I searched for info on my problem, but I just couldn't find anyone with the same problem.

Background on the problem: The ignition switch for my engine is installed within the main switch panel for the boat. the ignition switch is held in place on the main switch panel with a large nut that screws into the threads on the outside of the ignition switch cylinder. Under normal operation, the ignition cylinder would rotate within this nut while the nut would remain stationary. For the past several weeks, I have noticed that I need to turn the key 120-180 degrees to get the engine to crank instead of the usual 30-45 degrees. I has also taken a few cranks to start the engine instead of the usual one crank. All this time, I just thought the outside nut was a little loose so I wasn't that worried about it. Just tighten the nut & everything will be ok.

So yesterday, I decide to get up underneath the console & tighten the nut down really well. I go to start the engine, and the key will not turn in the ignition lock. I have the safety switch installed, the right key, and the boat is in neutral. I also remembered in the past few weeks that the ignition switch was not requiring two clicks of the key to crank the engine. I usually have to click over to the "run" position, then click over one more time to the "start" position to get it to start. But in the last few weeks, there has been no "run" position. Does anyone have some insight as to what is causing this problem?

The engine runs flawlessly, I just can't turn the ignition to start it. I think the ignition switch was starting to lock up in the past few weeks & that is why the retaining nut was getting loose. The ignition switch was locked, then I kept turning it, which caused the nut to become loose. I also think the ignition switch was having a harder time getting a good connection, so thats why it was starting to take multiple cranks to start.

So is there anything I can do to save this ignition switch, or am I going to have to buy a new one?

Thanks in advance!

I had something simular, the threaded part of the ignation switch had broken on the swicth. Look in behind the twin switchs and see if it is broken. Or unscrew the nut from the front of the panel and look that way.

Thanks for the replies guys! Does anyone know what the part number for the ignition switch I need? I just need the single switch. How hard is it to change the switch out? I called the yamaha dealer & they said that it was pretty much just "plug & play." I looked at all the wiring, and there are 2 (black & white) wires going from the ignition switch to the safety switch, then the rest of the bundle of wires heads towards the plug. My question is, there are some wires that are spliced off of the bundle near the plug and they go off to what either looks like my rpm gauge or my throttle, where do these wires head & is there another plug-in over there?

Also what all comes with the ignition switch when you order it? Does it come with that safety switch connected? The yamaha dealer quoted me $170 for the switch & 2 new keys.

Sorry for all the questions...


Thanks,
Ben

dunno, there are several different switch panels it could have been rigged with.
if its all factory YAMAHA branded rigging it should be plug and play.
depends on how many shop monkeys have played with it.
