Engine Oil Extraction

I use the drain plug ! (1gm10 ) Its quick - and I get to clean the metal spring filter as well.

Its only a litre and a half - and I drain it with two ( holeless ) plastic bags doubled up - taped to a small paper collar about 6 inches diam - and about 30mm deep. virtually no clearance needed - and the collar can be tilted to suit the initial flow with out disturbing the collecting bag - and before you say it - no. I have never had the bags snag or leak.

Why do you have to clean out the Pela container?:confused:

Well, I store mine on board so I’d prefer not to have oil left in it to ooze out into the locker if not kept fully upright.

Not a problem, though, because I always change the diesel filters at the same time as the oil, and use the pela to empty the jug that catches half a litre or so from the old filters. This washes out the inside of the suction tube, and swills the oil off the inside of the ball. The diesel is runny enough to all come out, unlike the oil, and it goes into the same container to be disposed of into the tank ashore.

I'd like one for water with a long reach to get at the bits of water under the engine that the bilge pump won't suck.

Get one of those flexible grabbers and get it to grip an old sports sock. This will mop up those bits of water under the engine really well. Just be careful not to short the battery
 
Do not use an open dish or "halved" oil can under the sump then remove the drain plug and let the oil flow into the receptacle, unless the full receptacle can be removed without tilting.

Don't ask me how I know.....................:rolleyes:

I like the idea of two plastic bags and "funnel"; either using the drain plug method or the Pela-type pump.

I have a Kubota 13HP

PS Easier to handle than the Pela and just as effective is the "brass oil change pump" as sold be Force4 (£17.95) and others.
Cheap enough to have one for oil and one for other needs.


PPS Thanks for the alert to change the oil filter - which I have just remembered I didn't do last month. Doh!
 
Another vote for a cheap Aldi/Lidl pump. We used a Pela a couple of times and found it very slow. We used the electric pump last time and pumped the oil into plastic milk containers. No mess and much quicker.

we have the lidl one at work, had it a year and it gets used at least once a week, very good tool for the money. WE use it for priming diesel systems as well as sump evacuation
 
Some good suggestions there, thanks all.

The next thing I need to find out is how to supply water to the cooling system while the boat is out of the water. I'm thinking of sticking a hose into the inlet with the other end in a 5 gallon water jack and perhaps a way of catching the water coming out of the exhaust and returning it into the jack or perhaps just topping it up as it goes, not sure how long it would take to get through 5 gallons. Any comments/suggestions ? Thanks.
 
You could stick a hose up the intake, connected to the mains, which seems to be the usual technique. Not a brilliant way as water goes everywhere and you're in trouble if the hose falls out. I've always avoided running the engine on the hard, but if I had to do it I'd probably lead the hose onboard and directly connect it to the hose connected to the engine.
 
The only time I've done it, I put a big bucket under the boat as close to the intake as possible and shoved a short hose into the inlet and down into the bucket. I then had a separate hose filling the bucket from a tap. All seemed to work OK - you just need to ensure that the hose jammed into the water inlet is secure so it doesn't fall out.

Invest in a small 12v electric pump available from just about anywhere,most recently Aldi or Lidles, for around £12-£25 pounds.
Mine came with two sizes of inlet pipe,one small enough to go down any dipstick tube.

The electric pump is also useful for pumping out bilge water from difficult corners

Do you have a link to an electric pump which will pump water, engine oil and diesel?

I am still interested in that link Oldgit. I'm assuming that you're not talking about the Aldi/Lidl pumps as I have two of those but they can't be used for water.

.....sorry for delay in reply
Used the Aldi pump for pumping out bilge water but did run diesel through it afterwards to remove all moisture.
No problems and dead easy to get those last few dribbles normally left for a anal sponge wielder like me.
It was also used to pump out oil from my Smart Roadster, believe it or not , no sump plug !
Previously used vacuum oil pump from "Snap On" tools to do the job, the electric one did it far more efficiently and quickly.

Not a good idea, I think. Not only can it be messy, but if the hose supplies water faster than the engine needs it you end up with a flooded, hydrolocked engine. I've known this to happen. A simple bucket suffices as a buffer, but if you want to run the engine for some time a five-gallon drum sounds good. It sounds like a disaster waiting to happen, but in practice it works fine as long as you don't leave it all unattended, and make sure the hoses are secure.

Bit of a problem if the inlet is covered by a grid. I've used a tank on a barrel with a larger diameter hose to catch the output and then a hose connected direct to the inboard filter. Bit messy but you will be surprised how fast you will use up 5 gallons.

Obviously you'd make the join properly to avoid the mess. I guess there is a theoretical risk of flooding if the yard water supply doesn't have a tap to control the flow. Personally I suspect the water flow down a significant length of 1/2" hose wouldn't keep up, but it would do something to keep the exhaust from overheating. But you're right to point it out as the OPs boat will be different and it may be an issue there.

Of course the best way is to avoid the issue by changing the oil when the boat is in the water.

So do most people change the oil before the boat is lifted out for the winter ?

OK .... I did think about running some oil through mine, then using it for water and then another run through with diesel but have never tried. I might try it now. Thanks. :)
