| A guy I know in Green Bay who is over on the MuskieFIRST board (Shaun Kopke) aka "Krappie" on the board had this same issue. He had to change oil about 4 times and just keep working the engine to get it broke in. It is fine now. He worked with Heckels marine in Eagle River WI his boat is a Ranger 618, I'm sure if you called them they would be helpful.

| The problem is known as "making oil". From what I've read, the engine needs to be broken in at certain RPMs, possibly under a load, to fully seat the rings. This will give you lots of reading material:

| Please understand, I am not belittling your problem, but there is quite a history to this phenomenon.
We heard a lot of this a few years ago. A few F-115 engines actually did seem to "make oil" and these were prescribed warmer thermostats, and a few actually had a leaking fuel pump or pump gasket which allowed fule into the crankcase. The vast bulk of them were fine, but were thought to be "making oil" as a result of innacurate dipstick reading, over filling and other human error.
But, alas....once you get a rumor going like that the, pretty soon everyone who owns an internet connection is convinced the sky is falling. The rumor mill was in high gear and non-Yamaha engine dealers were loving it. They had their guys telling Yamaha F-115 owners , in forums mostly, that "their Yamaha rep. had said to take that motor right out of the box and hammer it wide open for 8 hours to break it in" and stuff like that.
But when it was all said and done, in the vast majority of cases, if you run hard after quite a long trolling day... the problem goes away. We have not heard much about this for a couple of model years. If it still does it, have your dealer check it out. The warranty is excellent on these engines and they are an extremely popular engine. |

| I got one doing it now. Purchased my boat new this summer. At 10 hours before I dumped the oil I noticed oil was way over the full mark. It was not when I bought it because the dealer pulled the stick and made a big deal about not over filling it. After the 10 hours the oil and filter was changed filled it with a little over 4 quarts ran it for about an hour checked it again on level ground it was near the full line. Took a trip after about 6 hours on that trip I noticed a strange noise when the boat was in gear just higher than idle. I had run this engine for 16 hours and never heard this before. I checked the oil it was a good 1" above the full mark and smelled strong of gas. Engine was properly broken in I purchased Yamaha software kit to monitor hours and other good things. Good luck I am very disapointed. There are plenty more posts about this and Amsoil has a document on the lack of burn off. If that really is where this gas is coming from I don't know.

| Have your dealer check it and document it. But at 16 hours, the rings aren't seated on quite a few of them. If you changed to Amzoil back at 10 hours, you might want to back to oil for a couple more changes so the rings have a better chance to seat. Excellent viscosity in Amzoil, and maybe too much for rings to get seated good.
We had one F-115 that did this for a whole summer. It was a 2000 model. It finally straightened out after we ran a strong dose of ring-free in several tanks. We took it out and ran it hard, and then had him run it hard. Luckily, he had the free time and didn't mind doing it. That fellow did a lot of trolling and not much running which may possibly have been a factor. It has been working excellent since.
I believe we had a Yamaha Tech update somewhere along the line a couple years back that called for putting in a warmer thermostat in the F-115s...but that was a couple models years ago.
When you change the oil on that particular engine be sure to tilt it all the way up, pause 10-15 seconds and then down again, after oil initially quits running out...usually more will come out after you do the tilt thing.
By and large, these have been excellent and trouble free engines. |

| Thanks for the replys guys. I took it into the dealer and Yamaha changed the ECU, and put in hotter thermostats and plugs. Even though it was out of warranty (01 model) I just hope no permanent damage was done. with the hard water season coming up fast it will probably be next year before I find out. By the way, there was definitely gas in the oil, not just overfilled. I took a sample and sent it in for analysis just in case Yamaha gave me a hard time, which they didn't.
Thanks, Scott |

Location: Midland, MI 48642 | My neighbor has been going through the same problem with his yamaha f115. He is working with the dealer, reps, and the company. Make sure you get everything on paper and don't let up. If things aren't normal with this warranty goes out its going to be a court case. If your ever interested in talking to him you can send me a private message. Its no little problem. Skeeter |

| Jerkin,
After this engine gets enough time on it so that the rings are seated, switch to a Fram or some other oil filter that has an anti-syphon valve on it.
The yamaha (Denso brand) filters don't have this feature and it gives us techs fits.
Rings being seated (being broke-in) and using an accurate amount of oil, is the deal. With a filter that holds oil, you eliminate the guess work for the amount in the crankcase. |

| I am getting ready to sue my Yamaha dealer for selling me a F115 2005 Engine
that had 24 hours on it when he sold it for brand new.
I have had nothing but problems.
The hour meter says 42 hours, the black box on the engine says 66 hours.
The engine oil looks like tar |
