probly a stupid question

[billbass9]

i dont know much about outboards so i was wondering is there a oil window dipstick or level plug on the block of the motor or does it use oil from the bottom (gear drive)? i cant find a oil dipstick and i know that a 2 stroke u mix the oil in the gas for the rings but dosent the crank still need oil or not? please help its driveing me crazy i cant stop thinking about this motor i need to be schooled

No oil sump, no dipstick. Everything gets lubed from the fuel/oil mixture

Don't worry bout a thing.That's y we post here.Your 2 stroke gets lubrication from the oil mixed with the gas,or injected otherwise.Because a two stroke (most of them) pulls the gas/oil into the crankcase first,then boosts it to the top,the crank actually gets gas/oil first.<br />DHP

The charge (fuel/oil/air mix) passes through the crankcase on it's way to the combustion chamber, so it gets lubricated then. Also, in most outboards everything in the crankcase is antifriction - there will be roller and ball bearings on the connecting rod and crank main bearings. These don't need as much oil as a plain bearing in an automobile does.<br /><br />The reason the charge passes through the crankcase is that each piston's crankcase chamber (they're isolated from one another) is used to pump the charge into the combustion chamber.<br /><br />Here's a good article - <br />How Stuff Works - 2-stroke engines.
