Customer: The throttle cable on my boat was replaced in the fall of 2013. I just put the boat in the water and the throttle went up but when I tried to bring it back down it was stuck in the up position. Then I put it in neutral and it was idling extremely high. Now the engine isn't turning over. Is there an adjustment I can make to the throttle cable to fix this?

Hello. My name is***** will be assisting you. There is ab adjustment. Go to where the cables connect to the engine. On the control cables is a knob that can be turned to get the adjustment setting correct. In this diagram the red arrow points to the knob. Turn the knob clockwise to get idle down. This should also move the warm up lever down. Make small adjustments and test till you get it set right. Post back if this doesn't work.This pic may not look exactly like yours but the idea is the same.
What if the throttle cable isn't moving at the front control box when moving it forward and backwards. I'm watching it as I move the throttle forward and back and the cable doesn't seem to be moving. Also, is there a chance that any of this would prevent the engine from starting?
Then there is an issue with the cable or the control box itself. Yes if the control box has an issue the neutral safety switch could be activated not allowing the engine to crank. The control box needs to be opened up and inspected for an issue. Is the a Evinrude side mount control box?
There are certain parts that break in these control boxes. # ***** and # ***** The idle is affected by the # ***** which affects all the alignment of the gears and the warm up lever. The # ***** will affect the shift causing possible engagement of the neutral safety switch. So the control box is where we need to start. Does the shift lever move back and forth smoothly or is it difficult? Is the warm up lever # ***** sloppy?
Do the rubber screws on the top and back of the control box control anything?
The lever moves back and forth smooth. When I put the boat in it moved forward to increase the throttle but never came back down with it. It seems stuck in one place now.
They do throttle friction. But they won't have anything to do with your problem. The lever moving up is the throttle cable adjustment. Will the engine go in and out of gear? Just have some one spin the prop when you shift the control. The prop should lock in forward and reverse and spin free in neutral.
Yes, the engine went into reverse, then forward for a spin around the lake, when I was pulling into the dock I was trying to throttle down but it wouldn't. It was stuck where I had increased it to. Then I put it into neutral and it was at a high rpm making a loud noise. I killed it, and looked at the throttle cable and it wasn't moving with the lever. The lever is moving fine, it's going in and out of gear, but the throttle cable isn't moving. Should I open up the box and make sure it's connected to the lever?
Ok when you push the shift lever to full forward then down further giving throttle is the throttle cable moving? Is the warm up lever sloppy?
The throttle cable is not moving. I don't know what the warm up lever is.
Ok disconnect the throttle cable from the engine. Grab the cable end and pull on the end how far does it move? The warm up lever is the lever on top of the control that you pull up to warm up the engine.
Tan, you've been great at answering questions. I'm actually not at the boat right now and won't be until Friday evening. It's at my Dad's lake house and I have a bunch of friends coming for Memorial Day Weekend. I'm hoping that from this conversation I'll be able to figure out what's wrong with it. If there's anything else you can think of that might be the problem, I'd appreciate your help. I will try everything that we talked about here and if I disconnect the cable from the engine, grab the cable end and pull it, what should happen? I'm thinking that it should move, but what if it doesn't?
Your welcome..........The cable end shouldn't move any. If it does then the cable is broken internally or not connected in the control box. The only way the throttle cable should move is when the throttle lever is pushed forward and backward. If the warm up lever is real sloppy it has come loose inside the control box creating an issue. Now you can post back with findings and we can try to get this figured out.
Great, I'll be working on the boat this Friday and I'll send back any questions. Thanks again.
Ok your welcome........Thank you.......Tan
