SHO's "making oil" questions..looking for some answers

[rb]

Folks I don't own one of the engines, but I want to try and gather some info. Before I was laid off in Jan I was the complaint manager of North America for a medical device company. When we had a complaint it was very helpful to get as much info as possible on the problem. Here is a list that if everyone who is having the "making oil" issue can provide, it may help find a solution. Again I own an old Mercury, but I hate to see guys get upset and not be able to enjoy their time on the water. Trust me, after not being able to afford to go for 9 months, ITS KILLING ME
SN# of engine
Hours on engine
What boat is engine on
What prop are you running
Do you run a jackplate if so what type
What additives are you putting in fuel tank i.e Stabil, Seafoam etc
What octane fuel are you using
When did problem start:I can't recall these starting until hot weather

If you think of anything else list them. Hope it gets resolved guys.

I'll play along. I am curious if this is occurring more with one HP versus another, so this will be helpful.

Boat was new in April, 2010 Problem was found within a few months of purchase during the 20 hour service.
My strategy, let Yamaha make it right like they always have.

i follewed the break in to the letter. i was out there for the first crtical 3 hours with the stop watch and the owners manual. the next 7 i spent just like they said to.

my first symptoms came in hour 6 when the engine started to smoke at idle. a check revealed that the level rose from halfway between the marks to an inch over full. i took it to the dealer for a change and a download. the next 30 gallons of gas rose the level from between the marks to full. this time the dealer took an oil sample for yamaha. i then changed the oil and filter again on my own. the last two 30 gallon days saw only a 1/4" rise each from the center on the stick. i am in hour 10 now and the oil making is subsiding significantly.

Another question would be how much oil are you draining? Is anyone measuring?

[gasbasser]

They drained 9 quarts out at the 20 hour service. The dealer pulled another 1/2 quart less than a month later. I have pulled a quart off 2 other times since last July. I have also had the oil changed twice since purchased in April of 2010.

... i change the entire batch and filter every time i get to full on the dipstick.... not taking any chances. from what i can gather reading all the other information is that an inch on the dipstick is about a quart or so.
