Electric shift was OMC................. WHat about the OMC stringer, DOH

How did the electric shift work?

I could see a "Mad Max" electro magnet thing but could it be strong enough?

Definition of Crash Boxes
 

Keep in mind that for brevity I am simplyfing the definitions.

Marine transmissions that we are used to seeing, like a Borg Warner C72 for example, have clutch plates built in. The clutch plates are activated by hydraulic pressure to engage and disengage the drivetrain. This is what allows you to shift while the engines are running.

Crash boxes are similar to a manual automotive transmission much like a Muncie M21 in that they do not have internal clutches. (Although most marine transmissions only have one forward gear, although some have two) So if you try to shift your old SS 396 Chevelle into gear without using the clutch while the engine is running, you are going to hear some nasty grinding noises because you didn't use the clutch. So just as shifting without using the clutch is not feasible (someone is probably going to argue about speed shifting a car, but I'm just making a simple analogy), you can't shift a crashbox without shutting the engine off.

Although if you do shift and hurt your crash box, John Klumpian at Doller Offshore is excellent at rebuilding crashboxes, drives, and transmissions.

A transmission with no means of smoothly engaging into gear, and no clutch to disengage it. Imagine you have a standard transmission in your car and you are trying to shift into reverse. Without a clutch you'd have to turn the engine off, shift it into gear, the start the engine again, and you're off and rolling. Crash boxes work the same way - no clutch, no synchros.

is there a difference in the cone clutch trannie in the NXT drive vs their bravo drive set up. What makes the NXT handle more power vs the Bravo's. Thanks Jeff

There is, I will let the others explain..........

We used to have an old sea-ray with an electric shift OMC. I'll never forget when it malfunctioned leaving us only with reverse and we had to back across the bay in 4ft seas and through the middle of a sailboat race.

Thanks, but go ahead.. Im just trying to understand it better. This is whats on my next 4300, NXT drive and transom assembly with a #6 drive vs the nxt drive. I know there is 2 shafts vs 1, any other diferences, or tollerances. Thanks Jeff
