I changed my oil last weekend for the first time since taking delivery of the boat just over a year ago. The engine only has 45 hours on it, however I figured an annual oil change wasn't a bad thing. I used the Tempo pump from West Marine, but was very surprised to only get just over a quart of oil out of the engine. The pump was drawing very little oil after that volume and bubbled in the tubes when I added a few more strokes to the pump. I thought the manual said the oil capacity for the 3JHE was 5 liters. I also changed the filter. When I added new oil, I was careful not to overfill. After checking the dipstick after running the engine a couple of minutes, it read full. Did I get out the majority of the old oil or do I have a mixture of mainly old oil and just a little new? What else should I have done? Thanks, Steve S/V Options

VOLUME
Just used the same pump to change the oil in our 40.5 Yanmar 4JH through the dipstick and was surprised how well it worked! Got virtually all the oil out in less than 15 minutes. Was your engine warm when you tried? Don

Check the angle
If your pump hose has a natural curve (as most do), you must thread it into the dip stick hole so that the tip of the curved tube reaches the lowest point of the oil pan. If not, it could curve right back up out of the oil and you'll never get the full amount out. Also, ensure that the engine and oil are warm before attempting to change it. Even if you live in Texas. It's important to circulate the oil to suspend any impurities from the engine so that they will be sucked out. As far as your situation, if you got out all of the oil before you replaced it, you should have enough room to replace it all. As in my 3HM35F, I would assume you have about the same amount of oil, which is slightly more than 5 qts. Check your service manual.

Steve: A Quart Cannot Be Right
Are you sure? You don't say how much went back in. An FYI on the dip-stick changers: you can push the hose in too far and have it loop back up, thereby not evacuating all the old oil. When it starts pulling air, pump some more and move the pick up tube in and out to see that you get it all. You may have a re-do. At least your hourly rate is cheap enough, but you don't have the satisfaction of nagging the mechanic;^ Good luck, Rick D.

I got out a little more, but not 5 liters
I changed the oil twice on my 380 with the same engine. I called several shops (and Hunter) and they all told me there would be eight quarts (5 l.)in the 3JH2E. Anyway, I pumped almost four quarts out after making sure my pickup tube was all the way to the lowest point in the crank case. I changed the filter and put 4 quarts of new oil back in. Oil looked clean as could be after running for 1/2 hr. Where the heck is the rest of the oil hiding?

patience
Steve, I did the same thing when I first changed the oil. It has always bugged me what happened but I could not believe it and kept trying. The recent most oil change, I was thinking about the first experience. If you overpump it, it will gurgle. When it stops gurgling it is still pumping. It sounds like it is finished but it is not. Make sure your oil is warmed up. Pump it a few times and BE PATIENT. It will fill up to the 4th line on the outside of the canister. Any questions, please feel free, Mike D

Told you so, Rick!
Rick - here is one fluid chart I just found on the Internet indicating 8 qts. (see link) Torresson Marine as well as Mack Boring also told me in direct phone calls to their Yanmar experts that is was 8 qts. Hunter said to go with Mack Boring's recommendation. My manual says 8 quarts but I did not believe it so that's why I called in the spring. Anyway, I got two changes out of the 8 quarts I purchased. If they say 8 it should be 8, not 4. How could so many be wrong? I did have a 1985 H34 with the 3GMF30 and it was barely 4 quarts. Now we have the 380.

That's Weird John!
I have a 4JH2E now. It also calls for 8 quarts. I usually change my own and put in about 5 as I recall. I looked at an invoice for a change by the Yanmar guy and he charged me for 5. So where does 8 come from??? I see that the three-cylinder has two different capasities in two models, 2.5 and 8 quarts. Hard to figure the three and four model blocks would have the same oil capasity... which I do not believe I have anyway! Beats me. I will continue to fill to the top dipstick level in any event. Thanks for the info. Rick D.

mountain or molehill
You are ALL trying to make a simple job as hard as possible. Your car(and millions of others) has a drain plug on its crankcase to make draining the oil easy. Why guess how much oil you have left in the engine? Put in a drain plug and be sure you got it all. Whats so hard?

Filler Cap
Steve, I have found it necessary to undo the oil filler cap before trying to suck the old oil up the dipstick tube - otherwise no air can get in. The oil system is normally sealed to the atmosphere via a pressure relief cap or valve.

Thanks All
I appreciate the response from all. Yes, I checked the oil level before pumping it out and after the change; the level was the same. I ran the engine for 5 minutes before the change, however it was a cool day and I may not have warmed the oil enough. I think the biggest error I made was not getting the line past the L-shaped curve at the bottom of the dipstick tube. Next time, I'll use the smaller diameter line and work it around the curve into the pan. There is still a lot of confusion about the oil capacity of the 3JH3(C) engine. My owner's manual says 5L. I can't see that equating to 8Q. In the first place, a liter is larger than a quart (3.785 liters = 1 gallon). In that case,a liter = 1.0568 quarts. 5L x 1.0568 = 5.284 Q. That's a far cry from 8Q. So who's right? Fair winds, Steve S/V Options
