I'm just going to have to monitor this new exposure. I've always been very good at checking the motor prior to departure.
Yup, that seems like the logical thing to do.

You're concern (which I share) is justified. If that hose breaks while underway, the likelihood of destroying the engine is high. The hose on mine is very thick walled which also prevents it from collapsing under vacuum.
We have a similar setup. I discovered that the hose was partly worn-through from rubbing against the engine. Repalced it with a new hose that's a bit longer and so doesn't rub against the engine anymore.

Re: Changing Oil - an easier way?

My Atomic 4 uses the following Moyer Marine accessory. The extraction hose is capped, held against the engine "space" bulkhead with a hose clamp and is out of the way. I use a small hand suction pump that I connect to the extraction hose. I never counted the number of strokes! Really! The hand pump and delivery hose easily fits into a gallon zip loc bag then into a flat tupperwear container. No big deal. I do like having the extraction part of this set up permanently mounted to the engine as per Moyer's kit.

I switched to fully synthetic oil. Going by appearance and viscosity It stays cleaner longer and changes easily. It may give me a few rpms, too. We don't use the engine very much so changes aren't frequent. It is more expensive to use Mobile-1 or an equivalent but I am protecting my A-4 and reducing the frequency of this little chore.

This kit installs permanently into the 3/4 pipe-thread opening in the oil pan, just forward of the fuel pump. Handpump is not included.

Re: Changing Oil - an easier way?

As I said earlier, I just bought the Moeller extraction pump at the end of the season. No maiden voyage yet.

I just started wondering how one keeps oil from dripping out of the extension tubes while being stored? This thing going to become a mess maker?

Re: Changing Oil - an easier way?

Yanmar do not provide an oil drain plug for their GM series engines. I looked for a place to tap in a thread and fit a quick drain but can't see anywhere with enough metal.
Sucking it out through the dipstick hole is the only choice. I added about 10 inches of thin copper tube to the flex hose of the vacuum pump and it seems to get most of the oil out. At least what I put in approximately equals what comes out! I change the oil and filter every six months regardless of hours run ( boat used most of the year) and am happy that it is staying clean enough.

I suppose that only means you didn't burn any oil. To know you got it all, you should be pulling out an amount near equal to its published capacity.

Excellent plan. Making maintenace as easy as possible is a secret to proper maintenance.

Re: Changing Oil - an easier way?

Jabsco makes a 12 volt Vane pump which is reversable and does a good job of pumping the oil out and right back in. If you are lucky enough to have a drain plug on your oilpan a simple wire reinforced hose ( size ? ) installed correctly with chaffe in mind running up to the pump mounted next to your engine. Make sure you have enough hose on the discharge/intake side to reach your container. West Marine will probably have to order the pump as they do not normally stock it in most stores. I have used one for 10 years
and can change the oil and filters on my cats (4gals.) in about 15 minutes. It's very clean and efficient.

Re: Changing Oil - an easier way?

I use this on all of my cars and the boat. It makes oil changes a breeze and I have never had one fail. You can buy them from amazon, but I have never seen these in a store.

FUMOTO ENGINEERING

On the boat I use one that has a nipple to attach a hose to pump the oil from the bottom of that pan.

I've been using a 12v pump made by Quik-Drain for years, it's been great... Unfortunately, the company is no longer in business, but you might still find some laying around at some vendors... Or, Harbor Freight sells a small 12v fluid pump for around $30, one of those would do the trick, as well...

My Perkins has a dedicated tube out of the sump for changing oil, don't know why more manufacturers don't do something similar, so my system is permanently installed, all it takes is flipping a switch... Agree with the others who are nervous about replacing the drain plug with a hose fitting, if you're gonna go that route, be very careful and go with a top quality hose like Aeroquip, and make certain there's no possibility of chafe, etc...
We have a similar arrangement on our generator. Our drain "hose" however is high pressure hydraulic hose that is armored with a woven metal mesh exterior cover that was/is standard equipment on Panda Generators and ensures the hose will not suffer chafe failure. One could easily adapt the application to any other motor.

I don't follow you?

Gota store the oil somewhere? I guess I just don't see that as a big drawback as you say.
