My boat has Captain’s Call diverters. Instead of electric actuators with a switch, I have to open the hatch and manually turn the valves to open or close my exhaust. Is it possible to add electric actuators to them or do I have to replace the whole valve/diverter set up?

call the people that make it
But guess is no
But with no pictures it's hard to say
i have seen people make up cables to run to helm, but again , fabrication, parts etc might not be worth the squeeze

Yeah, pictures would help. Genuine "captain's call" by CORSA are electrically operated. Never heard of anything that had a manual valve.

Years ago there was a system that used spring pressure/resistance to open and close the diverter. Closed at idle and would progressively open as you increased the RPMs.

This is what I have. Corsa diverters would be an easy swap, but I was hoping that all I needed was the electronics.

those dont look like any captains call i have seen
BUT< i can see with the pins, you could run cables, but that would be four into one belcrank then a cable to the helm... complicated but doable

and if your handy you could adapt some electric actuators,

these folks have lots of parts, maybe a phone call to cobble something up

Probably not worth the time to convert those to the Corsa operators as you would have to come up with something to mount the solenoid. After that, I would assume that the butterfly valve axle won't be compatible with the Corsa solenoid. Used diverters that fit in that spot are easy to come by and pretty reasonably priced.

those are old Corsa Captains call splitters, they offered those in the early 90s, you would have to weld brackets for the solenoids to be mounted on

Thanks for the feedback, I’ll have to start hunting for some parts

Probably cheaper and easier to find a used set with automated switch control.

I have a vacuum pump with pistons for my muffler butterlys, but they move with low effort. Not sure how difficult it is to twist the exhaust diverter?
