Anyone know how to avoid messy oil filter change on GT40?

Re: RE: Re: RE: Oil filter change

I also use a plastic bag with minimal mess. I don't drain overnight. Kinda pointless if you ask me. Do you guys that drain overnight, drain overnight in your cars too?

I would if it had to drain through six feet of small ID rubber hose with a 90 degree bend in it.

I think that letting it drain overnight is a little extreme, but it certainly isn't going to hurt anything. If you have the time and determination, why not? Daniel has 2200+ hours on his boat and probably due in large part to how well he takes care of his boat and engine.
I am unable to drain either one of my boats through the plug, so I cannot even try it to see if that much more would come out. I have to use a suction pump. I am pulling the 289 at the end of the season and am going to drain it on a stand. I will stick a pan under it after everything is seemingly drained, and see what more comes.

I do not think the overnight oil change is extreme, it is easier.
I have a small handheld pump that I can just plug the oil drain hose into, and when it it time to change the oil, I take it, and 4 empty quart oil bottles from the last oil change to the river with me, and a 9/16. and a 5/8 wrench.
While the other people are wiping down the outside of the boat, pull the oil drain hose out, remove the cap, and suck the oil out with the pump, and into the empty oil bottles, for recycling. It takes about as long as it takes to wipe the boat down, and I get about 3 and 1/2 quarts out. Carefully done, my hands are still clean, and no oil is spilled.
When I get home, I thread the oil drain hose through the bottom of the boat, and let it sit in a container overnight. It takes longer to back the trailer in than it takes to get the hose into the container under the boat, and the hose into it. That is it for the first part of the oil change. Yes, the oil filter is still on the engine.

Overnight while you are sleeping, the dirty oil is slowly running off the internal surfaces of the engine. On the drive home any oil in on the top of the cylinder head and lifter valley has been moved to the front and back of the engine, by driving motion, and has run back down into the oil pan. The oil galleys in the engine have drained out through the bearings.

The original question was "Anyone know how to avoid a messy oil change on a GT-40"
By sitting overnight, the main oil galley that the filter connects to, drains into the oil pan.
This is the oil that would spill into your bilge if you removed the oil filter without letting the engine sit overnight. When I wait overnight to pull the filter off, I literally get a few drops of oil into the bilge. No plastic bags, no cut up milk jugs, no several oil soaked rags, no mess.
Waiting overnight, is simply my answer to the original question.
This is the method I have settled on with the 40 or so oil changes I have done on just my boat.

I also work on a 1998 Ski Nautique that has 1400? hours on it my church owns. the boat is moored, with no lift. When I do oil changes on it, because it is moored, I cannot do oil changes on it "My way" I have to suck the oil out, change the filter, get many rags soaked with oil, put the new filter on, and new oil in, and clean the bilge in one trip. The oil in this boat also turns to brown a lot faster in this boat than in my boat. I have to actually change the oil more often.

On my last oil change, on my boat, I actually let it go to 65 hours. At 50 hours, the oil was still a golden color, with a trace of brown. The two trusted mechanics that are on my ski team both said the oil was too clean to throw away so soon.

So, by waiting overnight, I have a cleaner engine internally, I can slightly extend my oil changes, I have no dirty rags, plastic bags, or cut up milk cartons to dispose of, and do not have to clean the bilge at each oil change.

I do oil changes both the quick way, pull the filter quickly, and the waiting overnight method. I think I actually spend less time on the oil change by waiting overnight, and doing it in two parts, than I do on the quick way, because I do not have to clean the bilge.

I certainly was not not criticizing your method, and if you read what I wrote, it was in part a compliment of your overall boat care. I simply do not have the time to spend part of two days on an oil change. I think that this is a very uncommon practice, which is all I meant by extreme. Perhaps there is a better choice of words I could have used. I am sure you have the cleanest oil possible when you are done. Nice explanation of your process.

Daniel - Your church has a SN? That is way cool.

Possibly Off Topic:

I'm with DanialC as most know already. My procedure is a bit different for my 5.7. I've posted it before in more detail so will be brief here. The oil I use comes in 4Q and 1Q containers. The oil for my trucks comes in 5Q bottles with quart markings. After the end of a good beating with the engine hot, I take her back to the barn and open the drain hose to an empty 5Q bottle. The next day, there will be between 4 and 4.5 quarts in there. Whatever I get out is what I put in to start. I haven't mastered what to do about the filter to get the most out of the lines. I usually take the filter off the next day. Once the gasket seal is broken, the oil in the remote mount hoses starts draining back to the pan for more (now cold) oil to wait on. 5.7 remote filter spillage is easy to catch so I'm thinking next time I might break the seal while the engine is hot to put some air in the line. Let it start draining then tighten the filter back. Once some air is in there...the oil trapped in the hoses should then all drain to the pan.

Note: the first oil change I did was in the driveway and did not drain overnight. I was limited to how much oil I could put in and the new oil was brown after a few trips. I won't do that again.
