Engine Controls

I take your word on SFs, because in my neck of the woods there aren't many around.
But I did come across several Kobelt controls in fast MYs (both OEM installed and retrofitted), obviously also in the f/b, hence much more exposed to weather than in the main helm.
Some of them were 20+ years old, and the worst I've seen happening to them is that the control head at the base of the levers loses its shine and looks worn out, in the chromed version (as opposed to the more durable black version).
BTW, Kobelt controls can also be interfaced with their own wired remote, which is somewhat ugly but very solid, and allows full control of everything: gear/throttle/rudder/thruster.
Which for all intent and purpose, can also replace a fixed third station.

At risk of stating the obvious, another thing to consider is that with electronic controls you lose the separate levers for gear and throttle.
Which many folks hate, but most of those used to them (myself included) prefer them to single levers every day of the week and twice on Sunday!

I obviously went with single lever side controls for the PB helm setup. But I do recall that I could have gone with independent throttles and gears, say had I set up a second station aboard. The flexibility was available with Kobelt.

edit: In looking quickly at their web product guide it doesn't;'t appear that they offer separate throttle and gear units today. Perhaps that's a bad memory or a change in their line.
