Author Topic:   Replaced throttle cables- now boat won't start

Yesterday I replaced the throttle cables on my 89 montauk. It has a 90hp Johnson and the original OMC throttle arm. The throttle is now real smooth, but now the engine won't start. Battery is charged, connections to the battery are intact, and no connections are loose where the ignition is. prop spins easily in neutral. When you turn the key all the other electronics on the boat turn on except the motor. It doesn't make even the smallest sound. Does anyone have any ideas where the problem might be? Where is the sensor that won't let the engine turn over unless it is in neutral. Does this need to be adjusted or recalibrated if the cables are replaced?

The sensor on my '97ish Evinrude is in the
throttle. Yes, it may need to be recalibrated. On mine, it looks like the
two wires to it are yellow with a red stripe.

that is correct trib. yellow with a red tracer. use a jumper lead to bridge the two wires and try to start your outboard. if you still get nothing you might check the small fuse on the engine wiring harness. its a little bugger about a 1/2in long. replace it with the recomended one, steve out.

Check your KILL switch. Maybe it fell out while you were working on the cables.

It sounds like your nuetral safety switch.It is a small microswith inside the controls over by the cables.It must be in the notch of the cam in nuetral.

Just a suggestion, whenever I have to do repairs/maintenance to my motor, I go to the library and check out the repair manuals. They have helped me with details such as torque settings and adjustments.

Thank you for all the helpful replies. Unfortunatley I have still not figured it out. I replaced the battery as the charge has been a little low lately and I was going to do it this summer anyway- No improvement. I found the little switch in the throttle- it is in the little notch as it should be when in neutral. I traced every piece of wiring in the ignition back to the engine and can find no loose connections or wires out of place. Today I did stop by the local library and picked up the clymer guide - it's time to play with the voltmeter tomorrow. If I can't figure it out tomorrow, it may be time to drop it off at the mechanic. I love my boat but sometimes...... Again, thanks for the help-

ps. Are there any fuses back on the engine itself?

I presume you mean your starter won't turn the engine over. There is a main fuse in the engine proper. Unfortunately, I'm in New Jersey and my boat and my repair manual are in Florida so I can't be more specific as to location. It's an inline fuse. If my recollection serves me right it is in the vicinity of the starter motor and solenoid. I've had it happen to me. If this fuse fails the starter circuit is dead.
