I have Jabsco
unit, reversible pump on top of a 5 gallon bucket, works good for both engine
and trans and it will pump really hot fluids of almost any kind.
I really wonder why marinized diesels don't have the drain plug
at the low point of the sump which is usually the back of the engine
. Ours has a drain tube for oil
changes on the drain plug
which is ingeniously mounted at the front of the pan, almost the highest elevation. I can get more oil
sucking from the dipstick tube, but for sure I can't get it all. I feel this is partly why diesel
oil goes black so fast there is always a cup or two leftover to contaminate the new oil.
My Kubota tractor has two drains in the sump, I let it drain overnight when I change oil and I can go 50 hours before the oil starts to go black. The oil in the Kubota engine in the boat goes black about 5 hours after it's changed, both engines are within 50 hours of each other and they both work great. I know, I know, it's just soot, but I still hate that. If I ever have to pull the pan for any reason it's going to a machine shop to have the drain plug moved to the low spot in the pan, then the drain tube on it will actually be useful.
