 Topic: Oil Change - Slow to Drain?Posted: July-20-2006 at 10:55am |
|
I've recently changed the oil in my 80 Nautique. I noticed that it was very very slow to drain. The oil was in good shape, not black or anything. Is this typical? Any suggestions...Do it after a day running when the oil is warm?
Thanks Scott |

do it when it is warm or get a suction machine.

Try leaving the dipstick out.

tried that :)...still pretty slow. Must have taken 20 mintues to drain.
Thought their may be a block in the line so we hooked up an air compressor to the drain tube to clear...but no luck. We thought about a suction machine...maybe next time. |

I have seen the oil drain plug hose assembly apart and the actual hole in the pan plug is pretty small. Be patient. bj

i hate changing oil in these boats.
i dont have a drain tube which means i either let the bilge take the oil or use a suction device. i usually use the suction device but the problem with that is i can never capture all the oil. generally i can only draw about 3 of the 4 1/2 quarts it runs. so when changing oil i buy six quarts and after the first change i run the boat a bit and do the whole procedure again. i was going to buy a drain line from skidm a couple of years ago but for whatever reason skidm was uncertain that it would be adaptable to my 77 302. if anyone reading this post has installed one a 302 please let me know. |

Yep...run it and get the stuff warm! Remove the valve cover cap....if you have a drain hose , they are slower...let it drain for a while ....have a beer , a snack and a nap and come back to it!

77stang, nothing special. Just take the drain plug with you and match a fitting to the thread. Mine has an elbow style in the oil pan, and multiple ribs, once you slide the hose on, you can't pull it off.
(that's a six quart oil pan) |

I can't fit one one my 302...not enough clearance...pain in the rear!
What I done in the past is take a heavy duty trash bag and configure it where the oil drains into it and carefully remove it without snagging it...it's still a pain. I am going to try a new approach this weekend...take some heavy alluminum foil and form a drainage passage to the drain hole in the bilge and let in drain to a 5 gal bucket. |

thanks 72, creative minds are such a pleasure!
what type of wrench do you use to get at the plug, this has always been a problem also. |

I believe it is a 7/8's...I bought a set that is a shorter ratchet type and is angled...works well.

Buy a SuckUp from skidim. Will suck it dry thru the dipstick tube in about 10 minutes. Works great. No mess and no wait.

well the foil did work with mininal mess...took about five minutes to form a place!
SuckUp...I like the idea of draining down not up... that way the worst stuff does not stay at the bottom...my 2 cents worth! |

I put the drain hose in a jug or bucket and sit it beside the engine , put air pressure in the PVC hole , blow gun with a rag around it , cover oil fill hole with other hand or foot , takes 1-2 minutes to fill jug , take it easy with the air pressure not sure if you blow a seal or not

i just pull the plug on the end of the hose and wait til the following day. cause it is slow. but that elbow where the hose starts is very restricted. like 2 1/8" holes.

it's hard to let drain when your boat hangs in a boathouse , air pressure works great , did mine this weekend , with the oil hot it took under 30 sec to empty with 20 psi , unscrew filter , screw on new filter , pour oil in , done in under 5 min

and then I take a coffee filter , put it in a funnel and pour the waste oil in my diesel picktrucks fuel tank , it's like getting free fuel , don't put much more than 5 gallons of waste oil per tank ,it will start to smoke a little but makes the truck run great
