Hey RT, Hey Ross,

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

Maybe he did, but it didn't run for very long.
The usual protocol for changing the oil and filter requires running long enough to fill the filter before checking fill level to make sure the engine has the right amount of oil, so it should have at least been run 5 minutes and all oil passages that had the cafe au lait would get that replaced with new oil. The dipstick should then give you a good indication of what is in all of the oil passages.
From now till you get the analysis won't make a significant amount of difference, so I would wait and look for either antifreeze or salt water in the report. Once you know that, you are closer to knowing the source and can plan your next step.

Thanks Keith. As I said, the oil analysis reported a high amount of H2O, but no glycol. And my boat has always been a fresh-water vessel.


I'm confident that, since it's standard procedure, the techie ran the genny for awhile after installing the new oil and filter. Nevertheless, I plan a drive up to have a peek at the oil again myself.

Greetings,
Mr. RW. Some people may not know where Oakville is much less Ontario or Canada...







Present company excepted, of course!

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!

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.

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. :-)

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.

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?

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...3e845c99206584

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.

No dragon until just before you drop off at the end of the world near the rim of fire.

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.
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?
