Out standing, Happy New Year!! 2021 is going to be great!! For everyone. Let me say this , my farther was rated top 100 in the U.S. for Mercedes, as a Mechanic.. and he always teaching his kids to strive to be the best. I feel he would not only appreciate , his son watching and learning from your videos but he would be proud of the professionalism that I would be learning from the video. Thank you for that, Be safe, and again Happy New Year!!! Robert.
Happy NY!
Awesome share, wish I had more mechanical knowledge..thanks for visiting.. New Friend 🔔👍
Thx, I have never pulled one of these apart and may never do it now. An engine rebuild seems easier to carry out.
Some things are best left to the experts
I need one of these videos for the shimming of a classic omc gearcase.
Great vid very intricate job having the right tools makes life easy but a DIY at home wouldnt necessarily have all that is required its then understood why marine shops charge so much.....
Thank you, yes, once you get into doing projects like this, it really isn't a DIYer.
At the same time, it is possible to do all of the seals. It only gets tricky when it comes to tightening down the spanner nut :)
Marine tech makes one of best carrier pullers I ever used
I don't think I've ever used a Marine Tech tool that I didn't like lol never used their carrier puller, but I can imagine it's top of the line!
You my friend made that look too easy
Well thank you!
Re shimming a gear case is no easy task, thank you though this is a really informative video at least I have a good general idea of what is entailed in doing a big job like this. Think I'll leave this one to the pros!
No kidding. I think I'll just buy a new lower unit.
Thanks. Extremely helpful, for the future.

Your welcome! Thank you for commenting :)
Great instructional video. I may pull my powerhead to do some maintenance!
Lol :)
My dear brother you made the video very helpful, please make once more details slow video, may be 15 minute 20 minute, no problem.
I see now. Thanks. Trying to change my drive shaft on a 5.4 gear case. 300 verado 09 model. 25 inch shaft.
Good luck!
Merci beaucoup ❤❤❤❤❤❤
Any videos on how to shim / set the backlash on a lower unit
U can use a propain tank small one a lot of carrier get stuck bad from salt water corrosion so use the propain heat the lower until up all over do not keep in one spot and it will expanded and will release the carrier hope this helps ya .x marine tech
Since you have the lower unit so far apart, would you mic the gears to check for wear?
Why not replace the needle bearings with the unit apart?
Why were the other bearings not packed with grease?
Does everything only go back together one way as not to put anything on backwards?
I really enjoy youe videos, I've learned so much! 😀👍🏻🚤🔧
You could mic them, I'm not so sure that it is necessary though :) The needle bearings weren't worn out enough to justify replacing and you don't want to pack gear case bearings with grease. Instead, you want to put some clean gear lube on them and then install. Yup! Everything only fits in one way :) you don't want to change the preload on any of the bearings. Thank you very much, glad they have been a help to you! Thank you for all of the comments :)
@@BornAgainBoating Good to know, I'm often torn when taking something that far apart if it isn't worth it while since you are there just to replace wearable parts.and be done with it.
Very informative 😁
Very good video. I have a lot of experience with bravo stern drive the easiest way to remove a bravo prop shaft carrier is by just getting small aluminum scraps more or less about an inch tall and build them up around the prop shaft, of course this will all have to be taken down before the carrier is removed from the case. Then with old bearing races or similar build up to the threads of the prop shaft and use flat washers and a old prop nut with no nylok. Tighten down till movement making sure not to bottom out on the spine. This will only work with bravos that shift in the upper. I have never tried it with a bravo3 that’s not a performance drive just bravo ones and two’s
On my Bucket list. Lower unit Full Service. Getting little water since I came from Marathon
just did mine and its much easier than anticipated
Nicer sticker on that snappy box. (info wars) 👍👍👌👌
Thank you lol ;)
What puller tool did you use in this video? It looks really versatile.
Why skip the re shimming process? That's what most DIY folks need to see. Very IMPORTANT step to skip. But I still like watching your videos.
Yes u r right
Can you make a video on shimming the gears?
Thanks!
Do you have a video on lressure testing a lower end? Also do they vacuum test them too? I know some seals are fine under pressure but when a small vacuum is applied they leak. And by small vacuum i mean as little as a good heat cycle may produce.
No, we don't have a video on pressure testing the lower, which would be a good video. You can vacuum test them, but I haven't vacuumed a gear case for years now! They absolutely could leak under a vacuum from a heat cycle but generally gear cases today are pretty solid, and if they hold 12 PSI then you don't normally see any issues.
You make it LOOK SIMPLE 🤣😃😁😁
Lol, you will be fine, they aren't that bad, you don't need to disassemble it down this far though lol
@@BornAgainBoating just passing by my friend. Gas Tank on my Boat coming along Great. See you Soon. @ mahimahiaddiction
my brain just exploded.
thanks i think,:)
Hi. Excellent videos,
I'm looking for the same lower unit , 5.44, counter, 30" shaft, 1.85.1, gear ratio with small propshaft.
Thanks
Don't know of any one right now
Super strong
"The lips of the seals facing away from each other" Please explain how to remember which way the seals go in.
Slide hammer , with bearing adapter , won't work as well as a puller but the parts store will rent them
Watched a video of a guy using a air chuck hooked up to the fill plug of the lower unit to blow it out.
Thanks for the Video 😃
You're welcome! Thank you for commenting!
When changing shaft length on the Verado, looks like you also have to change out the upper shift shaft. Do you have to pull the power head to replace that shift shaft, or can you get to it by getting some things out of the way?
Yes you do, but sadly no you can't, youve gotta pull the powerhead :(
Used an axle puller to pull reverse gear
What about the shift shaft
Am following your video, got to pulling the gear case out but only the front part with the fins on came out, (i have the 3 finned carrier)so the rest of the carrier with the bearings and all must still be in the case. Do you have any recommendations on getting the rest of the carrier out please or a video link to this situation?
are you for hire or can you refer me to a shop in south florida? I need this job done and I've had nothing but bad luck with trades.
Hi.. I like the content of your videos. I wonder if you are in South Florida my any chance? If so, I might need you to take a look at my lower unit.
Hey! Yes, I'm in the keys but I don't really do side work. What's going on with your lower?
Hi. Thanks for your reply. I hit a rock and I bent the prop while I was in KW. However, I noticed after the fix there is some vibration in reverse and not that obvious in forward as well. When I got home I observed the lower unit is got some type of metal sound when I put engine in gear. Not sure if this is something to be concerned about. After wall I hit the lower at WOT...
Ouch! Yeah, that will do it :( Um, it's hard to say without looking at it. If you had it repaired by someone reputable and they tested it, you should be good, but at the same time, like you said, when you hit a rock at WOT sometimes you can do your best to fix the lower, but it could just be so out of whack that it can't be. Do you have any kind of warranty or insurance?
GM... My standard warranty expired three years ago; however, I still have Y.E.S. warranty coverage till November of this year. I believe this warranty covers major parts, etc. Do you think I can use this warranty to get this looked at/corrected? That would be awesome!!
@@marlonm396 oh, idk, that's pretty far into it. Sometimes Yamaha is nice and will cover some things, but they can be stlickers too. Normally, that's not really a manufacturer defect lol but it doesnt hurt to ask :) they will probably tell you no way, but that's not going to be a shocker. I think your engines to old for them to be nice about a ground strike :(
Are you located in South florida I need work done to my lower unit.
Hello BAB!
Great video! I have successfully gotten the carrier (has 4 of the supports like yours) out of my lower unit but I can’t seem to remove the gear from the carrier like you show in the video. You simply turned it until it comes apart but mine just spins and won’t separate. Is there some kind of keyway that has to be lined up to be pulled apart? I will note there is some space between the gear and the face of the carrier along with a large washer/spacer in between that is loose.
Any help appreciated as I am now stuck! Thanks! 👍🏼
@born again boating Hello again, any tips on how to get the gear off the carrier?? Thanks!
So I've watched a lot of your videos and find them usefull. ATM I'm haveong a few issues getting my pinion gear of l and can't get my dog clutch to alignment any help would be appreciated
Where can I get a puller like that? Thank you!
That was a Snap On puller but they are super expensive, here is a Marine Tech Tools Puller and it's a lot cheaper. I have this one as well and it works great just like the snap on one: amzn.to/2WsfX6V
Good video
Thank you!
Great! Do you have a video about Johson V6 lower gear? thx a lot
That we dont. Sorry
@@BornAgainBoating are them becaming rare or not existing anymore?
@@BornAgainBoating thx from southern Brazil
Where can I get that carrier bearing nut removal tool? I’ve been searching like crazy with no luck

what kind of boat is the small one in the intro please and thank you

Hello, is the merc torque master 2 much different than this teardown?
I'm not sure. They should be fairly similar. But they are different gear cases, its best to have the right manual with you whenever you rebuild a gear case :/
Born Again Boating . Tore the TM2 today and it’s practically the same. The only main difference was this one has 18 needle bearings instead of the 21. Thank you for making this video.
You didn't need to take the shift slide apart .
Hey what’s the part number for the snap on jaw puller ?
I'm not sure what that one is. But this one is from Marine Tech Tools is what I'm using now: marinetechtools.com/lower-bearing-carrier-housing-puller.html.html
So why was it a "rebuild"?
Had to change the driveshaft from a 20" to a 25", so it had to be reshimmed and new bearings :)
👌🏻👌🏻👍👍 I subscribed
Awesome! Thank you so much!
How do you do everything so flawlessly?
Lol I wouldn't say I do things flawlessly lol it's all in the edit! lol
