Bob, I am doing the same job because I have water in my gear fluid. I plan to replace the seal on the shift shaft and replace my water pump while I have the lower unit off. But isn't there also oil seals around the drive shaft underneath the water pump? I'm thinking that it makes sense to replace those seals as well. What do you think?
I also plan on replacing the prop shaft oil seals and the O-rings on the lower casing cap.
When I called to have this job done and I mention the oil seals blow the driveshaft underneath the water pump and they said start with the shift shaft seal because there’s no need to mess with something that is not leaking because if you don’t get it perfect then you still have the same problem. I didn’t change it and my lower unit is just fine after the shift shaft seal and a new gaskets, I was going to change them like your thinking I’m already in here let’s do it but they told me not to so I didn’t, i’m gonna leave that up to you but I did not change them in my lower unit and is fine. Just make sure to line your shift shaft up correctly in neutral when you put it back together
And thanks for stopping by.
Always something to replace or fix, glad you can do the work yourself, mechanics charge a ton now days
They quoted me $105 an hour thanks for stopping by we’ll see you soon
Great idea with the lower unit mount. You can put the impeller on the shaft first then turn the drive shaft clockwise while pushing the impeller housing down. Saves having to line everything up.
I also just clip off that cable tie on the speedo tube and pop the hose of because those plastic fittings are a shocker.
Great idea
Good old creamy lower unit fluid....Definitely the shift seal and since you're in there replace the pump and use a high performance lower unit oil.....Your freshwater unit looks a lot better than my saltwater unit!!
Had it out in the water twice already I think it even runs better with more power
I’m doing the same on my 2009 50 Merc 2 stroke. I got lazy and used a wooden A Frame ladder laying on its sides to hold the lower unit lol
Good catch on that problem sir this video was informative definitely can't run that milk through your lower unit. I appreciate the video I'm trying to find one on the four and 6 hp Yamaha I have an issue we're not just the lower unit period but the actual housing that connects the top to the bottom has a little bit of Play It's not at the lower unit it's higher up where the black seal meets the pivot point I know it needs a little tightening just trying to figure out where to Titan that with my torque wrench
I hate working on outboards... Glad you caught that before it froze UP!
If I didn’t fish in winter time it probably wouldn’t of worried me but I wanted to get it done
@@bobcrappies I am a preventative guy myself so I know how you feel!
You sound like a cross between Ray Romano and Hank Hill lol
@@lockyer72 you’re not the only one that say that I’m familiar with Hank Hill but not sure
Great info Bob.... thanks for sharing my friend... jeff
Thanks for stopping by man I did a lot of research and nobody really had videos on it so I thought I do one
Gday mate now i know your fishing in fresh water but i didnt see you use one speck of grease on any of that unit grease is your friend just a small ammount on the inside impellor housing on the plate around the new rubber gaskets on the bolt threads ect apart from that good video ive never seen oil that looks like that come out of a gearbox id also be checking aroung my prop seals for fishing line as well it will teminate your rear seals in no time and dont forget to grease your prop shaft .
Getter done Bob 🤓👍.
Hi Bob. When you got around to replacing the shaft seal yours just popped out.... Mine is completely stuck. I wonder how yours was magically wiggling free and you just reached down and grabbed it? I think I am going to have to use the drywall screw method.😑
I'm waiting on this seal to be delivered and come across your channel. Good stuff! There's a break in this video around 13:35 that skips explaining how you got the seal out of the housing. Can you share your tips for getting this seal out without removing the housing?
Thanks,
Grge
Thanks for stopping by-that is a very good question. The seal is in there pretty good, I took a small drill bit smaller than a pencil lead- drilled very carefully to relieve the pressure and it popped right out I didn’t put that in the video because you have to be very careful not to go all the way threw the old shift shaft seal, I didn’t put it in the video because sometimes you can work them out By moving them back-and-forth and I didn’t want nobody to do more damage, Hopefully that makes sense and answered your question and I did have to remove the housing.
@@bobcrappies
Appreciate the quick reply. A small hole to give me something to work with is the direction I was leaning; I'd seen someone on another forum mention it. Camp clean up trip on the river this weekend and a long camp trip for Memorial weekend, so I'm hoping this is an easy swap. If I think about it, I'll reply to my own comment and let any viewers how it went.
Thanks,
Greg
Sounds good and good luck with your project, if the shift shaft seal is not too tight you can work it out but if you do decide to put a little hole in it to have something to work with just barely barely go through the top let us know how it goes
@@bobcrappies so it swapped out really easy....didn't need to drill anything through the seal...with a good hook/pick tool, you can get just enough to pull it out....don't be worried doing this repair/swap yourself
Thanks buddy for the great video my friend 👍
Thanks
What a great video
Thanks I really appreciate it!
Thanks for your knowledge. 👍👍
How many strength machines?
Great video Bob! I really loved it. I have a 2011 Suzuki 60Hp and which is leaking oil from the water intake. The only things I have changed so far in this outboard are the fuel filter, oil filter (every year), and the lower unit lub oil. I think it is time to change the water pump and the shift shaft seal as I was told this could be the problem. Do you think my outboard has the same procedure of replacing these parts as per yamaha one shown in this video? Thanks!
I’m not sure but it’s got to be about the same set up and thank you for stopping by
Bob, I followed your video and all work out fine. I bolted the lower to the motor and with the control box in neutral the prop won't spin. tried numerous times clocking the shift shaft trying to find neutral with no sucess. Do you know the correct way to index the shift shaft? Thanks Mark...
I had that same problem because after I got done it would only go in reverse and took a pair of vise grips with a rag on it and slowly turned the shift shaft to neutral and I could feel when it dropped in neutral And then I was fine, Hope that helps
When I took the lower unit back apart I did three clicks Forward neutral reverse and then dropped it back in neutral once I realized where I was then I was good that’s all I did
@@bobcrappies I get no clicks, just spins 3/4 of turn and then I can spin back. Looks like a trip to the shop.
Is it possible to push the shift shaft back down into its seep I’m just wondering if it raised on you when you pulled the lower unit apart or changing its seal, that’s why Its spins freely,
@@bobcrappies Bob, I got it. I turned the shaft all the way clockwise it clicked into reverse then install lower w/ shifter box in reverse. all is fine and on the water again. Thanks again for all your input and video. Mark....
So I bought one that the rod that connects that you said don’t break it it broke what can I do
If you’re referring to the speedometer cable when I lowered the lower unit at around seven minutes in the video, i’m not positive how big of a project that would be. i’m sorry I couldn’t be more helpful of that.
hey!
i managed to mess with the shift shaft on my mercury outboard, now i dont know how to allign it correctly, i tried starting it propellar just spins in neutral.
What should i do?
You got to go back in and turn the shift shaft to neutral go back through my comments there’s a lot of information on how to do it, i’m not familiar with mercury, I would think it would be the same way
When I did this project, I put a rag around the shift shaft and turned it with a pair of pliers, so I didn’t scar it
Also, when you turn it, you can feel forward neutral and reverse when you’re turning put it in neutral and you should be fine
What happens if speedometer cable is not attached above, only at lower unit.v Does it have to be hooked up at both ends or at all?.
Will it cause issues if no installed?
I’m not sure I understand your question as the speedometer cable was inside on this outboard
Hi, thanks for sharing this, do you know what determines the vertical position of the shift shaft? Is the bottom of the shaft resting on the o-ring under the splines, or is it the bracket that's fixed in the bottom cowling? Many thanks !
The shift shaft was not resting on the O-ring although it did take a little bit of patients to get the O-ring out.
@@bobcrappies OK so do you know what stop the shaft from falling ? That would be helpful for what i'm working on!
The shift shaft is mounted to the bottom of the Crowley it’s not gonna go nowhere the only thing you have to do is make sure it’s in neutral when you put it back together
@@bobcrappies OK, sounded like a weird question but i'm designing parts for a system that splits the shaft in two. Thanks for answering !
Geez Bob that makes me think I need to do a lower unit rebuild on my old motor lol How much do you charge?
I wouldn’t charge you I would just help you
@@bobcrappies I like that idea!
Speaking of WALLEYE SEASON! lol
Get you some ringworms will make it happen
@@bobcrappies Lol Do you need any special colors?
Green Ringworms with red flake has been my go to this past year
Do you notice it running better now?
We’ve had it out twice already and I’m gonna say it almost acts like it’s got more power
Bobcrappies that’s nice! Always need a little more power 👊🏼😎
