Changing oil

[Rosscoe]

I am wondering what you guys are using to change oil...what kind of pumps, good and bad experiences. I'd like to know before I buy one what to watch out for.
I am assuming it is done out of the dip stick tube.

I use an electric pump to draw the oil up the dipstick tube but there are manual vacuum pumps available for much less. Mine at the link below:

3 plastic Target/Walmart bags...make sure there's no holes.   I open the drain plug, let it drain into the bags, and then dump the oil into my catch pan I use for the cars.  Then I put it in my recycle jug for the next trip to Auto Zone.

I realize you have to have access to the pan & bilge to do it...but that's always been my method.

I have never had luck sucking it through the dipstick tube with a manual pump but I am probably not doing something right. AFter you get it drained put one of these in. Then the next time you need to drain the oil you just pull this hose through the water drain hole in the transom and let it drain that way. Just make sure the threads on the kit match your engine.

Yeah, that would work too!

I was planning to eventually mount one of these:

I bought a hand pump that screws onto the dipstick about 16 years ago and it works great. I always warm up the oil which helps. The only issue is it can be a little messy if your not careful, but it's fast and easy. The hose kits are great way to go if you have access to install.

I wonder when they started using those threaded dip stick tubes. My 74 does not have it.

I use this Top sider vacuum pump. Bought it about 15 years ago. Clean, easy to use and it pulls straight 30 weight oil in November.

I use a pump that you can mount on a cordless drill that has  both end with hose fittings.  Then i bought a washing machine hose with female ends cutin half. Warm up engine and pump it into a 5 gal pail take just a few minutes. All parts were purchased at fleet farm for under $20.00 bucks.

Your new user name still throws me for loop...I want GT Jeff back!

I have this installed on my CV-21 and it works great.  It was installed by a local High Performance Marine shop here where I used to take the boat for oil changes because of the mess and difficulty involved in changing the oil. The last time they changed the oil they did it while I waited and I was amazed that it took only about 20 min for them to do the oil change and asking "HOW DID YOU DO THAT" and explaining that it usually took me about 20 min just to clean up the mess I made let along get oil completely changed. It is a simple brass tee fitting installed under the oil pressure sender with a 4 foot piece of hose on it with a petcock on the end. Changing the oil is done by opening the petcock and putting the hose in a bottle or bucket and starting the engine.  It pumps the oil out in a matter of seconds.  Shut it down when it quits pumping.  I have gotten a lot of flack over pumping the engine dry of oil but I have never had a problem and the shop said they do that with most all the boats that come in.  They charged me about $50 for the installed fittings including labor to install it.  I imagine you could build it for a lot less.

Many good options.
That electric pump Rich uses is very nice but more then I want to spend, at least right now. The one Dane uses looks good too. I suppose a guy could put plastic down just in case.
I really like the idea of draining it outside the boat, especially since I'm putting in new carpet and it looks like there was an Exxon Valdez accident back there before. As a matter of fact I was scrubbing the floor with Dawn and engine degreaser tonight.
That valve in the link you posted Doran looks great but I dont think I have the clearance for it and I dont have any oil lines to tap into like Chris.
I think I'll get the oil out maybe using the "bag" method this time, throw a die on the plug to find out what the threads are and order one of those hose jobs. I never even thought of that. That is how they set up my mower because you can not even see the end in the block. I wonder if that hose can be extended or if its like my mower, the threaded part that excepts the bolt/plug is crimped on. The drain hole in my transom is on the opposite side of the motor from the drain in the pan. It is likely not long enough. Could probably extend it with some fittings.

Jeff I am unsure of your set up. Washing machine hose is at least 1/2"

Just went out and look at it, 1/2 od with 1/4 id it slips on the dip stick just right.

If you want to use it you are more than welcome as I change oil once a year.

Put 41hrs on the boat last year and was out alot. So they do not add up to fast.
