I've recently had an issue with my 2007 Grady White 306 Bimini with Twin Yamaha F250s. I've been getting an alarm whenever both engines go over 4000 rpm with the boat in gear. No alarm over 4000 if in neural or if motors are run individually. I've also run YDIS and gotten no codes for either engine. The alarm is not coming from the ignition buzzer, but from a black box attached to the wiring harness coming from the 704 Remote Control.
I've posted the history of the issue at: https://www.thehulltruth.com/boating...-4200-rpm.html , and was hoping for some more help here. The alarm/buzzer is coming from the black box in the below picture. There are two black wires coming from the box, one of which is spliced to two light green wires and the other a single light green wire. Can anyone explain this issue?
