Yesterday I took the boat out, when I went to go up on plane, engines were sync'd, around 1800-2000 rpm the port engine RPMs began to flutter around moving lower than the Starboard. And it felt like we were going about half the actual speed we should be doing, around 12-15mph instead of 20-25mph. I think I could hear a different noise coming from the engine compartment but I'm not sure about that. What I did see then was a system error appear on the Smartcraft, I took a picture of it (attached) along with the two tach guages showing at that moment the port engine running 300-400 rpms lower than the starboard (even though engine sync was on).
Two questions:
- am I correct in looking at the error screen to be an error with the Port engine (I assume so, but just verifying as my local dealer has been focused recently on the Starboard engine)
- what specifically does "IMV Pressure Low" mean?
Two more interesting data points:
- we idled out to a cove after the problem happened and anchored, on the way home later that night I did another test and the boat ran *perfectly* all the way up to full speed. So the problem seems intermittent.
- a week ago I noticed that the Port engine overflow coolant bottle was filled to the very top (should never be), not sure if this is related or not.
Any thoughts/ideas?

Jason
