First of all I want to say I am a newbie to this forum and to the boating world...so with that in mind, I have a question regarding a boat I recently acquired. I basically bought the boat for the trailer but would like to tinker with the boat as my son wants a "project" for him and I to do. My question is in regards to the throttle control. When we got the boat the control was laying on the seat with all the wires unhooked so I am trying to figure out how they are connected. Stopped by my local shade tree boat mechanic who seemed a bit nervous when I told him it was a OMC and the year of the boat. Showed him the picture and he said it looked after market. Told me to come back in a few weeks when they weren't so busy. Looking thru a online parts catalog, picture shown did not match the one i have. Anyways.. what I am trying to figure out is if anyone can knows how or where i can find a schematic to figure out how to hook the wires back up correctly. Info on the boat is 1978 seaswirl with omc 185 model #990252J sn#W599576. Also has a number stamped on the control housing of M-1093-D2. A big thank you in advanced

aaaaaah, yes, it's an Electric Stringer drive,....

We've got a few Stringer Experts 'round here,...

Let's see what they say 'bout it,...

Bein' what it is, be Happy with the trailer, a Stringer drive ain't what ya want for a project,...

Re: 78 seaswirl remote throttle identification

I can't see the photo on my phone, but if its a electric shift controller, something is wrong. A 78 with your engine ID should be mechanical shift. 77 was the last year for electric shift.

Can you post a photo of your lower unit?

I would gladly if I wasn't 700 miles away from the boat because of work. Maybe i could get my wife to take a pic of it and sent it to me so i can post... but my understanding from what i have read, 1977 was the last year for electric shift but who knows it could habe been hill-billy engineered along the line. That's why I'm leaving it to you guys... the experts

If you happen to know if your water intake is on the trim tab just behind/above the propeller, then it's likely an electric shift ... Giving you something of a Franken-motor.

Okay - back at home: Here's what an electric shift look like -

I don't have a wiring diagram for that shifter though.

Re: 78 seaswirl remote throttle identification

Sorry it took so long to get back to thread. Work and a family wedding has had me occupied for a couple weeks now. Anyways..was finally able to get some pics of the outdrive. Hopefully this will help identify if|I have elec shift or the manual one. If any other pics are needed please let me know. Thanks

That is an electric shift and it appears to be a high profile drive. Not sure what the electric shift wire colors are supposed to be or if the lose wires in your other pictures are the right colors. ....but yes, the shifter has to make continuity with the coils in the lower unit.

PROBABLY! Maybe someone will chime in with a wiring diagram and hopefully those lose wire will conform to it. Otherwise you will have to trace them back to the outdrive wire harness to determine which is forward and which is reverse. Even then, I do not know how you will attach those wires to that goofy throttle/shifter control.

Re: 78 seaswirl remote throttle identification

I can't figure it out in my stuff ... I think that's the single mount side controller, but i can't make heads or tails outta' the pictures. Try HERE for some diagrams and manuals.

I'm sure you can short the system out, but I know people wire replacement/make-shift switches up too.

Re: 78 seaswirl remote throttle identification

Ayuh,.... I donno nothin' 'bout the wirin' of a Stringer, but the controller is kinda obvious,...

It's a converted ole Morse controller, an electric switch is bolted in place of the second cable,...

The switch appears to use the 2 terminals on 1 end for forward, 'n the opposite terminals for reverse, with the center set for neutral,...
Movin' the handle oughta point out which end set is for which direction,...
I imagine a contact inside unites the terminals on each side, opposite each other,...

I would "Guess", power is fed to 1 side, 'n there oughta be 3 load wires,..?? F, N, 'n R,..??
The hole in that theory is the red wire in the picture, lacks another connector,...

Re: 78 seaswirl remote throttle identification

On the ES Stringer the green wire is Forward and the blue wire is Reverse. Later units ('78 would count) had a white lead which is a Neutral cut out to prevent the system from cranking in gear. Basically, if the switch on the controller is allowing juice to the lead, you are engaging a gear. No juice, no gear. So, I'm not sure how important the neutral lead is.

The way my controller is set up is with a switch that the lever activates energizing the correct gear lead. If Bond-o's ID on the controller is correct, you've probably got a little rural engineering going there. I've seen Howard Sterndrive suggest this switch:
2X441.jpg
But I don't know much about it installs.

There are a few different OMC electric shift controllers out there.

THIS is the controller that mine ('72) uses. THIS is the binnacle mount. THIS is the side-mount. I believe you can use the old 3 button rigs like THIS guy too.

Still staring at the pictures to see if I can get it ... but I really stink at this kinda' problem solving.

Re: 78 seaswirl remote throttle identification

first of all I would like to thank everyone of you for your comments and advice. I did a little more digging and found another green wire with a terminal end on it hiding in the wiring harness.so what Southkogs said is starting to make sense. Bondo's advice is making sense as well to wear each end of the electric switch being 1 for forward and the other for reverse. would I be safe to assume that the middle terminals on the electric switch are for the two white neutral cut off wires? would it be safe to splice the two white neutral wires and install a jumper wire for the other neutral warm ups switch or is this redundant. once again thanks for all the advice!

Re: 78 seaswirl remote throttle identification

I don't have the neutral wires in my setup. Not sure how they work or what the risk is to zappin' the shift wires.
