Winter storage without oil
Hello folks,
Time to winterize is coming soon for me and it brings me a question.
Would there be any issue to keep the boat without oil in the pan for winter?
As soon as the boat is out of water I plan to make some maintenance like changing all oil hoses, water hoses and rebuilt support for the oil coolers.
As this will require me to remove oil first I was wondering if there would be any negative effect to keep oil pan empty and refill only before going back to water next spring.
Any input will be appreciated.
Thank you!

The only negative I can think of is forgetting its empty and starting her up! Otherwise, no.

Sorry, I'm a newcomer here and don't have any bona fides, but I would advise against it. First, when you change the oil you let it run enough to circulate the new oil through the engine. I have to believe that displaces much of the old oil along with many of the contaminants. This would leave a nice coating of oil on the internal components.
Otherwise, simply draining the oil (or leaving the old oil in the engine) would leave all of the old oil on the surface parts. I can't help but feel that's a bad idea (although I confess I have no particular expertise to back up my feeling).

I believe that the old advice to store an engine for the winter with new oil has been outdated by the switch to ultra low sulfur oil.
So, no technical problem with draining the oil pan, but I would put a tag on the starter switch to that effect. You never know what might happen to you and who might start the engine next spring.

I’m not sure why your thinking that you need to drain all the oil to do those items.
I would change my oil, run the engine then winterize. You’ll probably lose a quart or so in the process of your planned maintenance. But you will have the piece of mind that your engine is well protected for the winter with clean oil. Plus you get the benefit of wiping up relatively clean oil after those two drops hit the bilge.
I just changed out my coolers and hoses and lost very little oil..... blood on the other hand....... gawd do I hate hose clamps!!!!!

I really don't think it makes any difference, old or new. Dino oil drains away leaving virtually no oil on anything, basically dry.

Why is the engine well-protected with new oil over the winter? It all drains off into the sump leaving virtually all parts with no residual coating.

Not sure why any of this requires removing oil. Oil will drain to lowest point which is the engine oil pan. Any leftover in the coolers will remain there whether you drain the oil from the pan or not.

I doubt if it makes any difference at all. But do what you feel is right.

Drain away, only downside is forgetting.

So, for those who are saying there is not residual oil on any parts, what do you consider residual?
Take off your cam cover and rub your nice clean white shirt on all the surfaces.
Post the picture showing no "residual" oil.

The usual procedure drain while hot , refill and restart leaves the oil pump full of oil.
In the spring the oil pump , even submerged in the pan may take longer to fill with cold oil and create pressure to lube and spray inside the engine.
Synthetic drains off more than regular oils , and perhaps straight weight might leave more on the cylinder walls than thinner multi grade?

A good test I suppose but don't wipe alĺ surfaces, just the vertically-oriented surfaces. Here's a question: why is it that, supposedly, 90% of engine wear comes from engine start-ups? Might it be because the lube oil has drained away? Methinks so. By the way, the chemical properties of synthetic oil are such that it leaves a residual film. Do a simple test. Take two socket wrenches. Coat one in your preferred dino oil and one in a synthetic diesel oil. Cover to simulate a valve cover. Come back in a month and let us know the results. I am doing the Loop right now or I would do it myself.
Here's another BTW. I just received the results of an oil analysis after 343 hours of use on a synthetic oil. Second time tested. Testing facility recommended continued use, again. TBN was almost eight (8), viscosity spot-on, soot levels within parameter, same as in the first test. Diesel oil TBN generally starts at twelve (12). Oil is still doing it's acidity mitigation with TBN levels as low as two (2) but I think oil analysis houses would recommend changing the oil at about four (4) TBN.
I changed the oil filter after the first test. However, I did go ahead and change the oil before having received the results of the second test because we were laid up in Charlevoix, Michigan for six (6) days due to high winds on Lake Michigan so I had time on my hands. My engines are Lehman 120s.
As far as basing oil changes on test results, our military does that as do many managers of large fleets of vehicles. Large fleets and large vehicles with large engines use lots of oil and there is a labor cost as well. Why throw away oil that is still able to do its job? Soot load? No. That is tested. Change the filter and go boating.

Just the opposite. Synthetic stays, dino goes. It's the chemistry of synthetics that makes it cling. The molecules are all structurally the same which causes it to cling to surfaces. Do a little research and you will discover that you assumption is incorrect.

Some intentionally designed additives in quality diesel oil provide a cling factor. Or so says the advertising stuff like " Isothyn Technology" or lube oil forums (yes, they do exist) postings. If it were not for starts and stops our lightly used diesels may well rival shore based gensets for longevity.
But as Tony Athens has said many times, he has not seen a diesel wear out due to oil breakdown. His mantra is correct propping and maintain the seawater side. I believe him.

"Just the opposite. Synthetic stays, dino goes."
There are varying opinions , but that's where DA Book (the shop manual) for your engine comes in.
Detroit prefers special preserving oils for long term periods of out of service.
They sell preserving oil , but the simplest can be a local airport , where piston engines are found.

"But as Tony Athens has said many times, he has not seen a diesel wear out due to oil breakdown."
Breakdown is not the problem , rusting and pitting of cylinders in storage causes lower compression and white smoke , even with a warm engine.

When you put the oil back in it in the spring, just pull the lead to the shut-off solenoid and use the starter until you get oil pressure. Stop, reconnect, fire away.
Leaving your engine empty for 6 months won't hurt a thing. Rusting and pitting? Maybe in a long time but pretty much every boat out here stays in the water, is shut off in the Fall and is not started again until Spring. In fact its better to NOT start them because they will not warm up properly without a load.

Excuse my caution but I have seen or heard of almost every crazy thing happening in boat yards so my suggestion is a sign on the helm in both English and French that the engine lacks oil and is not to be started under any circumstance. If possible remove the key.
This is especially true if you are having any work done on the boat during the winter.

For SURE I will put a sign saying DO NOT START if I choose to leave it empty of oil. I did the same last spring when I disconnected coolant hoses. Knowing the clowns working at my marina I do not take any risk anymore
