OMC controls

[rjoynt]

I am the custodian of a 1947 Aerocraft. Model DD I believe. I am attempting to put a steering wheel and controls on it. They will be located in the rear seating area. Throttle and shift controls on the starboard side. I have the steering wheel and necessary hardware. My question deals with the Johnson controls. I need to be educated on cables needed and length calculations. Also I need to get the throttle and shift controls at the motor. I prefer to get new if available. Also, suggestions on mounting the OMC control box.
Part numbers and manufacturers would be perfect so as to reduce the chances of getting the wrong parts. I have dealt with Crowley and marineegine.com before.
Thanks in advance!
Bob

Well, any of the OMC two lever controls will work just fine. So, I would look for a used two lever box, that has not seen salt water use. The length of the cables is another story. There is a formula to measure (roughly) for newer engines where both cables enter the motor pan on its stbd side…Your engine has connections on both sides of the stern bracket, so your throttle cable may need to be a foot longer than your shift cable. The control box you find might just have cables already installed, perhaps the length of the cables is still visible on the casings, you can use the probable excess length of these cables to determine the proper lengths you need….

This style of control works best, but is not "correct for early motors (but will work fine)

This style would be "correct" up to about 1960-ish.

If you do buy used, try to get a complete set, including cables. Reason: New cables do not include the cable ends, which you can remove from the old ones.

I have a used set like the 1960-ish, if interested.

I have the controls. I do not have the correct length cables. I would like a suggested manufacturer of new cables. Also, are the cable motor ends still available? Or do I have to use old ones? Part numbers of the cables would be most helpful.
Thanks.

maybe this diagram will help

Teleflex 400 series cables are available in one foot increments and fit all the OMC remotes from the early 1950s up into the 1970s, but like Frank said – you need the ends for the motor.

Here’s a handy list of them:

The general guidance I’ve read goes like this: Measure back from the control box (rear? centerline?) along the gunwhale to opposite the front of the motor, then to the centerline, then add four feet for looping the cable to allow for movement of the motor. Order cable of this nominal length, rounding up to the nearest whole foot. My sense is that this will give you a usable length but might in some cases give you a bigger loop at the motor than you really want, depending on the setup of the boat. Most cables have the length marked on the jacket a couple of feet from one end.
Cables these days seem to come in three grades, with the highest/most expensive allowing a smaller bend radius. As for ends, this a subject I haven’t mastered.
