You have no idea how valuable these videos are to us,, or maybe you do. Thanks again. ❤
Good morning, that means the world to us. Many more helpful videos to come, we promise!
😎👍
Wow! What an incredible video, don't think I have seen anything as well delivered as this. Thank you.
That means the absolute world to us, thank you. 😎👍
I mean, for f*ck's sake this is a brilliant video. This is what happens when an engineer rebuilds lower unit. I don't know much about the actual rebuild process (which is why I stumbled on this video), but - if anything - this video shows the value of having an impeccably clean work area. This dude's doing this rebuild in a carpeted room! Excellent video, Michael!
What’s up Bill, very kind of you to share. Carpeted room indeed..🤣…and wife approved.
I looked at her and said…”but I’m mean…it’s kinda for the business…”
She gave me the green light! 😁

This is a fantastic series. Covered so many details. The only questions left unanswered is end play and gear patterns/shimming.

This is the best and most complete DIY video I've ever enjoyed. with all worst case scenarios! Awesome job! Thanks for taking the time to do this amazing video. subscribed for sure.
Thank you, that is extremely kind of you to share, and we are truly honored to receive your feedback. Please reach out to us any time, we have a lot more videos in the Que that are set to release soon. 😁👍
Awesome video, question? Why not try a little heat on the retainer nut before drilling it?
@@mattbob6350
Thanks for watching, we appreciate it. Great question and you definitely have that option.
Most important thing if choosing heat is to ensure you don’t burn yourself nor damage the outdrive case.
Heat can be an incredible tool in DIY projects like this. 😁👍🧰
I agree these are the best comprehensive videos along with excellent camera work. I reinstalled a bearing assembly and did Not put 210 lbs of pressure on the torque and put oil in to check leaks and it was bubbling through as I looked down into the cavity. Will the torque of 210 lbs solve this problem or need I look elsewhere? It is seated all the way in.
Good morning, just poured a cup of coffee and am sitting down to answer any and all questions for the DIY community.
This means the absolute world to us, thank you for sharing this. Applying the 210ft-lbs to the retaining nut should definitely help seal your lower unit. Please keep us posted, we are always here to help!

@@DIYwithMichaelBordersHi Michael. Thanks for taking the time to respond. Good to hear your boat is back in the water, you did a great job.
My boat has twin Mercruiser 3.0 litre engines on Alpha One Gen 2 out drives. They run in opposite directions. I stripped the boat over winter for renovation work, but fear I may have put the drives back in transposed positions. I have since lost forward drive on one side and the gears are grinding. Apparently, Alpha One's have weak reverse? Have you or any of your community heard of this? What could have broken?
@@willdavis3332
Thanks for the reply, haven’t worked closely with twin outdrive setups in the recent past. Is it more of a humming, rattling, or knocking sound?
Weak reverse can be as simple as a friendly adjustment to your throttle cables.
You’re spot on though, alpha Gen 1(2) drive reverse has never been incredibly responsive however it has always got the job done.
@@DIYwithMichaelBordersI would describe it as quite a rough, grinding gears sound. I did try disconnecting and directly operating the shift cable which goes to the outdrive and it won't hold in forward gear, just makes the noise. So I suspect damage to the gear components inside. Could be a dog clutch problem from what I have read. Looks like I may need to dismantle lower unit as you did. Your video will be a massive help, thanks again Michael 👍
@@willdavis3332
Thanks for the quick reply, taking apart lower unit will be best. Getting the lower unit cleaned up with new seals and bearings will hopefully be all you need…however if you find any imperfections or damage to the gears, you will want to replace those as well.
Hello I love your videos, trying to help a friend out with his 0F239081 alpha one gen 2 water tubes were completely destroyed and going to replace but I can’t locate the tube for the speedometer. Not sure where it is but must’ve broken at some point by previous owner. Do you have any info on it
@@cRaZyCroCe
Thanks for watching, any update? We can definitely help. We will need your outdrive serial number so we can provide you with the most accurate information and location.
You can also insert your serial number into:
www.marineengine.com/
You will be able to pull up all schematics/diagrams for your friends outdrive.
🧰
This is way over the top for a DIY and I doubt that even a single person would try this unless you are a Mercruiser mechanic in a repair shop. The mechanic’s fee for a job like this would probably approach the cost of a new outdrive. I would rather buy two new outdrives than to even attempt a job like this.
Good morning ☕️

This is a DIY video. It’s not over the top for anyone who enjoys a challenge and likes saving money with their mechanical talent. The only thing over the top is your asinine comment. You probably work for Mercruiser.

Awesome set of videos
Good morning ☕️ very nice of you to say, thank you. Hope you are making good progress with your project.
Merci beaucoup ❤❤❤❤❤
Do you have a video on shimming the upper and lower gears? Whithout shimming after installing new gears and bearings it could lead to a catastrophic failure.
Thanks for watching, you are spot on. Following your exact serial number service manual for the shimming process is a must.
We don’t have a video showing shimming at the moment.
Place the water pump key on the shaft then slide the impeller down the shaft and Seed it onto the key. Then take the housing and as you slide it down on top of the 77th on top of the impeller turn the shaft that will make the impeller go up inside the housing much easier than doing it the other way
Thanks for watching and sharing your advice. 👍
Any videos on doing the upper unit?

We’re you taking the bearing carrier nut off by turning c-wise or cc-wise? Do you have an approximate cost for everything you replaced? Great video btw.
Thanks for watching, we removed bearing carrier retainer nut by turning counterclockwise.
If you don’t already own the required tools, you can plan on spending roughly $2k after all said and done with brand new OEM parts.
Most will sell their tools on eBay at the end and get a few hundred bucks back however we keep our tools for our next set of DIY videos for the community.

Thank you. My manual indicated CCW and the nut indicated as well. 2 grand.. ouch… A grand over what I bought it for when it was running. Guess ya gotta pay to play if you own a boat. Keep up the good work on the videos.
@@maddogschannel9857
That’s for OEM parts which we always personally purchase…unless the specific OEM part is no longer available.
Aftermarket rebuild will be hundreds of dollars cheaper.
Sweet video. I bet my wife wont allow me to build mine in the spare bedroom lol.

@@rayjohnson1778
Outboards always perform in a uniquely different manner when out of water as we have all leaned. You may need to adjust your shift cable or it might need a new lower unit prop shaft gear and clutch-dog.
Hi, Michael thank you for these great videos, do you have a link for tools and website to purchase pdf for my engine and outdrive, i am new to boatting and youtube appreciate your Great work

What is the name of the tool at 29:47, also where did you get your manual?
@@CustomGraphixWoodworx
Thanks for watching, this is the Pinion Gear tool. 👍🧰
Assuming the diameter inside the lower unit is about 3.5 inches and putting 25 psi inside would only give you a pushing force of about 240 lbs. I doubt that would be enough to be of much help. However the hissing was helpful since you knew you were loosening the carrier. Good result anyway.
We appreciate that, we hope your DIY project is going well. ☕️🧰
Put steel plate on where prop goes and bang on it an walk around an it’ll pop out no need to do all that drilling 😊

How much would you charge to do this job

Good morning ☕️
As far as quoting out a project like this…you will find that most marinas will have the same if not very similar prices…roughly a few grand high end…🤔
The trick becomes finding the right marina that will to do it right with OEM parts and not over-charge you. Keep us posted on what you find.
I mean all these bearing carriers requiring so much force to pull out... why even bother with the threaded ring and high torque??
@@BlackoutBilll21
We definitely understand your thoughts, they can be stubborn to get out.
Michael I have the same problem with overheating and the copper tube came out with the lower what did you call the plastic melted housing up inside the upper unit? I am tempted to torch it to melt remaining plastic as the bolts are not accessible now due to melting...did you ever figure out why your unit overheated with a good impeller? thermostat? clogged risers or lines? good work showing all the gory details!
Good morning, just poured a cup of coffee and am sitting down to answer any and all questions for the DIY community.
This is the Water Pocket Tube/cover. Heat gets the best of that part. Keep us posted on your rebuild.

Thank you for awesome manual! That is your opinion about SEI aftermarket outdrives? My one has broken main gear pinion 2 months after slow RPM stone bottom colliision

Thanks for watching, that doesn’t sound fun. Did you fix it?
@DIYwithMichaelBorders no, I'm getting ready to pull out a bearing carrier
@@TheBaza1978
👍
@@DIYwithMichaelBorders you didnt answer about SEI (
@@TheBaza1978
Thanks for the reply, we find that SEI is a great option.
I have a 1978 boat with a 350 in it, and I believe a 228 Mercruiser outdrive. I am wondering if you would be interested in me hiring you to go through it for me?
Thanks for watching Alan, we stay busy in a great way here at the DIY Raptor HQ.
Did you end up rebuilding your outdrive and if so, how is your project going?
Use a slide hammer and pull the prop shaft out
Where did you get that lower unit stand?
mike, had my lower unit replaced 2 seasons ago with used lower they said they pressure tested it. this fall i decided to check for water and was half full with water,,,? what do you think my leak problem would be?
Good morning ☕️
A few things come to mind. Do you notice any cracks on the lower unit that would allow water to sneak into case and mix with gear oil? If so, you would unfortunately need a new lower unit.
If no cracks, which would be a good thing…check to see if your flathead screw that secures into lower case (where you insert gear oil) is not loose or damaged. It may be a great time to install a brand new gasket on that flathead screw to help create that watertight seal.
After that, direct your attention to the prop area. We recommend removing your prop and inspecting the internal bearing carrier and seals. Below is a link to our video showing how to remove prop.
th-cam.com/video/rx1uXhE2Kdw/w-d-xo.htmlsi=7yxKHefPtSLluA64
If you see any signs of damage or fishing line tangled inside bearing carrier…chances are water is leaking through the bearing carrier seals and into case.
If that’s what you find, we recommend removing bearing carrier and replacing seals. Please keep us posted.

i did not see any cracks,,, i will inspect prop shaft in spring, boat to storage currently. thank for help. Art@@DIYwithMichaelBorders

Thanks for the vid! Any on the gen2 alpha? My shift shaft slides up and down and makes it chatter when it slips down. Don’t know what i did.
We appreciate that, thank you. Don’t have any videos on a Gen 2 at the moment however you will find it to be very similar.
We will always be here to help answer questions. 😎👍🧰
Thank you! It is similar but it has an arm on the lower shifter instead of a top-spline dial. I can’t get it to not slide up and down.
@@trojanwood
Thanks for the reply, a DIY rebuild may be best. 😎👍
So, at the end. are you setting the upper and lower unit in forward gear before assembly?
Good morning, just poured a cup of coffee and am sitting down to answer any and all questions for the DIY community.
You will want to carefully align the splines of lower unit shaft extending up and the lower splined cavity of the vertical gear installed in upper unit.
Additional items will align in a friendly manner as you carefully connect the two units.
Below is a link to our video showing us connecting upper to lower.

The spline shaft on my lower unit sinks a little and has free play in the top bearing, does that indicate a rebuild is needed?
Thanks for watching, are you referring to the Drive Shaft that feeds up into the upper unit or the Prop Shaft that feeds through the bearing carrier of the lower unit?
@@DIYwithMichaelBorders I believe he's referencing to the Drive Shaft retainer, bearing and race that feed up into the upper unit @ 1:25:00 I have a similar issue, where there is slop between that bearing and Drive Shaft. My question is, is this normal? Thanks. P.S. Love the videos

Referencing the drive shaft, retainer nut, gear and bearing…once everything is put back together and properly torqued, yes…there should be an ever-so-slight amount of play present when pulling up on the shaft. 👍

What's the proper gap between the dog clutch and pinion bolt please?

@@DIYwithMichaelBorders thanks, I am only just starting, but can't get reasonably priced tools in the UK, so trying to figure out if I can set pinion height without the merc tool - I am now thinking gear marking compound to get it right, which surely would work??

Wood you happen to know What would cause gear oil to leak out of that little tiny wep hole on side of case I believe that little hole is used to drain out water but it’s leaking out oil
Good morning ☕️
Great question and we appreciate you asking. That indeed is your drain port to drain all your gear lube out of your outdrive.
Behind that screw is a gasket. The gasket helps create that watertight/oil tight seal to prevent any gear lube from leaking out.
Over the years, the gasket fails and begins allowing gear lube to leak out. Replacing that gasket with a brand new gasket will solve issue.
Keep in mind after you remove that screw, it’s best to fully drain outdrive followed by installing new gear lube.
Below are too helpful videos showing those two procedures.

Sorry, I’m talking about the little tiny weep pole on the right side of the case not the drains screw if you’re standing in front of the prop, it’ll be on the right side of the case I got oil leaking out of that
@@mikemoreno7329
Thanks for the reply. Was the outdrive recently serviced? Possibly too much gear lube put into drive and an internal seal has failed and oil is now mixing with water as it is streaming out of hole.
The weep hole is specifically designed to drain water from drive cavity. If outdrive cracks or seals fail, oil can sneak into the cavity that water is extracted from.
@@DIYwithMichaelBorders boat was in storage and when I took it out, I noticed oil was leaking out of that little hole hasn’t been serviced for a while hasn’t been on the water I’m guessing, possibly carrier, bearing seals or shift shaft seal thanks for your quick response. I watched all your videos very impressive. And detailed. 👍
@@mikemoreno7329
Thanks for the follow up. Honestly, bearing carrier seals are likely the failure point causing gear lube to drain out of the water weep hole.
If you have an alpha one Gen 1, it’s gear lube. However if you have a Gen 2 or bravo drive, you have the additional oil hose feeding through hull and into outdrive transom.
Please respond ASAP thank you in advance.
I had a guy do my bottom end he said the ring was inside and he could get it to go back together without removing and reinstalling the ring onto the shaft... is this true or should I be considered? New to the boat world please be gentle with me lol...
Thanks for watching, that’s very possible depending on the age and overall condition of the internal parts.
At any point if the lower unit allowed water into areas that it’s not supposed to be…well…bad things happen.
Is your lower unit connected back to the upper unit?
@DIYwithMichaelBorders I took it off and put a new one on. Luckily, he had it pinched and it definitely would have leaked.
@@chrisjusta3655
Thanks for the follow up, great job. If pinched as you mentioned…it would have failed fast.
Awesome job! 😎👍🧰
Question, at th-cam.com/video/qxvL_KgO7ho/w-d-xo.html (1:42:43), you mention lubing the inner seal, or top portion of the impeller. My impeller kit does not have a seal there, nothing between the plastic housing and inner steel impeller sleeve. Is my kit missing a seal? It looks like there is a pocket for a seal to go there. Does anyone know?
Good morning, just poured a cup of coffee and am sitting down to answer any and all questions for the DIY community.
What year is your outdrive? Is it an Alpha drive? It’s possible that your serial number outdrive has a slightly different designed part however unlikely.

Michael, I am wondering what year your lower unit is. I am rebuilding my 1990 and the drive shaft you have, has a grove for a O ring on the shaft. The shaft I got does not have the place for and O ring to go. Does it matter if I have the O ring or not?
Thanks
Steve
Thanks for watching Steven, ours is a 1989 alpha one Gen 1. The upper drive shaft o-ring seats inside the bottom of the vertical gear which is installed in the upper unit.
Once upper is connected to lower, it helps creat additional seal. Keep us posted on your project. 😎👍
@@DIYwithMichaelBorders Thanks, Michael. I ordered that shaft from a Merc Cruiser dealer. Is this the wrong shaft? It says it is for a 1990 alpha one Gen 1. Can I use it? if not will you give me a part number and where I may get it. Thanks
Steve
@@stevenstigall6533
Great question, the best action to take is look the shaft up by serial number. Go to:
Marineengine.com
Scroll down and select Mercruiser. Enter in your outdrive serial number and select search.
Select the lower unit schematic that shows your driveshaft and reference item number in picture. Take that number and scroll down to see the exact OEM part number for your exact shaft. Keep us posted. 👍
where do the shims go ?
Thanks for watching, when installing shims…please refer to your exact serial number service manual. Your drive might be different than ours.
😎👍
@@DIYwithMichaelBorders alpha one gen 1 - 1988 3 l 125 hp
I have 3 small shims and 2 medium and I don't know where they are going
@@user-hj8tg5fq3w
We appreciate the follow up. The larger shims (if the same size as your u-joint and bearing assembly) will be inserted into upper unit and pushed flush to rear lip prior to installing u-joint assembly.
@@DIYwithMichaelBorders
ah ok.. because a mr. I said that shims were needed for the lower bearing gear and for the upper bearing pinion shim at the top for straight alignment
I would have just bought a new built lower end for $1200....lol
