just picked up an old kawasaki 550 jet ski, on the front of the motor is a black screw in plug. what goes in here, if anything, I unscrewed it, and it is dry inside. thanks for the help...

It could possibly be a garden hose hook up to flush the motor(?). OnlineMicrofiche Index has schematic drawings of your motor. Just pick the make/model/year and you can see the schematic of what (if anything) goes there. There will be an associated part number as well.

here is some pics of the plug, it screws in the case in front of the motor, there is nothing inside, water, oil, nothing....what is it for please...

That's a crankcase breather. You can google what it does, but it's mainly to ventilate air. There shouldn't be any water or oil in it -- which is a good thing. There should have been a picture of it on that website under the crankcase section.

crankcase vent

hey thanks, didnt see on the website, but may have overlooked it

you're welcome. Happy and safe boating to you.

 

[no fear here]

That is for checking the ignition timing. It should be dry inside. No water or oil ever!!!
