Thanks a mill, Brandon! It was all about that goofy shift rod bolt that needs to come all the way out! The rest should be a piece of cake! Kudos to you!!!
Excellent video, crisp and to the point. Looks like it's not strictly necessary to remove the prop if doing a straight lower unit swap, as I intend to do from an Evinrude with seizing issues to another of the previous model year that had a shot lower unit that had been removed.
Am currently wrestling with the bolt - not moving. Have tried fluid, heat, leverage, nut on bolt and whacking a length of flat metal onto the nut. No joy yet ... Thanks for the video. It is good to see the path ahead. Pity about the choice of materials and the electrolysis / corrosion. Great to see the exact same motor from the past. Hoping to get father in law's "tinny" back on the water before he falls off the perch. GF Wollongong
I wrestled with the same problem. The bolt and the hole had almost corroded to a solid unit... However I solved it by stacking nail plates on top of the bolt, and then unscrewing the nut against the plates to push downwards on the bolt. Any pieces of flat iron will probably do but make sure you fit as much material between the bolt and the roof of the hole/shelf where the bolt is, to have more thread. The upper threads might take some damage, but they can be remade easier than the whole lower part if you were to damage it while trying to knock it loose with a hammer. Some extra lube on the bolt and nut might also counteract the deterioration. Hope this helps.
I wrestled with the bolt/stud like many others in the comments.

I'm helping a friend with his new Project , he has the same Outboard,,but from 1979 Evinrude Model 25904R, 25 HP. We got it running, so decided to do all the basic Tune-ups.
I just bought what I believe to be a 25 horse 1985 johnson. I manually lift the motor up when pulling into shore. However the motor doesn't stay in the up position. Is it suppose to? How do I keep the motor locked in the up position when either taking it out of the water or trailering it?
The one I am working on has a bolt instead of a stud and nut, it’s the one you sprayed. I think it is a 1963 18, anyway I think they installed a nut that was large enough in diameter to thread into the midsection and lower unit. It broke off with out coming out any and it is about a 1/4” recessed into the hole. Uuuggghhhh
after following your steps the motor seems to be highly revved, and it is not the speed throttle, and ideas what can be the issues please? also is it normal that the water pump is too tight that the blades bend when inserted?
I just bought the same motor with the lower unit in pieces. Can you tell me what orientation the water tube installs? Straight section be on the motor end with the bends on at the pump?
Great video! Does anyone know where to get a new prop like this? I have the exact same model but can't seem to find a new one. Some help would be greatly appreciated!
I have a 1978 25 horse shipmaster, very similar to this ingine, but have a hard time finding parts, what water pump, "part number" am I looking for, because I can't find one that matches mine. I can't find most anything that matches my ingine. Or were can I look to find parts for my ingine?
Great videos. I need to replace the gasket on the lower portion of the split lower unit on a 1979 25hp Johnson. It's leaking some gear lube. Can I do this without taking apart the entire lower unit? Can I just remove the portion attached to the skeg?
I recently purchased the same motor, it needs a impeller and I cannot remove the lower end I did everything you did but that one nut/bolt is siezed badly from neglect and I cannot get it off... any tips? Should I just cut it off? There are 4 other bolts holding it on how detrimental would losing that bolt be?
Hi Brandon. Great video because I have the same motor on an old jonboat I just got and I need to replace the impeller. Question is what does removing the lower bolt do (of the 2 behind the small plate with a gasket) that you took from the rod that continues up into the motor? Do I still have to remove the shift linkage at the motor end of it? OR does removing the lower bolt allow the linkage to detach at that point instead of having to remove it from the top? Thanks for your help.
I have this same exact motor and have taken it apart 3 times with the shaft being stuck in the powerhead every time, do you have any idea what could be causing that?
Worn splines, on the crank or the shaft. Ever had a slightly rounded nut get stuck into a socket? Same concept. Or you're not putting grease/molly lube on the splines when you reinstall; and rust/corrosion is getting to it.
I have the same outboard, I have removed all the bolts including the one for the shifter. and the problem is that I can't get it off and i have no clue what i should do. do you have any tips whitch could help me?

Don’t get why someone would thumbs down a free tutorial
Seems 5 people wouldn't agree with you.

Did you get it off ? I'm having the same issue.

Thanks for the helpful video just took one like this apart and the impeller was shredded!
Thanks! Mine is stuck on there the stud going up is corroded in place. Spraying with pb blaster

You're a life saver

Great videos. I need to replace the gasket on the lower portion of the split lower unit on a 1979 25hp Johnson. It's leaking some gear lube. Can I do this without taking apart the entire lower unit? Can I just remove the portion attached to the skeg?
Probably. Well, yes you can. But doing it with the engine upright will be hard, esp. if the gears come loose.
This helped me alot thanks for the awesome video💯

Your a legend thank you sir 💯

is this a commercial model? i have a commercial model it looks the same. Can i swap a non commercial lower unit on my outboard?
I think mine is too
what is the hole to the left of the foot oil fill plug. why would oil be coming out of it?
I have this same exact motor and have taken it apart 3 times with the shaft being stuck in the powerhead every time, do you have any idea what could be causing that?

new subscriber, great videos. lots of great info, thank you.
I found this website that lists all the outboard tools and what motors they're for...everythingoutboards.com
Why did you take the prop off
do i have to have dent spring in a 1975 25 HP evinrude
helo sir,i have 25 hp evinrude and i dont know where the water cooling inlet.can you make a video about it.thank
I have the same outboard, I have removed all the bolts including the one for the shifter. and the problem is that I can't get it off and i have no clue what i should do. do you have any tips whitch could help me?
cant get the shifter off? Does it move okay, or is it like mine?
Why is oil coming out of the access port to the shift rod on my motor?
Cause you got a bad seal under your water pump probably
I wish the bolts came off that easy i had to beat the crap out of them and use heat
which year this engine?
Back bolt is odly different than the other 3 on mine as well, must be factory
Qual ano esse motor
Blue gloves wants up with that lol
