Thanks for this video. I've got the same outboard, 1970 model, that hasn't run for over 20 years, but is in excellent condition. Got it running without tearing it down, but it was stalling after 30 seconds (not drawing any water thru impeller, though). Pulled the carb off and ran cleaner thru it even though it looked very clean. Now it won't fire. *SIGH*. Oh well. Thanks to you I know what to check and how to fix it.
I just got a 1973 Evinrude outboard 25hp that had sat for 2/1/2 years, and like you too I had to remove mice nestd. Now I'm in the process trying to get it restored.
Lol, i have a 65 crestliner super seaman with a 70 20hp seahorse, boats about worn out, love the seahorse, new upper crank seal & ignition oarts its like a old chevy, always runs.
Excellent job of explaining your process. Thanks very much! I'll be restoring a '70 Evinrude Ski-Twin soon - and will rely on your site. All the best, Steven Jay Sanford
Sound and looked good. I have an old 63 I think 9.9 seahorse that I need to get going again. Need some lower unit parts but use to run great!! Used in the rivers here at home fishing and duck hunting!
Thank you for all the info I am Working on a 1971 20 horsepower s The saltwater version but it's electric start Cannot find a wiring harness so we can have a turn key I am going to try and fabricate one myself Anyone have a suggestion on finding a wiring harness for a 1971 20 HP Johnson
Fixed one of these for a family friend good old outboard when rude and Johnson's made quality easy to work on engines idk what happened after the 90s 🤢 just got gifted an 89 35 merc that had a rat nest in it what a shame engine barely used but the guy had the drive shaft rusted to crankshaft and he cut it in a way that i have to replace both plus fix all the chewed up wires uts really to much work to be worth while unfortunately guess ill part it out or junk it for aluminum cool vid bud going to do this for my Buddy's 69 20 and try to make something to flush with out a bucket seems something like a rubber nozzle with hose attachment
@@Michaelsbackyardmarina that's cool I was hoping my Comment would help athers on your channel. Thanks for your respon to my comment i hope you have a great Father's Day.
Actually I do need parts for the old 20hp. I'm pretty sure the gear box is going out on it. More you tube content. Send me some pictures. Let me know what you want for your parts.
Great video I got the same motor it’ll start and run and piss but once it gets hot it shuts off and won’t start until cool again any chance you know the problem
Just watched your vid on this Engine. I have a 70 20hp outboard. I am doing some repairs on the lower. I wanted to buy 2 sheer pins/prop pins and followed the link and its sold out. When will it be restocked? Thanks, Chris
i have the same motor i just recently picked up but the bottom spark plug is working and the top is not any idea? im gonna pick up a flywheel puller to check it out, but i seen that the bottom plug has wire in it and the top has this nylon in the middle. i was gonna take a little peace off and put the boot back on but still nothing. any idea???
I have a 25rl69b. I’ve watched all your videos on your 20hp and did everything but put the pee hole in mine. It’s running great, but I can’t get full rpm in the water when in forward. Neutral and reverse I can get full rpm. Any suggestions on what I should look at? Other than gas line (already checked), compression (at 100 in both). Have spark. What else is there?
Thanks for the help on my 1970 20hp Johnson 20R-70E motor. I ordered parts and cleaned the carb w/ kit, replaced the fuel line, fuel filter, and impeller. It finally runs. But it runs on the rich side. Q: on the lower unit it gets kinda hot. Is it suppose to shot water out the back pee spout/hole? It doesn't. Could it be plugged? I was told I might need a new thermostat? Thanks again,
@@Michaelsbackyardmarina Opened up the area where the thermostat is suppose to be. No thermostat. So ordering 1 with gasket and ring with Crowley Marine. Did a test and water was running back out through the intake and wouldn't flow through other chamber - no peeing from rhe lower. Thanks again.. Q: do you have any suggestion on fixing a motor cover to the outboard? The latch connector on my motor (anchor block and pin) is broken.
I have to tell you Mike, I took out the Merc Mark 10 for a lake test and started then died. I got tired pulling the cord and gave up. After thinking about it I realized this motor must have a vented gas tank. The auxiliary tank I was using just has a cap without one. Woops on me. My Yamaha kicker runs good with that tank but this old motor won't have it.
Seems like I haven't seen very many videos, lately. I've been subscribed since before you started your second channel. Maybe UA-cam hasn't been letting me see your channel....or maybe you weren't very active? I'm glad to see this one and settle in with my morning coffee to see your mechanical adventures.
@@Michaelsbackyardmarina thought it might have been Covid 19 related...either way, I was glad to see your work. Especially, you providing an amount you paid for that one. It gives me an idea of what I should pay for one, if I were looking to do some refurbished flips.
Love your videos Mike! I picked up this exact same motor at an auction and have done all the same TLC that both of your videos show. I have a somewhat dumb question. On the lower housing near the bottom pivot point there are two holes that face the transom. When the motor is running I am getting water coming out of these as well as exhaust port and pee hole. Is this normal? Seems like the whole lower housing fills with water? Replaced lower shift shaft seal and am not leaking water into gear case. By the way, my brass bushing detent pin sticks up a little higher than the 3 you showed. Did not have to install a second tension pin.
I’ve got to get some of that see thru line. My 92 Johnson 28 hp has a cold start problem, have to excessively prime to get started maybe it’s the line?
@@Michaelsbackyardmarina Is the fuel line 5/16? I have a 71 Johnson 20hp that my dad bought new. I have to pump the primer bulb to keep it running too. Also is the timing/linkage sync right between the lines on these old Johnsons?
Hello there, I'm having the same fuel pump issue with a new complete part. It ran once just fine on the water for several hours. The next outing three weeks later I had to pump the fuel bulb to keep it going. Did you figure out the issue with your faulty pump? Mine is tight and everything else is squared away as far as I know. Thanks so much for your videos!
Some of the cheap Amazon pumps aren't as good as some OEM ones. Make double sure you are sealed up on the back side and that your screws are not bottoming out. Thanks for watching
@@Michaelsbackyardmarina Looking forward to the Sea Nymph meets the Johnson Video! Will that 1/4" ID line work on my '98 20HP Evinrude? Its calling for a 5/32" ID line. Sorry about the newb questions, but I have learned a tremendous amount from watching your videos!
Awesome video, I love how the same reliable carbs are used throughout the years of these motors. I really like your water tank setup with the exhaust vent, do you have a video on how you set that up?
Help. Great vid. Q: I need a water pump kit for a 1970, 20hp Johnson outboard. Model# 20R-70E serial# J3242862 Can't find one online. Checked several marine stores, Ebay & Amazon. Also need a carburetor kit. I will be buying several of your prop kits in the future. Thanks
Do you have an email I could email you at with some questions? I just bought a 1967 20hp and it came with a 1963 18hp what he called parts motor for free.
Hi I just got a 1981 starcraft v6 its starts right up but I never owned a boat and not sure what it should sound like no smoke revs up good and tips on anything I should listen for thanks
Why don’t you test the lower unit ? In my routine that’s one of the first things I do ! Shift rod seals and drive shaft seals are easy ! I do like those 20hp and 25hp of that era ! I have 2 - 20’s and 3 - 25’s pre- low tension and I sell a butt load of them and 15hp outboards !
Sean, you are a little a head of me. The next video on this outboard will be EPIC and you will see how the Banana treated the Nymph and how the Nymph handled the Johnson. Drift received.
Hello, my name is John. I can't find anything online about this, so I am going to hope you may be able to help me out.. I have the same model 1969 20r69d engine. From the manifold to the fuel pump plate there is a small hose that connects them. Mine was dry and it broke so I replaced it with a clear piece of tube. Anyways when it's running I see slightly yellowish kind of Milky fluid running through it and I'm not sure if it is water in the gas or if it is dirty water or what, perhaps you can explain to me what this line does and what is supposed to run through it? I can find nothing on the internet about it and I do not want to blow up this bad boy!

Thank you for making these videos because I never had an outboard motor before, and now I'm trying to learn to get it fixed and running.
I'm not a boat guy but this video is very informative and well done. I've been recruited to help get an old 20hp Johnson running again.
you can do it, plenty of video help out there.

Great 20's from O.M.C. My son runs a 1970 20 hp. It outperforms his working buddies 25 hp 4 cycle Mercs hand down with extra go to spare.
They are nice old motors for sure, thanks for watching and commenting
Always a great learning experience watching these. I have a 1959 Johnson 50 hp I got for 100$ I haven’t started on yet….
That will be a fun old motor to get running

Any recommendations?
Yes, what hp? over 10 hp then buy it and watch videos and fix it up.
