- In this video, I give a step by step guide for an oil change in the lower unit of your boat. This step by step guide will provide you with the tool and tips you need to change your own oil in the lower unit in a Mercury four stroke application. I have used Mercury Marine Outboard Motors for year, and they have been strong and dependable because I maintain them well. If you are tired of paying someone to maintain you outboard watch this video on changing your gear lube for a start. Thank you for watching and please SUBSCRIBE.

A little about me:
I am James McBurnett. I live in the great state of Texas. Probably not where you would think, but I am located in the panhandle region. I moved here from Alabama and work as a Chemical Engineer in the area. After being here for a few years, I decided to get back to my roots as a fisherman. It is quite challenging in my area to find a body of water to fish. The closest lake to me is about 40 miles away.
After a couple more years, I realized how much I love fishing and wanted to share it with the world. Clearwater fishing was born. I wanted to teach people all about fishing. This includes rods, reels, fishing line, bait, lures, largemouth bass, crappie, walleye, catfish, bluegill, boats, boat trailers, outboards, and anything else related to fishing.
I also wanted to share my fishing experiences as well. To be entertaining, knowledgeable, comical, and FUN. This channel was created out of the love of the sport of fishing, and I plan to keep making content that represents that. Thank you for watching this video and reading a bit about me. Give me a shout out in the comments below and let me know you read this. Now get out there and go catch you some fish.
Equipment I use:
Truck 2018 Ram 2500 Laramie 6.7L Cummins
Boat 2011 Bass Tracker Pro Team 175 TXW with 60 hp Mercury 4 stroke EFI
Front Fish Finder Garmin Echomap Plus 93SV with Livescope
Trolling Motor Motorguide Xi3 70lb with Pinpoint GPS
Console Fish Finder Lowrance Elite 9ti
Camera 1 Apple Iphone 8
Camera 2 GoPro Hero 5 Black
This video contains links which I may receive compensation.
Let me know how I did in this video by commenting. Did I do a good job of explaining and giving tips?
Clearwater Fishing thanks for the info now I feel better knowing how much gear oil the mercury takes👍
ed bulmer No problem sir. Glad to help!
great vid, think its about time to swap my gear lube as well.
This is the 2nd video ive watched from you to do my own work on the Bass Boat. Just want to say thank you & i appreciaye it very much!
Getting ready to change oil and lower end gear lube for the first time. Your videos helped explain how to accomplish these tasks very easily. Thanks for the info!
No problem. Glad I could help
Excellent video…quick, specific, and to the point. Thanks very much!
Glad it was helpful!
Nice job. Mercury recommends this every 20 hours of use. Each screw is backed by a yellow crush water that should be replaced with each lube job. The water pump kit has these yellow crush washers. There is also a seal to the lower unit in the water pump kit that should be replaced whenever installing new water pump. I have a 2008 60 HP 4-stroke mercury..only problem I've had was needed to replace the starter after ten years.
1 starter after 10 years isn't bad!
I guess your the lucky one…I bought a 60 merc bigfoot 4str 2018. I have had to replace the fuel pump THREE (3) times. Dealer says they use cheap fuel pumps
Thanks helped me just now here in Michigan
Glad I was able to help! Let me know how else I can be of assistance.
Great job -thanx-new to boating and your video was a great help
Your welcome! Glad I was able to help!
Thank you, I'll b done this week, let u know, thanks again,.
Awesome man! Hope it goes well.
Nice job!!! I have the same motor (2011) and have done all the maintenance but I want to change the water pump. Do you have a video on how to change the water pump on that motor. Thanks!!!!
Felipe Gutierrez Thank you! I do not. Mine won’t need changed until Jan 2022. They usually only need changed once every 3 years.
In another video, James is changing his prop and I need a new Trust washer for my Mercury prop like his. I think you have the same motor as him.
Sorry but = Is it possible and I would surely appreciate it if you give me the serial number of your 60hp Mercury motor? So, I could order a lot better thrust washer that I need to change on my 50 hp mercury 2006.
Maybe you would know the thrust washer's number on your motor? ;)
Thank you, so much
Sincerely
Gerald
Excellent, good job thank you
Thank you! I am working on a better one.
Good job, thanks for sharing Mr sir
You bet!
Good video and information
Great video 👍!
Thank you! 👍
Thanks. That was helpful.
Thank you very much for the video
You are welcome
Where did you get the yellow piece that screwed into to pump the oil in
It came with the pump kit, I bought.
So you have to do the upper and lower unit changing oil?
I typically do. My manual says to do it yearly or every 100 hours for both.
I read that Mercury recommends quicksilver premium 80w-90 for 75hp and below engines and quicksilver high performance 90w for engines above 75 hp. Ad never to mix the two. Have you ever heard this? I can’t imagine that they are much different than each other.
I never heard of this. I just put what they say to in the manual. I’m sure if you are in a pinch it will work just as good.
@@clearwaterfishing
Thanks. I have a 40 hp. I think I’m going to just use the higher performance and stick with that.
I have a 40 hp 2 stroke and am wondering the same. I think I’m gonna go with the Sae 90 too
You are correct. The 2 different gear oils are different colors as well. If you switch from one to the other drain completely first.
Please give me your advice? I change my gear oil see many air bubble inside the hose, turned out I forgot to add extension to the Pump. There is a lot of bubble inside the Gear container. So What I can I do now? wait over night so the bubble to release up and and out or redo all over again? Thanks
You probably don’t have to wait that long. Maybe a 3-4hours. If you need it done now you can drain it and start over.
@@clearwaterfishing Thank you much for your advice.
@@tydengr no problem. I wouldn’t sweat it. Just make sure you get most of the air out.
I have a 2002 mercury 60 4 stroke I did the lower unit and it only took around 300 ml oil came out of both vents how much did yours take.I’m just use to my evinrude 50 it would almost take a liter
I am so sorry it took me so long to reply! I must have missed your comment. It does not take much oil to fill my lower unit. I bought a quart 2 years ago, and after 2 oil changes it is a little over half gone. That is about 300 mL per change. Hope this helps!
Can I put 90hp propel to 60hp engine?
Do the gear lube screw and oil screw use the same seal?
No. They are different in my case.
@@clearwaterfishing thank you. I have a 99 50hp 4 stroke merc. Do I need to change my lower unit oil seal also? Or just my engine oil seal?
@@Tonymoss44 it is best practice to change both, but if it is in good shape I have run a couple of years on 1 seal. The risk is leaking and sucking in water.
How many pumps did it take to fill?
👍
Thanks!
I have a mercury 60 HP Command Thrust that carries 710 ml of oil. When I drained the old oil out a smaller amount, maybe half. It is normal?
Was the oil milky in color? If so, your oil may have leaked out. I wouldn't expect it all to come out. That stuff is pretty thick and like to stick to the metal in your lower unit. If it isn't milky, I would call it normal. If you want to get more of it out, run the motor in gear for about 10 minutes to warm up the oil. Obviously you want to do that before you drain some oil out.
@@clearwaterfishing the oil was normal in color. Maybe I didn't let it drain enough. Thanks!
If the motors have the bigfoot lower unit, they will hold 710 ml. If not, they will hold 330 ml. Mercury has a specification for lubrication levels online.
The volume could be set higher. I needed to put my volume to the max to hear you. Then, when a commercial came on, it blew my ear off.
Sorry! This was one of my first videos. My audio is better now!
Do these motors have an air filter?
No air filter. I thought it was odd myself.
I vant HEAR YOU
Good explanation...sound is poor.
good video but your volume is way too low and can't understand everything you say
Thank you! I have made many improvements since then. My microphone is much better now.
Record your videos with HIGHER VOLUME! I could barely hear wut u r saying at full volume!
I can hardly hear you ...and u didnt torque
I have fixed the audio since then. I need to redo these videos. What do you torque it to?
do you have a tilt and trim repair?
I do not. I haven't had issues with that yet. knock on wood!
