Messy Oil Changes

I hate to confess a not so correct way I have done things;
Get them hot, pump the sump. Next day; pump the sump again.
Then remove filters.

Yes, yes; it's not the way it's 'spose to be done. Breaks near every rule and quality rule there is in oil changes, BUT; in tight places, less mess, no burns or scars, it works.
If it's yours, you know it. If it's a customer, tell him. Then sell him a fix; remote filters and a oil change pump.

I do the oil changes on the 3412Es here on the boat I run, 40 gal and two big filters per engine... It took me a couple of times but I know manage without spilling a drop

First, I would NEVER use open pails to collect the oil, I ve seen guys carrying open pails down the dock, that s nuts. I reuse pails with the lid on, putting in the hose from the pump in the hole instead. This way they are sealed tight.

Garbage bags don't work well for me to catch the oil leaking from the filters... Slippery, can tear, etc... Instead I use a small bucket, large enough for oil coming from the top of the he filter to be caught, but small enough to fit between the filter and the block. A slightly flexible container helps, like a gallon size mixing cup. Whatever fits. It allows me to support the filter from the bottom when it slips off the thread at the end.

I also set up a big box, lined with a compactor bag and paper towel at the bottom to store the used filters. Also, I keep a pail nearby with a funnel to drain the filters before putting them in the box. Same trick with the bucket for the two secondary filters on each engines

The next one isn't needed with a smaller Detroit as you only need a pail or engine, but I use a hose long enough to reach outside the boat so that I don't have to lug 9 pails (8 for the mains, 1 for the gennies) on board. Zip tied to the hose, I have the wires to a remote switch so I can control the pump from out side as well. To catch any possible spill, I place each empty pail being filled in one of those small concrete mixing tbus from Home Depot... They re like 18" x 30". Our finger pier extends far enough to reach close to the ER, on sport fish you could easily set up in the cockpit but on some MY it s a lot of carrying up the deck and down to the ER

This has worked for me very well and I usually don't spill a drop in the process.

Interesting idea. What size pump are you using? I assume that the hoses lead through vent openings?

It's just your basic oil change pump. All I did was to add an on off switch tapped in the pump power supply. I still set the fill / off /drain switch on the pump but can turn the power on or off from outside

I run the hose and wire up that stairs thru the salon door or into the master a
And out a porthole. But on many boat you could also run it thru the ER vent. When I got on the boat 5 years ago, the hose was long enough but there was no switch so it was a two person job... Made no sense...

It s a back saver! carrying 8 or 9 pails up and down isn't fun
