milky water coming out exaust at prop

[phatmanmike]

what could be causing this, motor is 1972 electric shift 50hp 2cylinder. spark is good on both cyl, compression is 160 on both an d carbs were just cleaned by me by taking off motor and taking apart. runs good and starts and idles, but im concerned about white milky exhaust...motor was sitting for about a year . i picked it up off ebay!<br /><br />thanks<br /><br />mike

It's just unburned oil mixing with the exhaust water. Very common and nothing to worry about. BTW, you know those electric shifts use a special gear oil, don't you? Good luck with your motor.

check for over rich fuel mix, fouled plugs or weak coil or ign components but some of it was normal. some motors did more of it than others. its unburned fuel mixing with water.

Re: milky water coming out exaust at prop

i like your post, rod bolt.. i was thinking that maybe it was missfiring on #1 cylinder sometimes, but wasnt sure.. that would explain it maybe

weak coil or ign components

its unburned fuel mixing with water. <br />

just to let you know, this is coming out WHILE its running, not dripping out afterwards.. i shoulda said that first

check to see if theres water in your gas tank, even if its new' gas, some stations can get water in there tanks, it happens quite often around here.

Was this thing fogged before it was stored? My engines always have that milky crap coming out of the prop after I first start up in the spring, it's the fogging oil mixing with the water, I would keep running it in the driveway and see if it goes away. Good luck.
