Speeditwin 6039 Remote Controls?

[sedover]

About to receive a 6039 Speeditwin.

Would love to set up with remote controls.

Did Evinrude ever offer a kit or were we left to our own inventiveness. Since I don’t need to shift any two handled control box could be configured to work once the throw is worked out. Yes, I am planning to have a lever for spark and carb.

On the steering front was there any bracket system that has been used. I have a pulley steering system in place on the boat now.

I would use a dead man throttle with Bowden cable.

Steering bar to be attached to the rear of the motor somewhere?????

Evinrude only made remote controls for the electric start model. This included provision for starter, choke and throttle. I use a dead mans throttle on my Speeditwin for speed control, and use longer back studs holding the crankcase to driveshaft housing to include a steering bar. The steering bar also makes it easier for two to handle the motor.

There were aftermarket steering to attach in place of the tiller and control from inside the transom. Can be made from 3/4" round stock flattened on ends and bent to follow as needed. I could mail you a sketch for what works here. I can probably get a photo of the aftermarket adapter for the steering I am also using.
The throttle is controlled by a dead-man throttle, and the spark is adjusted by hand. You have to be close enough to start it and adjust the carb, anyhow.

Fortunately the Speeditwin, Speedifour and Big Four all have the same tiller bracket coming off the motor. That allows you to fabricate a, for lack of a better word, tiller adapter that will fit all three. I’m posting a picture of my Big Four. I fabricated the arm and machined it for an OMC cable adapter. That makes changing motors simple.

Hopefully the picture is easily understood.

Thanks everyone.

George, great pic. Gives me food for thought.

I think I can use two cables, one to advance both the spark and the other the carb. It is a matter of a clean effective design. I was planning to use the shift for the mag and the normal throttle for the carb.

The approach will have to be one where there would be no permanent alteration of the engine components other than changing out a stud or two. I might pick up a spare front cover/cowl if there might have to be a modification to accommodate the cable set up.

Though easily changed the boat has an OMC engine style steering connector/pulley unit.

It sounds like you will be running the rig farther away from the motor than usual, and by that I mean the location of the helm station. While having a control for the advance is nice, if you’re sitting close to the motor, there’s really no need for it as there are basically 2 positions for the mag; advanced and retarded. But if you are sitting too far from the engine to control that, you will also need to factor in a kill switch, as the kill button is on the mag lever, which you won’t be able to reach.

Steve;
If you are planning to use a two lever OMC throttle/shift control I doubt that the shift lever will have enough travel to effectively control advance and retard. Perhaps a bell crank might gain the needed motion. I would also reccomend a stop to limit advance so that a remote control of the spark advance can’t over advance the spark and cause pre ignition that might result in a burned piston.

First, I have not received engine as of yet. The deal is closed just working out pickup. It’s a very well kept original with spares.

Regarding the posts;

Good points and I have taken them into consideration, thanks. Yes, I will be beyond an arms reach from the engine.

Regarding spark advance; plan to look at current mag stop and that will be maintained via cable and whatever mechanism is required to make it work. If I have to make a new mag stop or not, we’ll see. I am also capable of determining the maximum advance via a dial indicator so that it is not exceeded.

Regarding the kill switch, most likely, especially with a non gearshift engine of twenty some hp, easy task. Looking back to the past, since many of us grew up running engines without ignition kills, shut down was no problem as we retarded the timing and carb to shut it down just prior to our landing point. If we misjudged we either hit the dock or paddled the rest of the way. As with most of you, did it both ways.

Current plan is to use a control box with 33C cables and required adapter ends. With 33C ends at the engine it leaves me a variety of approaches to interface with the engine as far as cable ends. I am also considering the late 50’s Evinrude box, it’s a matter of how it lays out. Must be clean, look good, and actually work.

Once done, I wonder if the Coasties might have a problem with the fact that the "neutral safety" doesn’t function except when the engine is off. How did we as a society ever manage to get this far.

Thanks again.

Steve
