Good morning- I've put about 25 hours on my 210 FSH now and have noticed a couple of things-wondered if it was common. I have a slight list to port while underway. If there is any significant chop and I'm running on plane, ive noticed the starboard engine cuts off repeatedly. Annoying more than anything really. Im assuming enough air is entering the starboard jet to cause over-revving and the engine is shutting off for safety.

Check your clean out switches. There may be some slop that is causing this

Are you talking about the switches on the hatch? Maybe the wires to the starboard switch is loose?
Yep. Lid is bouncing and tripping the kill switch on that side. (At least that’s my guess)

The hatch latches on my new boat had too much slop and need to be adjusted. I'd start with that latch.

Yes-correct, I can see in my mind that there is only one switch and its on the starboard side I believe. (not with my boat right now)
I believe people have tested the switch in chop by taping or attaching a quarter to the switch to make sure. They would run it in chop to verify.

I also had this problem.
I had to redo the hatch latch.
And raise both port and starboard switches about 3/4 of a turn.
-Look at the 2 switches next to each other and see if its visibly lower than port side?
-Took about 30min and was able to unscrew the entire cleanout compartment top on mine.
-Then try to leave the nut on the top where it is as a beginning reference.
-Then unscrew the nut on the bottom side 3/4 turn or however much you need.
-Then push the switch through and see how much more it sticks up (compare to port switch again )
-when it's where u want it , tighten up the top nut and done!
