@HELP
Any updates or resolution with this?
This has happened to me twice thus far this year. Both scenarios have been identical:
At launch, both engines start & run fine, no issues. idle, stop, start etc.
After running (stopping & starting without issue), will go to the beach, anchored in 3-4 feet of water and sit for 4-5 hours on house power running stereo etc. Upon departure, (voltage is fine for both house and start @ 12.4v) both engines start, starboard engine has no issues, starts and idles at 1200 RPM. Port engine will start and idle at 1000 RMP. Upon engaging both motors to full power (either individually or single lever) port engine maxes out at 2000 RPM. No issues with starboard.
I will turn the key off, fully power the boat down and let it sit for 10-20 seconds, power everything back up, turn on the key and start both engines and the port engine will go back to normal idle at 1200 RPM and have full power back.
It is throwing a port engine alarm and diagnostic code (which I cant see specifics, just the code
#)
New plugs this season, there is no blockage and coolant is running through both engines, seems to be an electrical gremlin somewhere...
Any help or place to start would be greatly appreciated, dealer is 3 weeks out...UGH!
