Oil changing on F75


Mueller

Recommended Posts

Has anyone ever used one of those gizmos that pumps out oil from a 4 stroke that pumps it out through the dipstick tube? When I change oil on my F75 its quite the mess...I'd like to minimize the spilled oil and thought that if the dipstick pump works I'd get one. Or, if that doesn't work do any of you have a technique that I could try.

Replies appreciated

I just changed the oil on my F75. Get another set of hands. I had my buddy hold a 5 gallon bucket and I took the plug out. Didn't get a drop of oil on the floor only some on my hands. When it got to the point where there was only a slow drip of oil I taped a small plastic cup below the drain and let it drip for 1/2 hour. Before removing the filter, I packed some paper towels below the filter. However, when I removed the filter, I quickly tiped it upward so it would hold the oil like a cup. Didn't get any mess. The only bad part is I now have to transport my used oil. frown.gif

I just changed the oil on my Merc 75hp 4st EFI last weekend and used the PELA OIL PUMP EXCHANGER 6000 model, which hold over 5 quarts. It worked great, no mess at all, it did take well over an hour to finally get all the oil out but did give me time then to full drain the lower unit and change that out too while the oil pump was working. They are a bit pricy. I'd give the Pela 6000 oil change pump 5-stars.

The problem with pumping the oil out with these devises is that it doesnt take all the oil off the bottom, it leaves the metal filings, and dirt on the bottom, and it doesnt take out all the oil. To use it properly, suck the oil out with it, then pull the drain plug afterwards and rinse engine with a few ounces of clean oil when drain plug is out. But then you still have the mess of the drain plug, so you might as well pull it out from the beggining!

    • As a recovering machinist, I can appreciate that.  If the spec is 0.001 - 0.0015, then clearly the correct measurement is 0.00125, duh…
    • I just figured that it is easy enough to just get a 3 bank so when the boat is not in use I can keep all 3 batteries charged. I have not bough a charger yet, maybe I will give it some more thought. Edit: After thinking this over, with the size, weight, and heat output of the charger (as well as the cost) I think it makes sense to just buy a 2 bank charger, I have a smaller charger i can use on the starting battery when the boat is sitting at home. Forgive me, for i am a retired engineer and I have to obsess over everything...
    • Congrats on the motor!  I think you’ll like it.   I can’t say much on the charger location but I’ve seen them under the lid in back compartments and under center rod lockers.  160 degrees is more than I expected to hear.   Curious why you’re opting for a 3 bank charger with a 24V trolling motor.  Unless you don’t feel you be running you big motor enough to keep that battery up as well?
    • I did buy an Minnkota Ulterra, thanks for the recommendations. I had a bunch of Cabela"s bucks saved up, which helped. Now i need to get an onboard battery charger. Where do you guys mount these things in your boat? The manufacturer I am looking at {Noco genius) says tht their 3-bank charger will run at 160 degrees, seems like a lot of heat in an enclosed compartment? Thanks for any input on this.
    • You're very lucky a troop of Sea Monkey's didn't carry you away.   
    • Wasn't terrible at a state park beach. Antelope island maybe.  I wouldn't recommend it as a beach destination tho.  Figured I was there, I'm getting in it.
    • The water looked and smelled disgusting with hundreds of thousands of birds sh*tting in there.  About as gross as the Salton Sea. When I duck hunted there I didn't even want to touch the water.
    • It's kinda gross with the algae in the summer but I got in it anyway.  Wanted to see the increased bouyancy at work.  You can kinda tuck yourself into a ball and you'll just float with your head above water.  When dry off you look diamond encrusted with the salt.
    • We went to the flats too. I dipped a tire on the rental car onto it just to say I’ve been there,but it was still pretty soft from winter melt. After seeing some moron in a BMW suv get dragged out of the muck I had no intention of repeating his stupidity. 
    • I've been out on the flats. It's like being on a different planet
