low marks on the stick??--for another thread). Water pump seems to be working fine and "P" tube has good steady flow. I have read some threads about battery, but this one has 12.5 volts and starts and idles fine (with a small automatic up idle at start up). Any additional suggestions to check would be greatly appreciated. Also, I have not checked the VST system? Where do I look or suggestions. I also need to check the high pressure fuel filter but need to look where it is. I know it is downstream of the fuel pump (the round thing with the two fuel lines going to it with three screws) My routing runs up near the flywheel from there so I need to take the fly wheel cover off to see it. I plan to connect the gauges tomorrow and see what pops up.
