Johnson 15 HP Rebuild; Part 1, Teardown

[@waynemiller4911]

This video is the only reason I even considered doing a full rebuild. Can't buy these old light 2 strokes anymore, so I feel it's worth a few bucks and a few hours to fix. Thanks a million for making and posting this

[@jimijones9725]

Great job Brandon! In my opinion this is one of the best instructional outboard teardown/rebuild videos on KZbin. I own both Johnson and mercury outboards and have watched a lot of related videos here and this is the most complete and easiest to understand and follow along with that I have seen so far.

I like your videos are very educational thanks for the time spent on all your videos to educate some of us

[@andyhadsock3287]

Just wanted to give you a shout-out, I followed your videos on the Johnson rebuild, I just took my 2000 15hp tiller through a total rebuild, couldn't have asked for better hints tips and some how to's on the process, as of 1/1/21 the motor is back on the boat and going through the break in steps, can't thank you enough for the information

[@samtate1260]

I started watching this series at the second one just now got to the first thanks again for another great information video 👍

[@realmikeq]

Really great video series, very helpful. One the better instructional videos on here. Thank you.

Hi Brandon. Your videos are very helpful for me working on a complete rebuild of an Evinrude Fastwin 18HP year 1960. Here's a question. There are two guide centering pins which are tapered. They are used to center the crankcase cover on the cylinder block. On disassembly one pin remained in it's hole in the block, and the other pin remained in it's hole in the cover. I have bought new pins, but I don't feel confident punching them out due to possible damaging the cover and the block. What do you think I should do?

[@gioscervelo]

At exactly 5 19 when you hold up the reed plate. You can see on the plate by your thumb a channel from one side to the other. It is about 1/8 inch wide and 5 inches long. What is that for. What does it do?

[@nealmaraia9604]

Great Video. Any advice on how to seperate the powerhead from the exhaust housing 2006 J15. Have the 6 screws removed but it wont budge.

[@brandoneid8028]

Any idea if it's possible to replace the reeds without removing the power head?

[@RooftopwarriorPsalm91.4]

I have a 79 15 hp Johnson seahorse. It idles but if I give it any gas it chokes out. Cannot figure out. Carb rebuilt twice. Any ideas

[@richardbarnett7058]

I have a 82 115 Johnson the impeller were out on it and it got very hot I changed the impeller and compression is good on all cylinders. Now the motor runs but takes 15 to 20 minutes before it will open up and playing before that it is only about half throttle. Any suggestions

[@mbearden84]

Love you channel. I have a 1975 Johnson 15 hp and the engine cover seal is pretty much gone. Do you know where I could get a new one or something aftermarket to use?

[@chadbosko8935]

Hey brandon i rebuilt my 9.9 evinrude and i just can,t get it to shift right now do u have a link to a video on putting this back together please, trying to adjust this throttle to work so that it shifts properly

[@tommyjackson6216]

Lost my water pump on my 9.9 put new pump in now it want start just back fires did i destroy my engine ??

[@welshfooey]

Hiya Brandon watching these vids inspired me to my 1979 15hp thank you for the in depth and very clear detail and instructions and advise, now I've a question it's been bothering be as it keeps rising it face, I keep hearing that Johnson evinrude actually struggled to get 15hp out these motors untill early 80's where a series of updates or upgrades were added, 1979 they added the tuned exhaust then 81-82 the Reed plate had adjustments made to make it a true 15hp so anything before a little low on power , can you shed some light on this if its true or not I've an opportunity to pic up a 1986 15hp which I was gonna use for parts that that reason Cheers Kris

[@silverhorseman3541]

hi have a 1978 15 hp Evinrude. have a problem with the steering column. The upper mount seems to be sliding lots and I can rock the power head and steering column within the exhaust housing. it makes a click noise when fully pushed back then pulled forward. but vibrates with a rattling noise. is there a video on how to repair that? unsure if it is bolted down or how to get at that part or what parts are need for that fix. thanks for you help good videos.

[@BrandonsGarage]

I dont, but this video might help: kzbin.info/www/bejne/fnSraJpsprCJfqM

[@silverhorseman3541]

thanks much appreciated

[@AaronGoSoFast]

Awesome video. That hammer work at 3 minutes though. Pretty funny.

[@BrandonsGarage]

It sounded like a wood-pecker! At least it was a hammer. Usually I just use a wrench or something.

[@reelistixoutdoors4077]

Do you have videos of 4 stroke evinrudes?

[@HornetGaz1976]

Does anyone know if 1975 15hp evinrude and Johnson parts/gaskets etc are all interchangeable? I have an evinrude 15hp to rebuild and would be help to know if all parts are interchangeable for ordering new parts etc. Thanks

[@BrandonsGarage]

johnson / evinrude are the same engine. Evinrude just has fancier colors.

[@robertpc100]

grind off an old socket for that bolt close to case,taper the end,works good for alot.whatever it takes

[@brianwinterberg9699]

I just opened up a 1982 Johnson 15hp, the top piston is pitted as well as the head. I can find neither available now. Any hope to replace or repair?

[@MarcDechico]

I don't know if I can ask such question here but I have seen that you have used a simple rubber tube to replace the grommet (Upper water tube 330426). Do you know where I could find the tube or indicate it's size?

[@prevost8686]

Dad ran one of those for a long time. He was a Johnson fan til he died.

[@fleetwin1]

I'm joining this thread late, but am wondering why you are tearing this powerhead down, everything looked OK inside...It is easier to drive that crankcase taper/alignment pin out before removing the crankcase bolts. It is driven out from the cylinder side toward the carburetor side of the crankcase.

[@BrandonsGarage]

Just to give it new rings, gaskets, paint, seals, and to clean it up.

[@BlackoutBilll21]

Brandon, when you mark the pistons, are you marking them because the pistons have to go back in the same cylinder? what if you order a new piston? or is that just to keep the rod cap with its respective rod?

[@wish2fish37]

I enjoy the tear down videos.Nice to see what these are made of.I have question about carbon build up on pistons.My 20hp Johnson has carbon built up on the lower part of piston, but up on the flat area it almost looks like rust on both of them.Yours have carbon and black on the tops of both.Any idea about this?

[@mrsuarez430]

For the life of me cant get a 15 carb to run right on my 9.9 Ive cleaned it put in two kits put a new pump changed fuk lines but fuel doesn't get to plugs dpubt its the reeds as i cleaned them last year im thinking a blockage at the lead plugs on the carb its nuts blue spark on the plugs so not a power prob fml i want to go fishing but Got stranded last week

[@Robert-rr4rk]

Awesome video. I have a 9.9 with a dry #2 cylinder any idea what would cause that?

[@BrandonsGarage]

Reeds/leafs probably.

[@Robert-rr4rk]

Can I remove the intake without pulling the whole power head

[@ReN-bg4xp]

Brandon, NICE VIDEO! I have a 1980, 15 hp Evinrude which looks kind of like the Johnson. It has low compression of around 60psi but still runs. My marine shop says they won't work on it because it's not worth the labor involved. I bought the engine new in 1980 and haven't used it that much. I did however use engine starting fluid a few times to get it going. Do you think the starting fluid messed it up? Is it likely that just the reed valves are sticking and that is why compression is low? If so, do you think I still have to do a complete teardown? Can you provide a complete parts list needed to do this job so I can be sure to have everything on hand when I start?

[@BrandonsGarage]

Well, dont use starting fluid- it has no oil and makes for dry starts. Low compression is probably from stuck piston rings. clean the carb and get the thing running and do a sea-foam job on it. That may clean the internals out and get it going decently.

[@paladain55]

@@BrandonsGarage How much seafoam do you recommend?

[@popstar8747]

Do you have the video available that is not sped up so I ca hear what you are saying? You were disconnecting fasteners and parts and I'm not sure what you were having to do. Thanks

[@BrandonsGarage]

Oh I ramble all the time. I speed it up whenever I say something that is useless and just taking time.

[@MoneyThao]

I kind rebuild mine but its hard to start when cold do you know why

[@BrandonsGarage]

Well, I can only guess. Carbon buildup on rings creating minimal vacuum to pull fuel until warm. Do a decarb process and see what happens?

[@curtis3653]

I'd tear my 89' 9.9 down but I'm afraid of what I might find?! 😆
