| Post subject: | Oil Change with a Shop Vac |
I was trying to find an easier way of changing the oil in the 220. The manual pump is for the birds. It took forever and was a PITA!!! Was thinking of a forced air / air compresser to push oil out of the dipstick, figured that I couldn't seal up al the vent holes on the block. Saw an old 2 gallon shop vac that I haven't used in years and decided to try it. Piece of garden hose attached to the dipstick, packing tape wrapped around the cutoff end to fit in the vacuum hose end, more tape to make it seal, take off the oil cap (just in case it creates a vacuum in the block) hit the switch............... a little over 5qts out in about 4 minutes!!! I couldn't have asked for an easier oil change. I think I spent 1 hour hand pumping last year..... Maybe I should patent it...... Poured the old oil into the empty oil container for recycling....and I'm spent...... |

Try this, do warm the engine up for a few minuets. That will thin the oil a little & make it easier to pump out. http://www.imarineusa.com/jabscodiyoilc ... ucket.aspx |

thanks for the tip on the warming of the engine :s), I was wondering why it was so hard to pump out in Dec....., I have a perfectly good shop vac that wasn't being used, Voila, saved $100 The hypothesis was proven to me, maybe someone else could use the knowledge...... |

Simple math... Oil vapor/mist + Electric Shop vac (some are actually DC, rectified) = KABOOM. ... unless your shop vac is rated for explosive atmospheres, I would hand pump it. Only takes a few minutes with the engine/oil warm.... I'll bet it takes me less than 4 min to pump mine out this way. I've been out with your boat (previous owner) and would hate to read about such a thing in the news! |

Also, there are many hand pumps that are nearly worthless, and not that many that are actually good. In fact I don't really know anymore who makes a good one. I've got a Tempo that everyone used to rave about, but I think they've been out of production for awhile. |

I would not use a shop vac for the reason listed above, oil is flammable. I use a Topsider vaccum pump, it is well made and holds a lot of oil. I found the easiest way to do the oil change is to use a garden hose adaptor on the dipstick tube and that sucks the oil out much faster than the thin tube down the dipstick method. You do have to warm up the engine first. I also use the Topsider for lots of other jobs, sucking gear oil out of the diffs on my Jeeps, to make an auto trans oil change a no mess experience when there is no drain plug on the pan, and to change the oil in my lawn equipment machines without making a mess. |

I would not worry about oil fumes too much. Motor oil start flashing at 220 - 240 degree celsius. It would be the gas fumes that would need to be considered, not so much the oil. BUT, the fumes in the vac will coat the motor, brushes, fan any thing in the Vac. bringing it to a stop. Could it cause a fire, yes. Most likley, no. I would not do it, I would not want to find out if it could!! NOW thats this my take, I could be wrong and again, I would not use a vac anyways. I bought the pump in my past post above. It works good, not great, BUT you need to warm the engine first. |

I was going to second Cap'n Morgan's hand pump recommendation but the post disappeared. That is the same hand pump that my tech uses and I was amazed at how quick it was. The one-time that I changed my 298's oil, I had purchased the electric pump of choice that is in all the marine catalogs and the hand pump does just as well and is a lot cheaper. My tech uses the white one.

That would be the Mityvac MV7400. Best pump extractor for fluid removal, and the price can't be beat. http://www.amazon.com/Mityvac-7400-Lite ... B000JFJM14 You can even get it at auto parts stores like O'Reilley's. |

Jeff, I have used those a few times. They are slow in evacuating the fluids, but they do work just fine. It is a night and day difference between the Liquivac and the MityVac NC7400, as far as how fast it pulls the fluid out. |

Hey Cap'n, Does that Mityvac pump give you the option to use the hose connector at the top of the dipstick, or do you have to use a tube? |
