Hey RT, Hey Ross,
Sorry....the fact that it is a freshwater boat fell out of my mind somewhere along the thread!

Actually, RTF, the mechanic did replace the oil and filter same day as we discovered the cafe oil. And the service manager recommended having the oil tested (at a cost of $99), which I thence ordered. I just don't recall if he started the genny immediately afterward. Maybe he did, but it didn't run for very long.

Ontario??? What's that?Greetings,
Mr. RW. Some people may not know where Oakville is much less Ontario or Canada...
Present company excepted, of course!
Sadly, you're probably correct, RT. But all you 'south-of-49ers' should consider boating our pristine waterways. People come from around the world to travel Georgian Bay and the North Channel.Greetings,

Thanks, Greg, for your comment. The boat has spent every winter in heated storage. So, though I've not tested it, I'd not expect any glycol in the cooling system.Hey Ross,
Out of curiosity, is there glycol in your freshwater loop? Its absence in the oil, given the presence of large amounts of water, could still be a clue as to the source.
Cheers!

Sorry FF, but I don't follow your proposal. I presume you mean a spark plug low in the engine? But how could 'hosing down the dipstick hole' remove water?IF the oil is removed from the engine with a low point plug , a couple of changes will help .
I would use a hand pump and hose down the dip stick hole to remove the water in the very bottom of the pan.

No dragon until just before you drop off at the end of the world near the rim of fire.Georgian Bay, isn't there a water dragon lives?
I understand. Thanks ski.Many of these little engines the drain hose comes out of the side of the oil pan, which really does not get all the water sitting in the bottom. On some a little sucker tube can hit the bottom of the pan and then you get almost all of it out.
That's what FF was referring to.
Also look in the oil fill hole in the rocker cover and see if there is moisture beaded up on the rocker arms and springs. That is no bueno.
And it's still beautiful, Rich.Boy oh boy are you right about Georgian Bay beauty!!! 1992 was a great year there.
Anytime I found milky oil it was standard practice to drain, fill with diesel, drain and add new oil and filter. Any decent mechanic should have a way to pressure test the fresh water side. How old is the riser?Yea, you don't want that engine sitting over the winter with water in it. Good chance you will be buying an engine in the spring.
What generator model/brand?
I'd get the yard to back the boat out of the shed to where you can do a proper job of drying out the engine running it loaded on garden hose.
If that is too much trouble, might be able to fill whole engine with oil or diesel. Maybe take rocker cover off and dry out that area, that's where condensation tends to collect.

I agree that it should be possible for a mechanic to perform such a task. Perhaps it would be challenging since the boat is in the back corner of a very large heated building - with numerous other big boats on blocks surrounding her. I plan to drive up and investigate further, now that I have a better idea of what I'm talking about, thanks to everyone here.Anytime I found milky oil it was standard practice to drain, fill with diesel, drain and add new oil and filter.

Not sure, Greg, but I believe the Kohler 8kn diesel generator has a closed cooling system with heat exchanger. I know the main Yanmar engines are configured this way. But the Kohler?Hey Ross,
The boat has a closed freshwater loop and heat exchanger?
I know water has a higher specific heat capacity than antifreeze (ethylene and propylene glycol), so it cools better. But, even in Florida (and So Cal before), I've always used an anti-freeze/water mix. I guess I figured there'd be anti-corrosion and pH-balance additives that would help keep the cooling loop clean and corrosion-free.
I'm not saying what I do is right, or that you should do it, too. It is just what I was taught to do -- and sort of thought everyone did.
Greetings,
Mr. OD. I've never heard of any "creatures" in Georgian Bay although I am not very familiar with Lake Huron lore. You may be thinking of the Ogopogo that dwells in lake Okanagan in British Columbia.
Here's "proof"! https://www.news.com.au/technology/...s/news-story/c81bf6fd15b59a2e4e3e845c99206584
Thanks, James. That practice sounds, well, sound. In theory, though, stowing my boat in a heated building for the winter should alleviate me of the need to fully winterize my engines. I'm told that all I have to treat is the septic and fresh water systems, that is empty and shock them. Is this not your view too?Ross,
I’ve been boating (and winterizing) on Georgian Bay for a number of years. Once our boat is hauled, I run the generator with a winterization kit connected and fed into the raw water strainer.
https://www.amazon.ca/Camco-65501-Yourself-Boat-Winterizer/dp/B0000AXQU2
I fill the 20 ltr jug with pink RV antifreeze and the start the engine. Open the boiler valve on the jug and it’s fed through the raw water circuit. It will run for 2 or 3 minutes on 20 ltrs.
This would allow you to run the engine without the need for a water supply in the storage facility. You could then change the oil and filter one more time for peace of mind over the winter. If the yard won’t allow you to run it yourself, get them to do it.
I winterize both my main engines and the generator this way every year. Not ideal for oil change as the generator doesn’t get hot, but at least you’ll have the peace of mind knowing there is a second change with fresh oil in it for the winter.

That makes sense, Keith. I plan a trip up to visit the marina very soon to investigate further.https://youtu.be/85hoQeXLmVw?t=14
Seems our Lake Okanagan Ogopogo has a sibling in the desert.
Seriously though,
I have never seen any engine filled with just water. Manufacturers ALWAYS put in a 50% mix of Anti Freeze and water, as there are corrosion inhibitors in the AF. Your test results showing no AF now prove that your milky oil is from a water leak, so look at exhaust riser, water pump seals, Oil cooler leaks, but not at Head Gasket or other sources connected to the in-engine cooling.
My boat is equipped with an oil extraction system. Thus, most of the oil can be removed easily. But perhaps the remnants of the oil, and water, if any at the bottom of the pan, could be removed using a hand pump. I'll put it into practice. Thanks Tom.The idea of extracting most of the oil/water through the dipstick using a hand "oil" pump and small hose is a good one as the water will eventually settle to the bottom. That should help remove the water as long as you don't still have a "leak".
Otherwise, great advice to change the oil and filter a few times to "clean it out".
