How Fast ?

Re: How Fast ?

Under the inspection plate on the exhaust housing, where the brass shift connector is, check this. The upper, and lower shift rod where they go into the brass connector has a notch turned in it, This notch on the rod must mate up with the pinch bolts of the connector. If not, the linkage will be out of sync.I'm at a loss why the shift linkage is off, but the photo's appear likethey are at the end of the travel.

Re: How Fast ?

I checked the brass connector again last night and it looks good. No play in the linkage when shifting. I had someone mention something about a fuel saver on some of these old motors. Anyone know anything about that and wether it could be related? I don't know what else to do.

The engine will go into full forward with the shift cable disconnected won't it? Will the throttle then fully open the carb?

Re: How Fast ?

On that shift connector, the shift rod has to go in far enough that the retaining bolt goes thru the notch cut in the shift rod. I have seen it happen where the rod is just pushed into the connector, and tightened, this will throw the linkage off. In the photo, it look's like the plastic furrle on the shift connector is bottoming out on the anchor point on the engine shroud. I'm also at a loss, but something simple is being over looked here. Is your remote control an OMC?

Re: How Fast ?

Yes, if you remove the cable the motor will shift to full forward and the throttle will shift to WOT. The remote control box I have is an Evinrude Simplex box with the dual handle. I have measured the cables with two other sets with the core wire pushed in flush on one end with no connector the other end measures about 4 5/16" or so on three cables I've checked. I agree there has got to be something simple being over looked. I just can't seem to put my finger on it. The only thing I have not tried yet is to take the connector out of the control box and see if I can pull it by hand forward to make the shift lever go into full forward. If so cable must be to long. I'm going to try that this afternoon.

Re: How Fast ?

I took the cable out of the control box and pulled it as far as ot would go and it will not shift the motor to full forward. It bottoms out in the connector @ the motor end. Is it possible to have the wrong connector an still hook up properly? I have a 1957 18 hp evinrude and I measured from the center of the pin hole on the lever in neutral position to the cable bracket on the cowl and did the same on the 30 hp. They measured the same about 6 1/4". I don't think there is anything wrong with motor setup. It shifts fine without the cable hooked up to it and I've double checked the brass connector on the shift linkage to make sure its right. I adjusted the shift lever as for forward as it would go and it still would not hit full forward with cable hooked up. I've put everything back to original positions. Motor shifts fine. Has anyone got a diagram on the control stup for thses old motors?

Re: How Fast ?

When you shift to forward, are you having someone turn the prop so that the shift dog goes into full engagement? I'm going out to the shop, and see if I have a cable I can measure. I can't believe that this is getting this difficult. There's going to be a loud What the.... when we find it.

Re: How Fast ?

OK, I measured a set of cables'. With both end's removed, and the core wire pushed in flush, it measures 4 1/4" protruding. In your control box, there is a anchor point for the trunnion on the control cable. In this anchor point there should be a nylon sleeve to take up any slop in the anchor point. Is this sleeve missing. If so, could you make up a shim to snug the cable up at this point. A aluminum beverage can is easy to make shims from.

Re: How Fast ?

Ok guys, I got it fixed. I found a picture of a boat with a 30 hp johnson that has the same setup and The only thing noticably different was the connector that hooks to the shift lever. It was shorter than the one I have. I went home and measured the one on the throttle and it was 1/2" shorter than the one on the shifter. I swapped the them out. I had to adjust the cable on the shifter side about two turns and everything is perfect. Everybody kept telling me all those connectors are the same but there not. Noe all I have to do is get her in the water and see what she'll do. Thanks for all your help

Re: How Fast ?

Wow! I'm amazed I didn't think of that. Old age, I guess.

I'm holding my breath to see how your rig performs out there, now that it's all working properly. I expect Zooming!

Re: How Fast ?

I had almost given up on it and was going to take it to a mechanic and pay that mind blowing hourly rate to have it fixed. The only thing is that I had taken that connector off and drove 45 miles ( I was going that way anyway) and stopped by the marina and asked the mechanic about the problem. He told me that all those connectors are the same so I don't know that he would have figured it out or not. All that behind me now I'm just ready to get it in the water.
