Hello,
Engines are 375hp 3208 TA.
Cruising peacefully this morning in Alaska, synchronizer is ON.. then all of a sudden the SB engine starts revving out of control, RPM gauge goes to Zero. Port engine is all normal. I turned off the synchronizer, turned off SB engine.. Checked in the ER, all looked fine, EGT, oil pressure, engine temp, belts, etc.
It seems that the RPM data input to synchronizer from the SB engine is lost.. Synchronizer thinks it’s at Zero RPM and revs the engine. Also, The RPM data is longer feeding the dash RPM gauge. I checked the cable from the SB engine to synchronizer.. it seems plugged in fine on both sides, no obvious damage or such.
Any advise or help would be appreciated.. To start if I can get the RPM dash gauge to work, that would be very helpful to match the throttles at the helm and keep going until I dock somewhere.
Thank you
Streff
