How about repacking a prop shaft on an inboard boat ?

My favorite method, is the one where I bring it to you, and you do it 😂

Nice job again, to keep Murphy’s from entering, I believe I will use the small flat head screw driver instead of the drywall screw method. Thank you for all you do to help people like myself, that has more time than money. You are awesome my friend, Thanks Robert

This channel is so well done and perfectly articulated! Great Job BAB!

I might have a blown seal but I have a 2020 75hp mercury. How can you tell which ones this doesn’t work for?

Nicely done video. Tried method one, could not get the drywall screws to seat into the bearing, even after trying to drill a pilot hole. After over an hour, ended up using a dremel tool to cut into the seal (away from the shaft) and basically tear and pry the seal with a seal puller. Took couple hours and lots of patience, especially the inner seal, but finally prevailed. This job is not for the faint of heart or impatient!

I'll be replacing the seals on my 80 Evinrude 15. After watching this video I'm confident I can do it correctly. I think I'll try the drywall screw method first. And, thankyou for stressing how important it is not to scratch the prop shaft!

Awesome idea with oring in between seals! I never heard that one. There was quite a bend in that shaft 😉

The O-ring acts as a spacer hopefully relocating the seal to a spot on the shaft without any scratches or nicks!

Dude!... excellent job on the video. The drywall screw trick was amazing. I understand the risks, and will probably get a puller to help avoid them, but what an option to have when you can't get your hands on a specialized tool like a seal puller. I really enjoyed your thorough explanation of all of the processes. The clear instructions give me hope that I'll be able to replace the seals on a 2004 Honda 90hp that I recently came by. Wish me luck!

@@BornAgainBoating So I went ahead and pulled the whole bearing carrier. However, I still can't get the prop shaft to come out. What am I missing? Do I need to pull the shift shaft to get the prop shaft to come the rest of the way out? I want to check all the gears and replace the bearings/seals... so that I don't have to worry about this motor when I put it on the water.

On a Yamaha F50 I have used 3 6mm high propshaft seals, instead of 2 factory fitted seals. The inner seal remained intact even if outer two were severely damaged by fishing line or braid. worked great.

I used the drywall screw method ,, I used painters tape around the shaft to protect it and it worked like a champ .. I opted to throw and o ring between the seals just for added piece of mind .. this is an easy driveway fix but ridiculous price at a shop .. thanks man

painters tape ain't going to stop a screw. If you are too close to the shaft the painters tape ain't going to do anything

Really enjoy your informative videos! Going to be doing this to my 1955 15 hp Evinrude. Thanks for making this great video! Just yanked the prop shaft seal this evening. Good thing I did it before taking it out on the water. All the seals are shot.

Thanks bud, I’ll be heading to ALASKA next week, and need to do this! Cheers

Many Thanks for this - just tried the screw driver technique. Wasn't very difficult to just slowly work around and deform the old oil seals in by wedging a small flat head screw driver in between the casing and the oil seal. As Aaron says just be careful not to go anywhere near the prop shaft and orient the screw driver as much as possible so it is not angled towards the outer casing either. Only took about 10 minutes and once the seal is deformed enough it will come out pretty easily (you'll see it start to move). Problem was though I went a little too deep in places when deforming the lower oil seal. So the screw driver came into contact with the steel bearing housing behind the lower oil seal. So this has left a couple of little nicks in that bearing housing. This potentially opens a gap between it and the new oil seals which I guess will reduce the seal efficiency? I just removed any sharp edges on those nicks and pressed any deformation out with the screw driver as best I could but just though I'd warn people about this. Particularly as you can actually feel when the screw driver makes contact with that bearing housing. When hitting the screw driver with a hammer it should sound a little dull and soft when you are between the oil seal and the outer casing. When the screw driver makes contact with the steel bearing housing it will feel and sound rock hard. At that point don't give it another couple of taps like I did and you'll be fine. If you do just make sure you use some gasket sealer as in Aaron advises as even more important and also if there are scratches from the screw driver on the inside of the outer casing.

The flathead screw driver is good. Less harmful to the prop shaft. Great job. What o ring tool kit did you have there in that red box. Thanks for the video.

Thanks for a great video. My first time changing all the seals. I used the screwdriver and the seal puller. I just took my time, the first one took more time than the second one. Do you have a video of changing the upper shaft seals?

When you clean the shaft at 5:35 to 5:40 it looks as if the prop shaft is bent

Clear and concise, very well done

Thanks, drywall screw trick worked great.

Man great video i half to change my seals this video was a big help thank you

Great content! Bought a fancy seal puller slide hammer to be safe and didn’t work so had to resort to the dry wall screw method. Stayed away from the inner shaft however when trying the flat head pry method I went a little to deep and damaged the outside of the carrier bearing lip that the seal sits on.. I believe it’s just there to make space between the seals so it doesn’t sit ontop of the bearing. Do you think I will be alright letting it ride or replace the carrier housing to be safe?

thank you for these videos. Has Saved me a ton of money and time!!

Thanks always for your hard work putting together the informative videos, great job very much appreciated. So you asked which method do I prefer, the easy answer is the one that works lol. I am working on my twin Mercury 3.0 225's replacing the seals. I started with the starboard OB which has the outer seal installed incorrectly. Attempting to drive a screw in the seal was a no go the screw did not even scratch the seal, so I attempted to drive a self tapping screw, and it just danced on the seal. Time for a pilot hole, not a chance and I do not have long tungsten bit too drill straight 90 deg. to the seal case. Adding a center punch proved to be unhelpful with out a long bit. So I moved to the method of taping along the edge no good. 3rd try is the destruction method yes the destruction method as the seal just was not cooperating. Not sure what was used to install the seal but it seems to be fused to the carrier, and the destruction is all that seems to be happening. HELP! How much heat can be applied safely to the carrier and seal case? Can the seals be pressed out if the carrier is removed, need your help.

" I do not have long tungsten bit too drill straight 90 deg" --> Just get 6mm (1/4") Bar and braze onto end of Drill Bit to make a custom extra long extension. Have done this successfully may times.

Good tips I will let you know how it goes. For the seal installation would you clarify the direction of the seals. One side of the seal is open, which way should they face on a mercury 97 225 with a 4.75 housing.

Like the drywall screws. Did that on my front cam shaft seal on a Toyota van .

Last night I gave this a go. I love to analyze the work that I’m going to do. HUGE TIP for everyone that wants to remove everything. I know there’s a proper tool on removing the whole assembly. So I got this idea and it work amazing !. After removing the propeller and the 4 screws or whatever you have. I decided to run a ratchet strap and feed it through the holes. I came back up and tide a knot. I made sure I had a great loop because in between I used a small jack that comes in your vehicles. I jacked it up where I created tension with the loop I created with the ratchet strap. That thing work perfectly and I was able to get the whole assembly. There’s many ways to go about it. Best thing is to not be afraid and do it right.

I just drained the engine oil on my 2021 Suzuki df70 and saw a very faint white in with the oil color. I did hit a rock with the prop. Guessing this might be my issue. Question is, I used the engine for about an hour or two in low RPMS after since noticing this. The white was so light, do you think my engine is safe? Took it to the dealer where they are going to charge me my soul to find out what it is and fix. Any help here would be nice…. Thank you! 💪🏼

You must do motor repair full time. Best videos. So is the driveshaft seal done the same way? I have Etec 40HP 2011. Im going to tear into the lower unit and want to replace everything where water may intrude as oil is milky. Bought it used and apparently they changed the oil before I bought and snuck this by me. Next time I will know that you take the boat out then check the oil.

The tools are sometimes available on ebay and are usually scarfed up pretty quickly if you decide to sell after using. Makes the job super ez!

Shouldn't the seals be installed back to back with the springs opposite each other ? I was taught that one was to keep oil in and the other to keep water out is why they were to be installed that way ?

Do you know if the screw method works on a '95 Mercury 175xri? Or if it won't work, which bearing carrier removal tool I need for this lower unit?

What's best, 2 factory seals with O-ring in the middle; or 3 factory seals ? Can you do both? Just asking.

i was going to do this once but checked up at the last min. Instead i took lower off and took it to a marina they replaced all the seals and impeeler for $180

Best to replace prop shaft seal every so many years or wait for failure?

Always great videos, Always very interesting. What is the theory on facing the lip seals out. The Yamaha LU's are prone to lose oil and to getting water in them? I think that's why someone had installed the inner seal with the lip facing the oil and the outer facing the water. Do Mercury's both face out? Just curious what you've seen to work best. I have a VMAX 250 07 I'm getting close to changing seals on. One lower you show has a grease fitting, how often should you grease it and how many shots? Thanks for your insight.....

Great Question. Why the difference in how manufactures approach sealing the prop shaft. The demonstration video the Yamaha method has the seals facing each other. For the Mercury 2 Strokes the seals lips oppose one another with the lip facing inward for the first seal and outward for the outer seal.

Good and smart tips for changing seals. But isn't it a very crooked shaft, big risk that it shortens the life of the seals? At 5.35
