Yamaha Outboard Shift Shaft Seal And Water Impeller Replacement-Step-by-Step! 

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.

Thanks for stopping by man I did a lot of research and nobody really had videos on it so I thought I do one

Thanks

They quoted me $105 an hour thanks for stopping by we’ll see you soon

Thanks I really appreciate it!

Great idea

Had it out in the water twice already I think it even runs better with more power

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!

I’m not sure but it’s got to be about the same set up and thank you for stopping by

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

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 !

I wouldn’t charge you I would just help you

@@bobcrappies I like that idea!

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

I’m not sure I understand your question as the speedometer cable was inside on this outboard

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....

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

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 👊🏼😎
