| Post subject: | Oil evacuation systems for changing oil. |
Any recommendation on brands and types of oil evac systems to change oil in my boat. I do have the threaded fitting. What's better. 12 volt pump or pneumatic or hand pump. Also does anyone know how to make Pics on here bigger? Thanx =  2000 FW Horizon 210 5.0 Volvo |

With any of them they work better if you use the garden hose thread connection at the top of the dipstick tube if your engine is so equipped. Much better than snaking the little plastic tube down the dipstick tube. I have a Topsider it works pretty well. I also use it for a lot of other stuff, makes changing the oil in 4 stroke yard equipment very easy and much less of a mess. |

Lou, do you have any links or more info on the garden hose things? Thank you. |

Take a look at the top of the dipstick tube. If it has a larger threaded fitting at the end, you can get a female garden hose fitting that will screw onto that. Now you have to find a rubber hose that fits onto the end of that fitting, that gets connected to the hose on the vacuum pump. |

Both of my engines have them as well as most other boats I work on. I just don't understand how they'd work. As a mechanic, I've removed many oil pans over the years. The full mark on the dipsticks extends beyond the bottom of the dipstick tube. I can't see how it can extract the oil. I could see it working if the dipstick tube extended to the bottom of the oil pan. I'd gladly invest in whatever it takes to make my job easier. Mercruisers with 25 W40 take forever to extract, even when fully warmed up.

I purchased one of those jabsco hand pumps off Amazon a few years ago that screws to the dipstick for around $35 on sale. Warm the engine up and about 15 pumps later it's empty. Would take longer to plug in an electric pump than do it by hand with one of those bad boys. http://www.amazon.com/Jabsco-34060-0130 ... m_sbs_sg_1 Keep in mind it's nothing like the one that goes DOWN the dip stick with a tube. Tried one of those once. Took 30 minutes to get the oil out! |

Most marine engine dipsticks either do exactly as you hypothesize, or, more often, the dipstick tube actually connects to where the drain plug on the bottom of the pan normally screws in. Gotta make sure the oil is hot, or it takes forever indeed, and yep... even warmed up it's slow! |

Thanks kd4pbs. I "think" I see what you mean. I have a customer with twin 454 Mercs running 25 W40 with STP added and it takes me forever to evacuate them. Even hot. With a 4 hour return trip to his boat, this is no fun. If I could save just 1 hour, it would be worth it to me. |

The dipstick tube on my old OMC, and on Volvos I have seen, does connect to the very bottom of the oil pan, so it can get nearly as much oil out as manually draining. It is sucking from the lowest spot. I can see if they used a normal (automotive) dipstick tube going into the normal spot in the block it would be very difficult to get the oil out. I think that the tube must extend into the pan, or else there is no way you could get most of the oil out. I use the Merc 25/40 and it sucks all the oil out in 10 min or less. Why is he using STP, absolutely no need for that. Here's a diagram of mine, the dipstick tube part #66 attaches to part # 48 http://www.crowleymarine.com/johnson-ev ... /55437.cfm |

Thanks Lou. I see how it works now. He uses STP because it's real old and tired. Without it, they'd sound like 32 woodpeckers trying to get out.

Well then I can see why. It's all good till he tries to start it one cold day and the 25/40+STP all coagulates like a lump of molasses around the oil pick up.... BTW I use that vacuum pump for all kinds of things, sucking the diff oil out of the Jeep differentials, changing the oil in all my 4 stroke yard equipment (makes much less of a mess), if you put a little to much trans fluid in your auto trans its handy to suck it out. |

I've used the manual suction pump for years and it still works perfect. I bought the tubing to go into the dipstick tube and I push it down til it hits the pan. Not sure how much farther it extends beyond the tube but I feel comfortable hearing it sucking oil from the empty pan. I run engine to warm oil and it doesn't take long but I use synthetic blend oil. I use a long tube so don't even have pump in the boat. I let it pump oil and by time I swap oil and fuel filter its done. Either way is fine as long as you change the oil. |

I picked up one of these a couple years ago because it was all I could find locally on short notice. http://www.northerntool.com/shop/tools/ ... MgodgQ8A4g I've used it three times now and it does the job surprisingly well. |

I bought the Pella 650 evac system. Let the boat run about 15 minutes. Hook it up and in 5 min. it was done. Fantastic product. |
