Thanks- I was thinking of making something exactly like that.

Mine use Shakespeare or equivalent through hull fitting for VHF antenna coax for the air lines to the mufflers. Chrome plated brass with rubber seal. Newer pneumatic actuators from Parker on Amazon for $30 each use only one air line. Makes for a cleaner look. I'll try to upload a pic.

I thought about using the VHF fittings, but 8 of them would have been too much. I just ordered 4 custom plates like ICDEDPPL has on his boat.

Where did you get the 4 custom plates from?

J'achète du kit en France, les volets doivent être verticaux ou horizontaux? , J’ai installé des vérins électriques à l’intérieur du compartiment moteur, des coques usinées pour laisser passer une tige reliant le cylindre au silencieux.

Metals Cut 4U, I had them make 4, 1"x 2.5" plates, with polished stainless, 1/8" thick. I have a drill press at my house, so I'll drill the holes here.

I buy kit in France, the shutters must be vertical or horizontal? , I installed electric cylinders inside the engine compartment, machined shells to pass a rod of the electric cylinder to the muffler.

Some other options:
