Big Problem

[Tyler09]

I have a 1986 yamaha 25ESH. I was changing out the water pump and forgot to put the shift rod in neutral so when i took the lower end off it was stuck in forward. Some guy who knew about boats tried to fix it but said that the shift rod was not in place in the gears. I would really apppreciate for someone to help me get the shift rod back in gear. thanks alot, Tyler

Re: Big Problem

if you pulled the shift cam up far enough to disengage it from the shift pin the only way to fix it is to pull the propshft and bearing carrier reinstall the shift shaft then the propshaft and bearing carrier, use new seals and orings as required.
normlly I shift them to reverse to remove the gear case,its easier.

Re: Big Problem

okay well i took the prop off and now im just looking at the prop shaft, how do i properly get into there

Re: Big Problem

with a service manual nd the correct tools.
mght be best if you take the gearcase to a Yamaha dealership.

Re: Big Problem

is it that much of a problem? i want to avoid a mechanic bc i wanted to do it myself. can the manual be seen online?

Re: Big Problem

it can be, especially if its ever been in salt or brackish water.
you can do some fairly expensive damage withot the proper tools,traing and service liturature but its your unit and your wallet.
dunno about the online manuals, I am a yamaha master tech so I have manuals and tools and 30 some odd years of training.
what is dirt simple to me is complex to others.

Re: Big Problem

Buy a manual and read up on it, If you think you can handle the project and want to buy the tools,then go after it. If not take to someone that has done it and has the tools with the knowledge. It is your money and the manual will help you for years to come if you keep the motor and work on it your self it will come in very handy.

Re: Big Problem

i did alot of searching and found the manual and theres no infotrmation that helps. It doesnt tell me how to remove the prop shaft.

Re: Big Problem

Was it a Yamaha repair manual? If so it should give the necessary steps and tools needed to do the job

Re: Big Problem

yeah it was, i just need to know how to get the prop shaft off. i see and on and off engravement inside by the shaft it self. All i need to know is how to get the shaft off.

Re: Big Problem

your not looking at a service manual,or you cant read.
in the yamaha service maual there are pictures and tool part numbers on how to remove,inspect and replace the prop shaft and bearing carrier.
you will need the claw nut tool,the carrier pulling tool and a set of dial calipers to properly measure the depth of the old seals BEFORE removing them to install the new seals to the correct depth.
most times I have to drill and break the claw nut due to corrosion,most times I also have to use oxygen acetylene due to corrosion.
certain tools you will have to buy,only place to get them s at a yamaha dealer.
most likly wil cost more than having the case repaired.
purchashing a factory yamaha shop manual and reading it first would have most likly prevented this thread.

Re: Big Problem

I'm always totally amazed by situations like this. Why do people tear into things without a service manual and skill to try and save a few bucks. Why not look through a service manual fist. Check what special tools are needed and be true to yourself about you skill level. Sometimes it's worth taking it in to a professional and have it done properly. I have to bring my own boat in and have the carbs set up because I don't own a manometer and I'm an Automotive Technician. I have no problem with people who want to learn and try it themself but get a service manual and be true to yourself about your skill level.

Sorry for the rant.

Re: Big Problem

I do 10 to 15 year,improper teqniuqe used,shift rod disengages an now they turn a 45 min operation into a several hour ordeal.
I am a marine tech,I was an electronics tech in the USN (FC).
before that I programmed and set up CNC lathes and mills,before that an auto tech.
I dont even check the oil in my 08 ranger,thas what the automotive techs do.
I have opened the hood 3 times since april of 08,all 3 times to refill the washer bottle.
nothing under there I have the tools or training to do.
I understand how the systems work,most are similar to the marine industry.
however none of my diagnostic software or scan tools fit anything in the automotive world.
the two most important tools a tech has.
1 the one on his neck.
2 the correct manual in front of tool 1.

Re: Big Problem

Take Rodbolts advice. You probably don't want to hear this but it is obvious from your line of questioning that you are not equipped to do this. Had you invested in the service manual to start with you likely would not be here with this problem. Check your local library. Some of them have a good selection of service manuals. E-bay is another source. Then there is always the dealer. And yes -- they are not cheap.

Re: Big Problem

that job,barring salt water corrosion, would take about 2 hours at my shop.
parts would typicaly be a claw nut,2 propshft seals,bearing carrier oring and a shift shaft seal.
probaly 210 230 dollars.

You do my lower unit when it's time and I'll tune up your Ranger!
