OK - so maybe it's a newbie’s assumption gone wrong....after not more than 12 running hours, total, over this season, the brand new Merc 4 cycle, 8 HP ran low on oil, while fighting a head wind back to port. The Merc has a low-oil safety feature which drops the allowable rpms to about 1/4 speed (we had been at 3/4) and we crawled back home, at times barely able to overcome head gusts. ANYWAY, who knew? I expected the oil level would need to be checked occasionally, but clearly, it's now part of the routine before going out. Which is too bad, as the dip stick is awkward to get at, and the filler is nearly IMPOSSIBLE to reach from the cockpit...who knew...

Jerry,
It could be the new engine burned some oil while the rings set but I would not expect a new 4 cycle engine to burn any perceptible oil in 12 hours of operation. I would report it to who ever you bought the engine from in case it becomes an ongoing problem and requires warranty work. I believe the crankcase holds less then a quart so it doesn't take a lot for them to get low.

Hi Jerry,

I agree with Joe. You shouldn't be seeing any appreciable oil usage with your new engine. I have a Merc 9.9 electric start on Snickerdoodle which I purchased in April 2005. There's been very little oil consumption at all.

If your engine continues to use oil, take it in for a check up -- something's not right with the engine.

If it were an air cooled motor, you might see oil lose in a new engine because the tolerances are much greater, but in a new water cooled motor it is eight broken or seating in. In eighter case I would bring it to the attention of the store you bought it from. Cheers.

Joe,

I Would have the engine checked ASAP. Also,I would NOT run the engine any further untill it is inspected.
I have a brand new tohatsu 4-stroke and I have never had to put a drop of oil in inbetween oil changes.

You might just find that you have a severe problem or maybe just a lose drain plug, but eithe way having it checked ensures that if there is a failure your warranty will cover it!

Just my two cents
:D

Jerry/Adam,

There was a post(several posts) earlier in the season speaking to this problem. It turned out that the motor had a factory defect gasket the was later corrected. I'm not sure but it was either Pam or Cate. Check their posts in SEARCH and get the facts. I could be wrong.
