Would you beleive this motor ran just fine (pics)

[rajawolf]

Here are a few pics of a outboard motor that purred like a kitten.....pulled it down due to pressure in a cyclinder being very low :o

Also shows lack of flushing..cause the kids said they flushed it.... :-/ after using it for water sports ;D

pic 1 ...piston ring stamping.

pic2...top of bore stamped.

pic3... lot of salt.

pic4 ..same salted..

Think this is a great example of why outboards used on a regular basis
seem to go for ever vs ones that sit for a while go to the dogs

Damage in the first two pics looks more like a needle roller got in there (probably from a small end bearing). #Ouch.

Might be easier to fix than the corrosion though.

Amazing how they can still run like that.

My oldman once told me that 99.9% of time the reason motors don't work is electrical.

It is amazing how much tolerance machined parts can have (or even be cracked and broken) and the engine still works.

I wouldn't worry about that corrosion too much #;) just don't go out to sea with it :-)

Keep the photos coming I always love to see other peoples jobs and heart aches.

The fact it kept running with that floating around the top is just plain good luck ;)

Haven't kissed a Chinaman for good luck lately have you Tony?????

Rhys,
No mate..well maybe...I bought the boat off a friend, knew it would have problems..but got the 5.2 metre boat,motor, trailer plus extras for $1000...all been fixed and on the water again....but I cant catch any fish :-/

Soon as i can reduce another pic... i will post a pic of the boat ect ect.

PS... that stamping on the piston was caused by the top ring tearing out of the piston, it only rattled for a second and spat out the bits. Just a slight hiccup;D

It's when you see that sort of thing you appreciate how many times that piston is going up and down in a second.
Back in my racing days I dropped a valve in my Kawasaki 1000 at about 10,000 rpm.
Heard the noise, pulled in the clutch and hit the kill switch all in probably 1/2 second or less.
Didn't think it'd be too bad until I dropped the carbs and the valve head fell out with them.
Couldn't even ue the piston for an ash tray ;D

cheers,
Owen
