Port engine won't start again @help

[TheGreekTitan]

We have a verdict. Just got off the phone with the mechanic at the marina. He said it was a very strange thing, that he has not encountered before.

He did not go through all his normal steps, because I told him everything we had already done and he did not feel the need to repeat. There is apparently a "plug" on the engine. He unplugged it, and plugged it back in, and all is well. He started and stopped it at least a dozen times, then took it for a cruise where he hit waves, sped up, slowed down, etc. He wanted to see if the plug would come loose, and it did not.

I am meeting him there tomorrow so he can show me said plug. If I remember, I'll take a picture of it, because I don't believe I've read about this plug before.

On a side note: He's not sure what to charge me, with such an easy fix. I said, charge me? Isn't cruising around on my boat payment enough? We both laughed.

Charge you? Isn't it still under warranty?

Very glad you found the culprit. It's going to fall in that list that I gave you, for reasons the engine won't start. It's more than likely the other end of the switch for the clean out tray, again it blocks both ignition and the starter. But that's two switches, and that's more than likely the sensor to one of those two switches on the engine. Very surprising that it came loose, and very glad you found it without excess expense!

Yes, it is still under warranty. I don't know that he's going to charge me anything, we'll see tomorrow. He's a very nice guy, and if he does charge me anything, I'll probably just pay him. We'll see.

Makes sense to me. I guess I just missed it. After tomorrow though, I'll remember it's location for sure.

I'm glad to hear it's running again and very interested to see where this plug is at,

back on post #17 you told us the starter was "loose", how loose was it? just a slight wiggle? a 1/2 inch of play?

did you tighten it back up or give it to the dealer loose ?

 

[subysti]

OK, are you going to share said location with the rest of us?

It was a fair amount of play in the starter cable. Sorry, I was not clear in my previous post. I did not have any socket wrenches with me, so I left it as is. He did tighten it, but said it had nothing to do with my problem.

Of course. I will be meeting him there tomorrow for him to show me. If possible I will take a picture and post it.

sure he will , but he has to charge you!

Well, the mystery "plug" has been identified. It was the wiring harness at the throttle cable. Should have checked that, but we didn't.

 

[Scottintexas]

thanks for the picture, I'm not a mechanic but it seems strange to me the throttle control would be able to shut the starter down ??

maybe it has a back feed ground short shut off in the plug ??

throttle positioning sensor is a safety switch that keeps someone from starting the engine if it is not in an idle position, imagine if they did not have that, it would be pretty neat to watch as long as you were not in front of the boat,

Just to put this to bed....I spoke with the parts and service area manager today. It was covered under warranty, and he asked me to notify him personally, if it happens again. They speak to Yamaha regularly, and give them quite a bit of feedback. He told me that they have been having some problems with the 24 footers, but seldom deal with the 21's or 19's. Yamaha is about 15 minutes from my marina, so they speak with these guys regularly.
