We’ll show you how to replace the prop seals in your Mercury outboard in this video from Boats.net. The output seals for a Mercury Tracker 25 outboard come as part of a kit. For many people, replacing all of the seals at once is a good idea. We’ll start with the lower unit already removed from the motor, and if you need to see how to remove the lower unit on your Mercury Tracker, it’s here: • Mercury Tracker 25 Low...
We’ll open up the prop shaft carrier using a Mercury carrier tool, and then we’ll replace the seals and reassemble the lower unit.
See this diagram for a better look at the lower unit and prop shaft seals: www.boats.net/catalog/mercury...

Guys Ive said it before and Ill say it again, these are the most well produced, easy to follow, and all around best boat maintenance videos on youtube BY FAR. Please please keep up the great work!
Thanks mate. I’m in the process of changing my warped prop shaft and needed some guidance in changing these seals. You are a legend. Hi from south Western Australia 👍
....quite likely the most helpful video ever!....thank you
Thanks for the video! Do you have one that illustrates putting a complete seal kit in an older Mercury 25 hp 2 stroke motor?
Great video, John. Thanks for the guide. One question…are the seals installed properly? The service diagram mates the 2 seals with the aluminum against each other. Just checking
Great job gotta a question I have a 1984 25xd is that the same seal kit and where do they sell that special tool at thanks for the post
Man! You make this look easy. Now to rebuild my '62 Merc 1000 lower end... It'll go just as smooth...right?? lol
Where were you measuring from for the seal depth?
Would the need for a carrier tool be applicable for a 1986 Mercury 6hp?
Do u have a video on changing a bent prop shaft?
I didn’t have the special tool too unscrew it out I just used a big screw driver between the tab and prop shaft and came undone.
HI, I have a 1987 Mercury 25 hp 2 stroke outboard and wonder if you know if the process on this motor is similar to replace the prop shaft seals for our motor?
So you use red locktite on outside of both the seals before seating them?
That kit comes with 500 o rings though, great video! I have same engine, same problem
William Winters as do I. I’ve replaced these lower unit seals before and still have some leak and will just end up replacing all the lower unit seals this month and John started uploading at the perfect time! Haha
What is the part number of that special tool
My question is do I have to drop lower unit or can I leave it connected to remove the shaft housing?
I have a 25 horsepower Mariner with a very slow gear oil leak tiny drops. Would this be the same procedure?
On the inside of the lower unit housing for the carrier there is ALLOT of black carbon like crud and some white-ish colored crud. Perhaps Loctite type but resembles dried out plumbers putty. That appears to be keeping me from getting to the carrier o-ring and trying to remove the carrier. Suggestions to get that retainer plate loose given the crud would be appreciated as I don't want to scratch up the inside of the housing!
What loctite are you using?
I have a 2002 Mercury 25hp EH serial number OT413277. Will this seal kit fit this motor?
I can’t find the kit online research the exact part number on their website does anybody have a link?
Como se cambian los sellos que van abajo de la bomba del agua
Hi what about the shift seal on the leg .
I did the rest .
Im stumped on the shift seal on the leg
Hi, I have watched your video and it has help. But I have been trying to find the right tool , does anyone know who has this one. I order one and it ended up being a 4 prong. I need the 3 prong.
Similar specs for a 9.9?
You actually dont need that special tool, Mercury included it. Once the prop is off, remove the thrust washer. Inside the thrust washer there is a little key you can pry the metal cap off of. Then, you flip that key upside down and put it back on the shaft making sure it engages the three little tabs on the bearing carrier just beside the shaft. You can then slide the prop back on and turn it by the prop with a big ol 1 1/16" socket and a breaker bar.
My 1980s 25 mercs had these (had an 82&84, same setup as this one)
4:21. You block the view. Can’t see the measurement tools
