It works well but it's w lot of extra stuff for something you only do a couple times a year.
Thanks for saving me the trouble of a failing experiment. Yet another example of how I really don't know how these loud things in the bottom of the boat really work. I think it is all just magic.

Lol no problem. But don't stop thinking outside the box. Some of the best stuff comes from the oddest places. My brother found some killer heavy plastic buckets at a kid's store. They lasted a good 5 years in my service truck.

This is the adapter I was talking about earlier.

I watched my mechanic remove the oil filter by punching a screwdriver through it to use as a lever to undo it.
If the screwdriver was punched through and withdrawn,could the oil in the filter be drained into a container via the hole punched in the filter?

Most definitely. That's how i do it when there hot. On something that small you could make a hollow punch and connect it to a oil sample gun and suck it out also. I use goldpeak ice tea bottles when I suck out injector holes. They screw right in the gun and are plenty thick so they don't collapse as you put vacuum on it.

I tried the punching a hole routine.

Thinking the oil would drain w a hole at the top for the air to enter I had high hopes. But I soon had oil all over the place. The oil came out the big hole as soon as I unscrewed the filter. There must be a one way valve in the system to prevent oil from draining at shutdown.

Next time I change oil I’m going to see if I can rotate the filter 1/2 a revolution without opening the seal at the engine attach point. If so I can punch a hole in the top of the filter as I did before. Then I can rotate the filter 90 degrees so the hole is at the bottom and punch a hole in the top so the oil flows out the bottom hole. But I’ll need to hold something under the filter to collect the oil. And wait for it to drain.

Not perfect and more time consuming but far less mess.

I have used the hole punch method before. It works to a point. However, when you take it off, you now have a filter dripping oil from both ends... Still, it can help.

Dave on my repower I had hoses to a remotely mounted filter. Worked really great but I had leaking at the hose fittings and eventually removed them.

Rip a piece off a pig matt and force it into the hole. It will keep it from leaking out.

You just have to run your punch deeper and penetrate the center core. I did some services on Isuzu's that were the same way but they had the filter mounted upside down. Damn thing would make a mess no what you did.

A check valve in the system is inside some oil filters.

Look in a filter crossover catalog to see if yours is designed for the valve.

On my Cummins big vertical filters I drained the filter into a gallon bleach bottle with the top cut open to fit over the filter. I let it drain while I changed the sump oil and by then it was empty. I used the handle on the bleach bottle with a string to hold it in place.
If you want no drips at all wipe the filter hole then stick on a piece of duct tape. It will hold well enough for the short time needed to remove the filter.

I use a hand-pumped vacuum sucker through the dip stick tube, and now I'm wondering if I could just punch a hole in the horizontal filter, which never seems to drain down on its own, and pull the oil out with the skinniest of my flex tube selection before spinning it off. I hate wasting a bunch of oil diapers on catching the spillage from the filter.

Thanks for that FF,
I was hope’in that was the case. I’ve been using NAPA filters lately and used Isuzu before. I suspect the Isuzu dosn’t have the check valve. Seems to me I’ve changed the oil in the past w the Isuzu filters and the oil drained w/o the hole punched at the top. I had a Toyota car w horizontal filter that drained at shutdown. No holes reqrd.

BIG CAT,
“Center core”? If one poked a hole in the center of the end it would seem to me half the oil would run out the punched hole.

If you want to install a remote filter and an adapter isn't available for your engine, most engine blocks can use the center threaded exit port and have enough material to thread the incoming port in the original filter spot. Then a couple hoses and an remote filter housing to fit a common filter can be added. Oil flow in a spin on filter is In thru the outside and Out via the center. If going to another filter, the longer the filter is, the slower the oil flows, and smaller dirt particles can be trapped.

Look down the middle of the filter. The metal tube that the elements bonded to is the core. You just need to drive it deep enough to nmake a hole in it so the oil will drain out of the center. Some filters hold oil back like yours. Sometimes it's because the design while others it could be a combination of things like oil temp, filter area, orientation, ect. 99% of the time when I do services we run them to get the temp up in the oil before we pull a sample and do the service. I go for about 140* or when it's not comfortable to touch the filter. It definitely helps get the oil drain not to mention the bearings have a fresh coat of oil so they aren't dry when you first crank it up.

Why not drain it down and install a drain hose and valve? You could always put a dry break fitting for connecting to a pump to pull it out.

Little Yanmar sailboat auxiliaries. No drain plug. At least, none that I ever found.

Haven't messed with many yanmars before but iirc the ones I did had a plug in the dead center on the bottom of the sump.
