- IT'S THIS OLD OUTBOARD. 1983 EVINRUDE 25 Hp
DAY 2-3, TEAR DOWN. AFTER I GAVE UP THINKING MAYBE THE HEAD GASKET WAS BAD I KNEW THE COMPRESSION PROBLEM WAS INTERNAL . SO, TIME TO TEAR IT DOWN ! THIS THING LOOKS AMAZING !

T.O.O , You found me on a 6 year old I-boats thread, Dam I was feeling old already, Now I feel ANCIENT.. Thanks for the shout & love your channel. kodibass
Hey. Thanks! And yes, I thought that was kool when I saw your name on there, made me feel right at home. Hahaha Thanks again. Stay tuned !
I wish I had half your access to old outboards.ilove checking out anew to me outboard like Christmas every day. Joey bunker saline Louisiana
Thanks again & Stay tuned !
Love your videos the only thing on TV. I think you like outboards as much if not more than me if that's possible. Joey bunker saline Louisiana great videos
Hey. Thanks I appreciate it. Yes caught the outboard fever! Hahaha Thanks again & Stay tuned !
I've got this same motor over here in New Smyrna Beach Oak Hill area. Just rebuilt the whole damn thing. Having a tough time keeping it running. I"ll keep watching
Hey. whats it doing
I love your videos can't turn the dam things. Off. Joey bunker saline Louisiana
Thanks for tuning in!
Dude your awesome, stuff you do is stuff I would do, Like working on the water..lol...Where in Florida are you? I have a problem with my 1992 40 Evinrude...
Hey. Thanks. I'm in o-town. Whats it not doing ? Thx again . Stay tuned !
I love the Plano "tool box"...! As for the stuck ring... that's why you run 1 oz of Seafoam / gallon of your premix fuel...! (It would have prevented the carbon buildup in that ring land.)
Hey. Thanks 👍 . Stay tuned !
I wrap the rope around the FLYWHEEL twice, then around the leg of the engine stand, it works fantastic.. no fighting what's so ever
Wow Sounds good ! Thanks for watching and commenting. Really appreciate it. Stay tuned !
Glad you were able to figure it how.. So how do you get all these engines and wear do you find them at?
craigslist !
@@THISOLDOUTBOARD1 have you ever came across motors you can't fix?
Hey. Not really, everything is pretty much fixable , it really depends on how much time/money your willing to spend on it. I like to stay under 2-250. Like this motor, the guy was asking 125, which pretty much means 100, which is what I paid, but I probably could have got it for 75/80. Overall, the parts, (which is what it was advertised as, a ''parts motor'') the electric starter and bracket, carb, etc is easily worth more, but I'm not really into selling parts although there is money to be made in parts. The whole idea is to have a good running outboard at a fraction of the price. Down here a 25 horse short shaft tiller in good running/looking condition can bring 7-800 + easily. Anyway back to your question, everything is buildable, it just depends on the builder and which direction they want to go (hint hint). I'm at 100, and 1-150 left in my budget, 100 would be better, Hahaha. So, can I get it up and running and stay within budget? Stay tuned and see which direction I go! You never know whats gonna happen next with ''This Old Outboard'' ! Thanks again for watching and commenting, I really do appreciate it. Stay tuned !
I just got a 1979 Evinrude 25 HP Model 25904R,,I found a broken piece of Plastic ( odd shape ) I pretty sure you will know what it's for and where it needs to be,,I just can't figured it out,,don't know how to show it to you, unless I message it to you,,hope you can help, thanks and I love all your videos.
External timing advance cam... (Very common failure on Johnson and Evinrudes)
Thanks for tuning in! Just catching up!
That's how it's done baby good job that's good mechanic work bunk auto n small eng
Hey. Thanks again for watching !
I've got a johnson 25r72r. How do the rings face when being installed on the piston and how do I tell the top ring from the bottom ring?
Hey. Thanks for tuning in. Look at the piston ring grooves, you'll see that the top groove is beveled to fit the top ring, it only goes on one way. Thanks again & Stay tuned !
@@THISOLDOUTBOARD1 appreciate the input and your content
What should the compression on a johnson 25r72 run after a fresh rebuild?
@@Southern_Illinois_Outdoorsman well there is no "should be" numbers but I would hope it would be 120+ on both cylinders
I need some help other than what does video shows I've got a 78 25 horse with a hole in the housing and I'm not sure if it's an exhaust hole or if water would get into the gear casing. there's nothing else wrong with the lower gear casing housing except there was a peephole that started eating itself out around the hole and somebody while or somebody cut a bigger all-out I guess they were going to put a plate in there aluminum welding
Hey. I think I understand what your talking about. There is a drain hole that allows the water to drain out of the cavity located in the upper part of the gearcase behind the water pump so it dosent stay full when the boat/motor comes out of the water. Its located next to the shift shaft bushing/seal in the top of the gear case and drains down lower out the side weep/peep hole. It has nothing to do with exhaust. I've had a few that were clogged and gently drilled them out. You should be all right unless its eating into the gearcase and letting water in. Check the oil. You could plug it up with bondo or jb weld and try and dump the water out of the cavity when its out of the water. Water sitting in that cavity will only cause more corrosion.
@@THISOLDOUTBOARD1 THANK YOU FOR THE HELP, VERY USEFUL INFO
I have this same motor. My shifter won't go into reverse unless I get a "running" start from forward and slam in back through neutral and into reverse. Does that bolt outside on the lever adjust for that?
Hey. I would think it does or should, but it dosent, or I'm not doing something right. You can take that small panel off, with the two screws on the side of the mid/exhaust section and check your shift linkage, the brass connector may be worn or loose. All it takes is a fraction of an inch in the linkage to throw the whole thing off. You'll see what I mean in my next vid coming up in a day or two.
When I lift up the bottom of that black vertical pole with the two springs on it I can shift it easily. I wonder if someone put the wrong springs in there. They make it so hard for the lever follower to move backward.
@@thull1234 yeah I noticed that to, the top spring is pretty strong . you could try and cut it to relieve some tension . ?
@@THISOLDOUTBOARD1 I finally had time to take that spring assembly apart and cut the spring. Took off about 3/16". It worked! Now I can shift into reverse, neutral and forward fairly easy! Thanks for the help.
Cool man glad it worked for you. Good to hear back from you. Thanks
We got to get you the real OMC flywheel puller and one of the electric impact guns from HF (only $40)! These things make removing the flywheel nut and popping that flywheel a breeze...I forgot to look, but did it look like the crankcase has been split before (paint off bolts/sealer oozing out between block halves)? It is impossible fore me to judge from here....Those two rings are different design, different end gaps are normal. The top ring is a "pressure back" ring, it uses the combustion pressure to help expand it....You might want to measure those piston skirts and cylinder walls prior to reassembly, who knows what you have there....I didn't see anything that would explain that compression difference...OK, you found that the bottom piston is oversize by .030", an OEM piston was used. Is the top piston standard or oversize? Again, I would advise measuring those piston skirts and cylinder walls before reassembly...Check new ring end gaps and ring groove clearances as well....I sure don't want you to put this thing back together only to have the same issue.....
Hey, yes I plan on checking it all out before I even buy anything , the top cylinder was not bored out, will that make a difference ? Thanks again
It is perfectly fine on the OMCs of that era to have one oversize and one standard cylinder/piston, it won't be "out of balance"....Hope it works out OK....
Ok, thanks .
hummm very interesting
hey. this thing has some nice parts in/on it. Its a damn shame! thanks for watching/commenting. Stay tuned !
AND THEN SALE IT AS A TOTALLY REBUILT OUTBOARD
👍
Smoking danger. Big bang ....kkkkkkk i brasilian .
Hahaha. Thanks again !
Wow hopefully they bored both cylinders.
Hey. no they only did the bottom, do you think it will make a big difference, I was told by a mechanic that it probably wouldn't be noticeably .. ?? thanks for watching and commenting . Stay tuned !
