This video was what I was looking for as far as changing a head gasket. Not sure yet if I need to on my 30hp Evinrude tiller. But if I do, I feel confident I can do it with your video. Thanks for sharing the sand paper trick too. That was very interesting and helpful. I have watched a few of your videos and always find them useful. Enough that when I search UA-cam for video for my boat, I keep an eye out for the Hawaiian shirt when scrolling thru the list. LOL! Thanks again.
The sandpaper your looking for in 180 grit is for an inline sander. 3"×16" sticky back. I stick several pieces to a piece of glass and do figure 8s. Automotive painter for 34 years/outboard hobbyist. Great channel,enjoy the videos. Thanks
My Johnson 20 seahorse i bought might have this issue too. I bought it recently and didnt do the proper checks. Just pulled out my wallet. The impeller was stripped and i believe it over heated. My compressions are currently 95 top and 60 bottom. I hope your video is my solution too. Excited to work on it.
Good video! Learned a lot 👍😬 . Lucky haven’t got one with a over heat problem yet, been collecting outboards ! You , kodi , and this old are my favs. Look every day for new vids 😀keep um coming. Can’t get enough!!!!👍
Great video Mike. Just picked up a 82’ evinrude 25hp. Bottom cylinder 110, top 70 psi. I’ll do this sanding procedure, if the crankshaft seal checks out. P.s…parts in the U.S are a lot cheaper and accessible than here in canada 😖
Thanks for the update on the 20 hp mercury I hope the drive shat doesn’t break on you when your testing on the Good Enough boat. Great work on the fifty horse motor and with all the resistance gone on the throttle cable it looks like you got a good fix there and things will flow smoothly. Looking forward to the carb work. Thanks, Tim
Hi Mike, I started using my Dewalt drill motor 1/2" to work with my motors but it was too much for a cordless. I bought a 1/2" corded Dewalt on sale for 90 bucks at Home Depot and works great. I also bought a ratcheting 1/2" adapter that is reversable to start the motors to save the old arm. With the adapter when the motor starts the adapter will free spin so it doesn't take you and the cord for ride.
Awesome man! I did the sanding on my old 25hp johnson with the figure 8 but really didn't know if I was doing it right. Thanks for all the explanation. Whenever I go back to fixing her up I'll know what to look for right.
@@Michaelsbackyardmarina do you have any vids of rebuilding a recoil on a 87 20hp johnson.ours needs to be cleaned and the rope broke and a spring also a plastic dog broke.PLEASE HELP.any parts brake downs.to look at
water pump ? looks like you will have a nice runner. i just picked up a 1958 3 hp johnson and that makes number 8 for me, yes i have a problem LOL, keep up the great work and have fun.
Just picked up a 96 evinrude 25 hp. Great compression 128 in each cylinder. Runs like a dream. But today looking it over, I noticed a drip of water on the bottom of the cylinder cover, give it some gas it would sputter water there to. So I’m guessing just go ahead and do a head gasket and cover replacement.
What you are calling a head cover is what’s dripping some, and with a little throttle it will spew, bubble at the bottom side. Maybe bc when throttling up the impeller is forcing the water faster causing it to sputter even more water out the bottom.
If the water pump was in good shape , check the grommet at the exhaust housing gasket.. I'm doing this on my 9.9, it was peeing good but overheating at high rpm and loosing rpm about 10 min into a run
Nice job! Got a 1980 50HP Johnson with 90 PSI on both cylinders that runs and pumps water great for about $500! I total agree with your comments! I will be replacing the wiring harness before putting it on the water! (wires are a bit frayed) But to your point, if you have compression, great spark from the CDI/coils and the fuel is coming good from the carbs, you are in great shape! Thank for the video!
i wouldnt worry about the bolts. my guess the paint will change color around 550 degree and the bolts get annealed after heat treat far above that. i start with 80 grit anything over .006 go just till i see a scratch on the low spot then 320. table saw table is good to .001 i checked it. i'd really look close at the water pump and everything connected just because how that thermostat looked. it was run dry.
I will definitely use courser grit to start. Had to go with what I could get at the moment. I have replaced the water pump but I will check for blockage before I put the gearbox back on. Thanks for watching
Great video Michael ! Always pick up a few tips from your videos. Thanks ! I've got a 1958 35 hp Buccaneer that was seized from sitting for decades. I got it freed up & running, but it won't idle (I've disassembled & cleaned the carb) & it also coughs or misfires quite a bit. Some times it'll smooth out & run like it should. I've only run it in a barrel so far. Compression is 105 lbs on both cylinders. I replaced one coil, cleaned the points & it has good spark on both cylinders. I slso installed a Kohler fuel pump, as I'm sure the original wasn't pumping & an NOS one is outrageously overpriced (not to mention having sat on a shelf for 60+ years, it's probably no good). Any thoughts or suggestions ?
parts for some are just not reasonably price anymore and that's break my heart for sure. I still want to bring them around to running anyway. thanks for watching
Thanks Mike for the informative video. We have an 82 Johnson 35 hp. It would be appreciated if you could tell us where you find your parts as we are having a hard time finding parts we need. We are living in Canada and have to order from the States.
Another great instructional video. That cylinder head turned out great. Good job! Question…How do you keep your shirts so nice and clean? LOL. 😀 Thanks for sharing.
hello from Norway here. i was wondering what the torqe specs are on the top end? I have an 84 mod, with 50 psi on both. I like this videos alot! Thanks!!
Hey I have a question... Just finished fine tunning my 1971 Evinrude 15 had it running for an HR and I noticed oiley foam gray color inside exhaust is this normal?
I am looking at motors for A small aluminum boat. I can buy one from a friend that has a 1980s 20 Johnson. 750.00 tiller or I found one on Marketplace that is almost brand new Mercury 6 hp, 750.00 I have had many people tell me to get the Johnson that it is a way way better motor even though it’s very old and the company is no longer. Other people are saying get the almost brand new Mercury . I know they are not apples to apples but I am trying to get a boat that it the right move for money and reliability. Can you give me some advice ?
If you need a flat sanding surface put a straight edge on your pizza stone mine is flat and work's good. If you need to make one if you have some leftover epoxy you can pour one. Enjoyed the video.
With it getting that hot I would wonder if the head cracked or warped I'd say the same thing about the head bolt's I would not trust them so I would not use them bolt's
hard to say what might be going on with that motor. I will get it to pop and run and make some more decisions as to what to do with it next. Thanks for watching
Find me on Facebook if you like. I have a couple older motors that I’m sure you would be interested in you have bought one or two older motors from me in the past.

I do the same stickyback paper to glass...I too was a car painter back in the day...
Just fixed my 77 Johnson 35hp by following this video. Thanks a bunch. Also replaced thermostat while i was in there too
Awesome, thanks for watching and comments
Great video, really helpful using what ive learned for my own 1979 35 johnson seahorse
Awesome, glad it was helpful, thanks for watching

Good video! No gasket sealer? No antiseize on the bolts? I know..those head bolts are pricey!! Thanks for the demonstration!
I’m wondering the same thing about gasket sealer. Not at home right now so I can’t check my service manual to see if it says to use any or not

Thanks 👍 I will keep em' coming for sure.
Good job! Fairly new to the channel and I've learned a bunch thanks. Like the Johnson's little runners!
Glad you like them! Thanks for joining up and watching
You are great at this!!!! When will part 3 come out???? Pleads hurry!!

water pump ? looks like you will have a nice runner. i just picked up a 1958 3 hp johnson and that makes number 8 for me, yes i have a problem LOL, keep up the great work and have fun.
They are addicting. Thanks for the long time viewership.
Great video again Mike . You need to get yourself a nice little glass bead cabinet would make those parts look like new again
Great idea
@@Michaelsbackyardmarina where can I find a brake down of parts for a 20 hp Johnson motor.i have model and serial.thanks.
Mike I would also check the exhaust port cover plate.
I think I will replace those gasket after I hear it pop and run for a little bit. Thanks for watching

That head turned out nice after a little elbow grease. Not sure what a ruler is, definitely nice to have a good scale for a straight edge!
LOL, thanks for watching

Awesome video. Just curious what’s the Lowest compression that you would consider “decent compression”
Thanks Mike for the informative video. We have an 82 Johnson 35 hp. It would be appreciated if you could tell us where you find your parts as we are having a hard time finding parts we need. We are living in Canada and have to order from the States.

hello from Norway here. i was wondering what the torqe specs are on the top end? I have an 84 mod, with 50 psi on both. I like this videos alot! Thanks!!
Work center out. 10 ft lbs the 20 ft lbs. I believe I spoke about it in the video. Thanks for watching
Why did it over heat that caused all of that? Water pump or thermostat or both?
Really wanting to buy an older tiller handle an rebuild. What would you consider as the most reliable an easy to find parts for these days??
I have a 1977 35 hp johnson it's not peeing out the peehole it's got water coming out the 2 little exhaust ports what could it be
try blasting some air up through the pee hole. Little varmints like to make little cocoons and block the hole.
Did u do a part 2 on this outboard?
Still in the works, I got compression, the rest should be easy for sure. Thanks for watching
Michael could the fuel had leaked out when running and started a fire when running and was not caught then caused damage Chris
The hood would show signs of that if that is what happened. It's just a plain old overheat situation, thanks for watching
Hi from Richard can you give advice I have 2.6meter 8ft fibreglass dinghy what size HP outboard do you recommend this is first boat
I would not go bigger than a 9.9hp for sure. thanks for watching
@@Michaelsbackyardmarina thanks I'll get one I'm learning to an can fix mine when I pick it up I'm in new Zealand

I'm definitely going to see what it takes to convert it. thanks for watching

I only have one for sale right now and it's a 1969 Johnson 20hp. Thanks for watching
@@Michaelsbackyardmarina you have any info on it? I need something that runs. Don't have time to fix the one I have.

If you need a flat sanding surface put a straight edge on your pizza stone mine is flat and work's good. If you need to make one if you have some leftover epoxy you can pour one. Enjoyed the video.
