Anyone know how to hook up this Livorsi exhaust?
The cylinders gave two ports, only one is needed as it is a spring return (open) I assume the other hose gets routed into the boat to prevent water from entering. I have jumped the compressor and I can run the compressor and trigger the solenoid. My question is, when this is switched “on” to close the exhaust does the compressor need to run continuously along with the solenoid?
anyone have one of these systems and have some information.
i realize they are filthy, everything seems to be in working order.
thanks

No. If the seals are good, the compressor will pump the actuators open and thus close the flaps.
You should use a 2 way momentary switch to run the compressor. One way will pump and the other will release the air.
If you hold the momentary pump switch longer it will build more pressure and hold them closed longer.
They will stay closed for quite a while, how long depends on how many rpms you are running.
You don't want water getting into the air release side connection either or it will corrode the inside of the actuators.

My CMI aft-fire mufflers have stayed closed for weeks. If the seals are good in the pump and the rams, they stay closed for a long time (I don't normally leave them closed). One way to help the seals in the rams is to spray a bit of 303 into the air fittings of the rams and move them in and out then lour out execss fluid. Pull the ram out, hold your finger on the air in fitting, the ram should not retract all the way until you release your finger.

Yes, and as Griff stated above, you will need a two way switch.
BTW, CMI now calls it 'External Sound Choice System.'
Yep, pressure as stated below. Simple system.

No, that is a pressure pump. When you energize the solenoid it releases the pressure between the pump and cylinders. The solenoid is normally closed. Your 2 way momentary switch... one side energizes the compressor the other energizes the solenoid.

so when you close the flapper to quiet it down it only stays closed for a short while after the momentary switch is fired? I would like to use this as I am coming out of the marina and down the no wake channel. Is that possible with this setup? I’m thinking a cable setup may be better for switching the flapper if the compressor doesn’t do it. I’m not exactly sure how these work as I have never owned one.
