Rebuilding the Gimbal Housing and Bellows Replacement

In Today's video we Rebuild the Gimbal Housing on my Mercruiser Alpha I Gen. 2 outdrive. This is very similar to the process for Bravo drives as well.
We Replace all of the bellows( U-joint bellows, Exhaust Bellows, and Shift-cable Bellows), replace the gimbal bearing as well as the Water hose and Oil Line. We also repair the speedometer tubing and trim sender wires.

Since I tuned into your video to learn how to repair my 2008 Tahoe 4.3, I have nothing but praise for your work. I have followed you step by step, simply pausing the video while I completed your example. I did watch the entire video from start to finish before attempting this job, so I was aware of the couple of corrections you made in the beginning. KUDOS to you. My stern drive is just about ready to reinstall. I had purchased a rebuilt engine ( block cracked last February during hard freeze in the Dallas area. My fault entirely for not properly winterizing ) Anyway while I had the engine out , I decided it might be worth checking the bellows etc and service them at this point. Very good choice on my part. Thanks for a great instructional video.

[@BretANewman]

Bravo is all I can Say! Great Attempt and Great Advise Followed from one who has confidence and is not afraid to pass on a tip or two of Knowledge.

[@mastershakebmore]

Great video! Couple of things I noticed thought, you don't have to put bellows adhesive on the u-joint bellows where it meets the bell housing, the retaining ring seals that end. Only need it where it meets the gimbal housing where it's secured with the hose clamp. You DO need bellows adhesive on the shift bellows where it's attached to the gimbal housing. Also, you should use perfect seal/Permatex aviation form a gasket on the speedo fitting threads.

[@Thewrightstuff777]

Really cool job! I’ve seen how doing gimbal work is difficult no matter what brand it is. And they ALL have “special” tools that are often pricey.

[@SmokedTirez]

Every niche has special tools especially jetskis,motorcycles and cars/trucks planes etc but basically thats why marine mechanics get paid what they do and when you do a few jobs with the tools it usually pays for itself after that in rewards. The tools alone needed to do the job let alone the technical knowledge of how to do it step by step to get the tasks done quick n efficiently is what you pay for..Sure theres Marinas with shoddy mechanics and thats because they cant pay a real marine mechanic what hes really worth and stay in business so they settle for hit n miss diagnosers or as I call them second rate parts changers that surprisingly generate money too when they hook the golden whales with deep pockets that want to get out on the water.

good job. slide hammers may not remove gimbal bearings successfully. better to have a threaded puller where the nut will steadily draw the bearing out. And at 19:00, you definitely want that special tool for the bellows retaining ring. You'll destroy the ring with anything else. Also, the bellows adhesive is a contact cement type glue so you want to let it set up a bit on both surfaces before assembling the parts.

[@thomaseckelkamp3053]

I forgot to place the Allen screw on the end of shift cable . I know I probably didn’t have to remove its, but I did. All in all a great video .

[@fritzc.9700]

I wanted pop back in and add in my challenges and solutions in case anyone else runs into the same. I have a V8 with a removable cover, but seats on either side. So reaching back to the inboard side on the transom is VERY difficult. I did all work with the engine in place. - I should have snipped the gear lube line before trying to remove the bell housing because I broke off the plastic fitting on the gimbal housing. The fitting is attached with an E-clip on the inboard side, I was able to remove the original clip with a long screw driver and bore scope coming from the Starboard side. Installing the new one was tough! I tied a string to the new E-clip because it got dropped a hundred times while trying to position it in the groove. Once I got it located, I taped a washer to my finger tip to push the clip in place. I did the install from the port side, and yes, the string is still there. - Installing bellows to the bell housing: I had a piece of 1" wide x 1/8" thick aluminum flat bar, about a foot long, that I bent ~100 degrees around 3/4" from the end, then I rounded and smoothed the bent end. This was great at grabbing the inside convolutes on the bellows to get them in place. I installed the driveshaft bellows ring by first lubricating with spray degreaser (like simple green), then I found a tin can in the garage that happened to be the perfect diameter and used this with a dead blow hammer to tap it in place. This all went very smoothly. - Lower shift cable install: I had a tough time getting the sheath through the transom and under the engine/manifold. It has to take a sharp turn right after passing through and this was a 2 person job using various means to guide it around. But when I went to put the core/cable in the sheath after the bell housing was installed, the solid cable end was too stiff to pass through this tight bend area. I had to unscrew the sheath fitting from the bell housing while holding the greased boot with a pair of vice grips so it didn't twist. Pull it out about a foot, then push the core in as far as it would go, then push the sheath and core together past the tight area. This worked great, but then I couldn't use the special socket to reinstall the sheath fitting to the bell housing because the core was in the way. The fix was to grind a slot in the special socket so the core could run through the center, then use an open end wrench to turn the socket. In the end, everything came together and no more leaks! Good luck to those getting ready to tackle this. It's not too tough if you follow good videos like this and take your time.

Hey Doc, can you confirm to me that the shift cable housing on a bravo 3 is pressed in from the back? I need to replace mine but upon inspection of the bellhousing and current cable installed I cannot figure out for the life of me how to get the brass threaded housing out of the bellhousing as the nut on the back is locked in via a metal form molded into the bellhousing to stop the nut from turning.

After pulling the drive shaft bellows into the bell housing grove (I did add glue in the grove as you showed) I can not get the metal retainer ring to drive in, I do have the proper driver, would it be ok to add grease to the ring so it will slide in?

Should be ok to use grease, just want to make sure it's not able to slide back out

[@csamf]

New to boating and have an old beater. Someone spotted a tear in my exhaust bellow. I tried to replace it without taking everything off, but no luck. I've been still taking the boat out with it just attached to the boat side. My question is, because it's the exhaust, does it HAVE to be connected? Will it let water into the boat if it's not attached?

[@ZachsGarage1]

Short answer is that it should be fine. The exhaust actually comes out of the sides of the gimbal housing anyways. The exhaust bellows just helps route some of the exhaust to come out of the outdrive where the propeller is

[@user-iv7jp5kg9k]

With the Alpha Gen one which does not have the insert that attaches the U-Joint bellows to the bell housing it is necessary to put the bellows on the bell housing first and then slide the unit in. Its really a pain.

[@JKURR]

I’ve traced a gear oil leak coming from the oil line. Do you know if this can be replaced without disassembling from the housing? Meaning, just undo it from inside the boat as you showed then pull it out from outside?

[@ZachsGarage1]

Probably not, because you have to re attach the new line on the inside of the bell house piece I don't know if you have enough space to get to that, you can certainly try though

[@nickvlassis7496]

[@irredeemabledeplorable5227]

just a little FYI....when replacing hoses, especially the WATER HOSE, it is important that you not install it TOO LONG. In the lowered (running position) it WILL kink and pinch off water flow which will cause an overheating condition. ALWAYS operate the unit up and down fully to ensure the components travel freely.....oh, and that bellows tool is worth it's weight in gold......unless you don't value your time.

[@kevint8886]

Zach, in the middle of my first alpha 1 gen 2 rebuild. Must have watched your video 10 times by now. thanks! i have the Gimbal bearing installed but can 't convince myself its in all the way. is there some kind of measurement basis, like the depth of the them groves on the side ? or anything. should the back of bearing be inside the seal ? i can feel a space with my finger past the bearing... just freaking out. sorry any help appreciated. thanks again

[@ZachsGarage1]

Well the way I knew is I couldn't get it to push in any further. If it's not budging despite your best efforts then it should be fine. I believe the drive shaft has some tolerance of surface area for the depth the bearing touches on it

[@kevint8886]

@@ZachsGarage1 thanks, i'll push ahead and see what happens.

[@walliisch]

But with it mounted on the transom and engine installed you wouldn't be able to remove the gear lube hose like you did by removing the whole thing from behind. And in that case which order do you find easiest, attach the gear lube hose on the gimball housing side first then the bell housing or vice versa? In both scenarios it's gonna be real tricky to install cause of the tight space and short hose. Would really appreciate you opinion on this.

[@ZachsGarage1]

I think you have to unscrew that metal nipple/coupler (shown on the table at 12:50). I don't think I could have done it without doing that. You can still unscrew it and remove with it on the boat and engine in. Just remove the hose from the oil reservoir first and remove that hose on the inside going to it first

[@walliisch]

@@ZachsGarage1 In my experience that would be next to impossible to access with engine installed. Or at least even more difficult than doing it from the outside of the boat. So that would be my 3rd option 😅 But let's say for argument sake that removing the whole insert from the inside was not an option, how would you proceed in that case?

Hmm, I am not sure, I noticed the slots only being on one side, there was not any mention of which way it should be turned from the manufacturer when i ordered mine.

Don't use electrical tape on wires exposed to liquid it's terrible for that. Use 3M tape that bonds to itself when stretched, it uses no adhesive to bond it seals by chemical reaction and is rubberized for a nice water tight seal and good durability. The 2 X 4 tip though is a good one but you also could have raised and gently dropped the outdrive to use it's own weight to pull it from the gimbal like a jackhammer, I choose to utilize the 2X4 piece myself if my outdrive even works on the boat I acquired, I've yet to evaluate the electrical fully but I know there is issues with that.

Hi. Great video. One qestion. I am changing bellows on my Sterndrive, but I didn't konw about the metal clip on the back on the below (U-joint) as you show in this video. Are they important, or can I continue without it? What is it good for? Hope you can help. BR John

[@ZachsGarage1]

Well John you can always continue and try anything.... At least one time 😉 But here are my thoughts on the metal clip. The clip helps the bellows not slide off. The metal in the clip flanges out to provide more friction. There will be plenty of people that tell you have to follow the book or disaster is going to happen. You might be ok without double checking it but you would want to keep an eye on if it ever starts to slip off and removing your outdrive to make sure no water is getting in the bellows anyways

Her I have to fastned it with the metal ring, that is pressed in. My question is: On the inside of the bellows there is a small groove, but it is too small to fit on the edge of the gimbel.Therefore, I expect it to be peeled in, and the edge of the gimbel should be behind it so that there are two flat pieces with the small groove in the middle inside the gimbel before the metal ring is pressed in. Is this correct? Br John

Hi, those little metal clips are there to keep the hose clamps grounded so they do not corrode. I believe it's called electrolysis. That's their only purpose, the bellows adhesive is what keeps them from slipping off. Mercruiser manuals want you to wait 10 minutes for the adhesive to get tacky before installing fyi. If you boat in fresh water I wouldn't worry about the clips.

@@iWatchVideosAtHome Exactly.... and if you trailer your boat home every time, salt o5 fresh water, discard the clips,they are hard SS and they have a dimple that digs into the aluminum,destroying the protective paint in the process; a " rushed" solution from Merc, but by far the simplest and trouble free one at that.

My god, that looks complicated! But it is necessary to replace the bellows every now and then. My buddy 1997 Bayliner sank in the harbor because the big bellows had burst. so during one night the water filled his boat. it cost him a small fortune to fix everything. I don't know in the US, but insurance here (Netherlands) didn't pay out because it was a lack of maintenance …But I'm so NOT looking forward to start with this major job.

It is quite the undertaking, but most of the individual steps are not too difficult. That sucks about the insurance for you buddy!
