Yamaha 115 4 stroke stalling

[Northlander]

When I put my boat in nuetral my motor stalls. Do you mechanical guys think its a throttle control sensor or what else could it be?

Oh and its a 03.

Steve -

Any other signs / symptoms? Does it idle while in gear and only kills when you shift to neutral?

Does it shift to neutral then die, or does it die while you're shifting into neutral?

I also have an 03 and it has also done this a couple of times. It always starts immediatly afterwards but it has made me wonder a little. I would also appreciate any help. Thanks in advance.

If I come to a dock and shift out of gear into the neutral position it stalls almost every time now. It runs perfect besides this problem. I know this motor had some sensor replaced a year before I got it. I have also heard the 02 and 03's had this problem frequently. Im just wondering if RPM's are getting too low in neutral or what it is.

Its going in next week but I want to make sure I sound like I know what Im talking about.

Steve, have them check neutral switch. Sometimes shifting linkage goes out of adjustment and engage the "gear start shutoff switch", which is the device that doesn't let motor start when in gear.

Many times fuel problems were addressed but those weren't the problem.

Since it's in the shop as might as well have them check it.

[Northlander]

Thanks Valv Ill have them check that too.

northlander,

I have an 01 f-115, same thing. When I first bought the boat it idled a little high, but I never had this problem, I brought the boat in for the higher idle, they adjusted it down, since then it will stall when engauging it into nuetral. I figured I would trade the stalling once in a while, ( half of the time) for a couple hundred rpm lower for trolling. I would rather it stall a few times then having it idle higher. But if you find out a fix for yours, other then raising the rpm up, let me know, I will bring mine in to get fixed also!

[Northlander]

Ya I dont want higher RPM's either. Mine trolls pretty nicely for a 115.

[marine_man]

Tough to say Steve... I'm thinking it's got to be along the lines of Valv's suggestion if it doesn't die while in gear and low idle. I presume it's a quick shutdown and not a slow shutdown, like it looses spark, right?

Ya as soon as I hit neutral its stalls out. I just had it tuned up and it runs great besides that. Some sort of sensor was replaced 3 years ago and it worked fine til last fall.
