Don't want to steal thread... But this is a quick question.
Should my 115 Yammie Saltwater 2stroke idle with a little bit of a vibration every second or so? It's just that you guys appear to be saying it should all be silky smooth. (if I understand you correctly..)
Mine is only 45 hours old.
Walruslike, the thread is discussing issues with a 200hp Evinrude FICHT motor, so NO, no one is saying your Yammie 115 will idle smooth.
From my experience around Yammie 2 strokers, NO. Your motor will NOT idle smooth with no vibration, itll idle like its about to shake itself to bits. LOL ALL Yammie 2 strokes Ive seen, idle a bit lumpy but smooth out at higher power.
Sorry the noise, smoke, rough as guts idle and high fuel consumption, you will just have to live with.
LOVE my Etec115, none of the above issues with it.
checked my plugs today and they are all very oily and all had a bit of carbon on them..
I started the motor on the muffs and waited to the motor warmed up and started pulling plugs, The motor ran with no vibration but a little rough... anyway I pulled each plug lead off and the motor changed note for a split second and then smoothed out again, so to me all plugs/pots are firing OK... I then started looking around the motor and the only thing I could find was a bit of fuel/oil around the front of the motor below the intake as if the motor had been flooded or running very rich (just a guess)
I rang Wynnum Marine and its booked in for Wednesday, I had a bit of a chat and he said they will do some testes and will give me a written report and call when they find the issue. But he did say it sounds like the motor is running to rich..
I will let you all know what they find.
Cheers

Wynnum Marine are doing what with your testes?Originally Posted by fishfeeder
Don't want to sound unappreciative or anything mate but you can probably keep the results and the report to yourself.
He's having them marinised. In winter water they won't jump up into his throat so much when the cold water hits them.
The operation is called a 'balls up'.
Around the intakes there is no fuel as such ( only injected at the head) and the only thing there is the fuel hoses, low pressure fuel pump and the vapour separator. Vap sep is is a needle and seat affair and they do have some issues especially if they are getting airated fuel from a leaking fuel hose stuffed fuel pump. Only othe rthing there is teh fuel filter if it wasn;t screwed on tightly or has a damaged seal may leak.
Good news that all pots were fueled and firing
OK, dropped the boat off today for Wynnum marine to go over...
They couldn't find anything wrong with it after checking everything.
Checked the engine computer and No errors,
Checked the engine temp and its fine (60 degrees)
Checked the Cyl Drop test (?) and said no problems there.
Checked the exhaust to make sure it wasn't clogged and all clear.
Checked the plugs and fine.....
So maybe I am just stressing about nothing !!
Oh and they only charged me $100 for there time, which I am happy to pay for peace of mind..

so then, all good to go for 1770? Was talking to Pete this morning, and all seems good.
Bring on 1770 I say, I might have a seat on the boat for yourself and son for a few days, if the mate can't get the weekends off work...
Will let you know soon
Cheers

I have owned two 115 v4's. When out of the water and no backpressure there is some roughness particularly cold. In the water they idle smoothly and particularly in gear.at.idle they are very smooth. I will have to remember to.take a.video. cheers
