Installing a dedicated oil change pump

[mondofromredondo]

In the interest of making another dreaded chore less of a drudgery I am considering installing a dedicated oil change pump. Most likely plumbed to the oil drain plug at the bottom of my 3GM35F.

Has anyone tried that might have some input ?

I believe I'll install the pump on the engine room stbd wall next to the fuel filter.

I like the idea of flipping a switch and having the old oil simply poor into a drain bucket. Not sure if this is an option but it would be nice if I could simply (after draining) reverse the process with clean oil. How cool would that be ???

Thanks for reading!

The previous owner of my 37 had installed a pump for just this reason - installed it just below the Racor filter on the starboard wall as you describe. It works like a gem - although in the last year or so, I've had to bang and wiggle the contacts to get the pump going - but it's always started for me. Makes changing oil a breeze.

I recently sold the 37, and now have an Outbound 44. Just to make you REALLY jealous, this boat has a generator too... Both the engine and generator are hooked up to an X-Change-R (X-Change-R® Oil Change Systems Reversible Impeller Gear Oil Pumps Marine Service Maintenance) system which will allow me to drain - and refill both units!

It seems to me to be an over complication for what is after all only a once a year task.

Keeping an uninstalled pump nicely wrapped up for most of the year and only bringing it out when needed seems a good way to prevent things like contacts getting clagged up.

Fortunately, I have not installed one. Equally fortunately, I'm really pleased that the previous owners of both my PS37 and OB44 did! I used to HATE the annual oil change procedure on ourS2 with manual pump out of the dipstick - and then trying not to spill remnant oil out of the silly pump - for years after! I still have that pump - and it still leaks black oil every time I move it from one spot in the basement to another! Any one want a manual oil removing pump - going cheap!

I really like the automation associated with changing oil! (Can yer tell!???)

What oil drain plug? My 3GM30F doesn't have one, and neither did my previous 2GM20F's. If you've got one, someone added it, you lucky devil.

ah .. I take your point. I have a mate who comes over once a year, gives the old donk a check up and while he's at it changes the oil. His pump has never leaked any oil at all.

On NiftyNickers we have a Beta engine with a oil change pump built-in.
All filters and pump upfront --what a concept.
Previous engine Universal 5432 installed electric oil change pump--Beautiful thing!

Good luck,

Something like this oil extractor pump and bucket: Economy Oil Changer Pump - ITT Jabsco 17850-1012 - iboats.com
makes extracting your old oil quite easy and is nearly dripless and clean. Once extracted I bring the unit home and use my car battery (with engine idling) to pour the old oil back into containers for recycling. I hardly ever spill dirty old oil but have spilled clean oil when refilling.
I'm sure it is handy to have an oil extraction/refilling pump on your engine but it does add an extra system that can be damaged or fail.
I use a 12V pump bucket like the one I linked to above twice a year for oil changes.
Your boat, your choice.

Yanmars have the oil filter on the side, anybody figure out how to change the filter without spilling oil?

Unbolt the engine mounts, decouple the prop, disconnect the muffler, attach a hoist, lift the engine till vertical and then remove the filter!

Sorry - Couldn't resist!

I always put an oil blanket right under the filter before spilling dirty oil all over the place... System sucks!
