Hey Glenn,
What do you make of this?  We just make a long nasty trip back Montauk, NY last night and towards the end of our 100 mile journey the port motor starting surging/dropping RPMs.  At first, I thought we hit something but both motors' brackets have equal play/movement.

The two tanks had only about 80 gallons combined in them but I've had the reserve down to 50 without issue. Perhaps a clogged filter.  No Codes just the bouncing motors when I tried to run over 4500 RPM. 

It was late so Didn't have time to diagnose.  Any initial thoughts.  New Motors with just 75 hours. 
Thanks,
Anthony

I had that happen on the 300s.  I thought that problem had been repaired on the 350s?  I'll go check it out later!

BTW, I updated my membership.  ——DONE———THX

Thanks,
Anthony
