I was having a problem oil leak and determined that the pan was overfilled because I left a few quarts in the pan each time. It is a 425HP with baffles. I was so please with the ease and simplicity that I installed another hose in my transmission so I can pump it out. It makes oil changing quick and clean. If I could only figure a way that the oil filter did not leak when loosened, it would be a pleasure changing oil.

take a phillips screw driver and poke a hole on top of the oil filter and wait 5 minutes,all the oil drains out of the filter and into the pan.spin the filter off.:cool:
I assume the Merc filtes have an anti drain back valve in them, so why do they drain back even with a hole in them? |

The next day when finishing the job at home, that filter was empty. Not a drop spilled. Cool! So poked a hole in the other filter, after a few minutes, it was still full. Appearantly it takes some time to drain.

The later model dipsticks drain from below the oil drain plug. I slide a piece 3/8" fuel hose OVER the dipstick tube and I get most of the oil out with no problem. It's much faster than that little plastic hose you shove all the way down the tube.

been doing it that way for years,works great. Last year I was getting my boat ready for summer,I drained the engine oil thrue the dip stick tube,pulled the outdrive to check alignment,noticed the coupler needed to be changed. removed the engine and replaced the coupler,while the engine was out I figured it would be a good time to remove the drain plug and get ALL the oil out. All I got has a couple of drops out. |
Went out tonight and used my handy dandy AutoZone hand vaccum pump. Shoved a stiff piece of tubing down the dipstick until it hit bottom. Between the 2 motors, I got just a tad shy of filling a 2 liter bottle full of oil. I could hear it sucking the oil off the bottom of the pan when all done.
Looks like the large vaccum type pump can with a small tube will work as an alternative to the drain hose. BTW, my drain plug is on the bottom of the pan. '99 502's So the newer motors have the drain plugs on the sides? |

No,sir. The dipstick tube threads into a brass fitting that replaces the drain plug in the bottom of the pan. |
