John will show you how to replace the prop seals on your Mercury outboard in this video from Boats.net. Removing the lower unit isn't necessary for this job, but we’re also changing the upper seals and replacing the water pump on this Merc 40, so we’ve already removed the lower unit. If you need to see how to do that you can check out this video: • Mercury Tracker 40 Low...
We’ll start by removing the gearcase fluid. Then, we’ll get the prop off so that we can access the bearing carrier assembly. With it removed, we’ll pull the old seals and replace them. Finally, we’ll get the bearing carrier and prop re-installed on the outboard.
See this diagram for a better look at the lower unit and prop shaft assembly: www.boats.net/catalog/mercury...

In the video we’re working with a 2003 Mercury 40HP 4-stroke EFI outboard motor, but you may have similar steps for your Mercury outboard. If you’re not sure whether these steps apply to your motor, leave a comment and we’ll get back to you.

Hello John. Thanks for sharing your video. Excellent, clear and professional explanations. Thanks and take care. Mike Canada
On my Mercury Force 40 from 1996, I couldn't get out the oil seals like this. They were a nightmare and I ultimately was able to finally get them out with a 14 piece / 2lb slide hammer kit from Harbor Freight - but only after heating up the housing a good bit with a blow torch. Massive thanks for this post, it was incredibly helpful and hopefully what I've shared here helps someone else whose prop seals are really stuck :)
Good luck doing this again in the future with that red Loctite. I would hate to have to put a torch to those aluminum parts just to disassemble. This is why they make blue, and purple for extra small stuff.
1:49 THE BEST PART :D sounds like closing door
Стойка под редуктор отличная !! У нас такая есть , стоит конечно она очень ,очень дорого ! Работа отличная .
Can I pull the prop off, Toto change the seals without disconnecting the lower unit?
thanks for video
love it👍
My name is Todd Reali and had a ? About my 40hp mercury 4 stroke . What allows your prop shaft to move in and outward with prop on or off ? And should the prop shaft move in and out at all? Thank you for time and input its really helped me with my motor maintenance. Sincerely, Todd Reali
Is disconnecting the drive shaft linkage the same for a 2006 Mercury 50hp 4 stroke? Having trouble dropping my lower unit to do my water pump.
Does anyone know generally what does this service runs to have done? (Ballpark)
Will it hurt anything on the power head if I remove the lower unit and it is a few months before I get it reinstalled. I came out this morning and noticed that the carrier unit had cracked around the bolts. There was some water in the lower unit when I pulled the drain plug. I drained the gear case and flushed it with some seafoam deep creep before refilling with gear oil. I can't do the repair right now, but thought I could remove the lower unit and store it in doors to keep it from the cold. The motor would remain outside on the boat for the winter.
Would love some more info on larger 2 stroke engines. Have a mercury myself and I always thought information would be easier to find
If the prop seal is bad will the gear lube leak out just sitting not running?.. thx
Is it normal to pull out the prop shaft easily? I was able to pull out bearing carrier without any issues but i can’t seem to pull out the prop shaft. Is there trick to pulling it out?
Help with stubborn Mercury 3.0 225 prop shaft seals removal.
Which direction does the inner seal go in
Loctite 271 is supposed to be heated to 250 degrees to remove bolts. I never tried it so I don’t know. How do you get them out if you have to replace the seals in the future?
Exactly! If you're going to use thread locker use the low strength version, 222MS, purple.
Same install on a 2011 4 stroke 60hp efi???
Great video John. About to do this on my 2012 Merc 50hp EFI.
Can the bearing carrier be pulled out with a just regular jaw puller?
Vise marks on outside, how much trouble am I?
Is this the same as a 25hp mercury 2008
Does it mater which loctite you use on the seals
dont use loctite on seals, if you must then use blue!

i cant believe this man put red loctite on the seals and bolts... feel awful for the poor fella that has to work on this LU next. SMH!! red requires heat, blue is removable.
