Thank god you made this video. A year ago when i was trying to do this on a donor motor there was no resources whatsoever.
glad you liked!! thanks for commenting!!
One more bit of advice...the top of the shift rod where the "scissors" connect has a blunt side and a side that has a sharp edge. That sharp edge was made as a ramp to push those scissors around. Knowing that makes it much easier.
kepp em coming my dude!! lol thanks again!
I just replaced the water pump on my 1975 Johnson 115HP Outboard. I wish I would have stumbled upon your video before I did. Would have been helpful. I ended up taking off the carburetors.
ahh!! been there my friend!! Hey now you are at least a carb expert!! Thanks for commenting!
Ok I have worked on these motors for 40 years. There are two things I see that caused your over heat. First you don’t have the muffs on correctly. The rubber cups should be vertical, you have them horizontal. Notice how the water is just pouring out the back, prop side, of the muffs? They need to fit tight to the case. Now the round muffs is what I used for years, and still do, never any issue with overheat whatsoever. Just remember they have to fit snug to the case, or the water cant be directed into the water pump.
VERTICLE!! awesome! Never thought of that!! Plus These rectangular one NEVER fit tight! Thanks for the expert advice!! You should subscribe and comment you wisdom on all my videos! lol Thanks again!
Wow, now I’m thinking my evinrude motor is ready to take out on the lake. This helped a lot! I have been stuck on this for so long. What about if my primer bulb becomes soft after running for A few minutes, to the point where the engine won’t get any gas I don’t think. Because I have to keep pumping the bulb once it starts to keep a good flow going. What could be the issue there? Thank you!
@@calebwinterbottom196 You most likely have air in the line. I would make sure your bulb is facing the right direction! also make sure your tank is vented!. Finally try a new line and bulb. If that doesnt work check your fuel pump/ or your carb could be dirty
I have a 1984 115 hp evinrude and I use water muffs after I put a new water pump on and the tell tell was working great I also replaced the two thermostats good job thanks again for the videos
Thanks again!!
Thanks for this video. I couldn't figure out how to get the shift linkage apart. I also didn't know about the dual port exhaust not self priming on these engines. That explain why no water was comin out. lol. Thanks again!
happy to help!! anything else you need just ask!! please consider subscribing and THANKS FOR THE COMMENT!!
Dude, thankyou so much
my pleasure!! Good luck with your project!
You did that Audi dirty my man! Haha 😂 Great work as usual learned a few.
Haha my poor a6 😂🤣😂
I have a 74 70hp evinrude. The muffs work great for it. You do need to put hose on the right side of water inlet. I let the water run for a minute or two before starting engine. Then once the engine is off i let the water run some to flush hot water out.
never thought of that! thanks for the tip, watching and commenting!!
I have a75 40hp muffs work great
@@trophytines cool! Yeah I don’t know why mine suck! But as stated above I probably did it wrong / have a crap tool! Thanks for the comment!!
@@trophytines so muffs on my 1972 50hp should work fine right, it sounds the alarm after being on for like 10 minutes? Maybe I just need to actually have the motor in the water haha, or a big bucket. This video would have helped me so much at the start of the summer when I first got the motor, been trying to figure out why it sounds the alarm all summer. Thanks!
How is hand on the fly wheel while it's running??
not sure what you mean my man. Let me know Thanks for watching!!!
Next time take the plate off that holds the shifter and throttle rods in place and pop them out . MUCH easier to get that pin out.
fantastic advice! thanks my guy!
does the boat have to be in a certain gear when removing the lower unit and reattaching the lower unit? Did your driveshaft insert easily into the motor when you reattached the lower unit? I cant get mine in flush!
it went in pretty easily. You should see the top of the shift rod come through the opening. if its not flush you probably missed
Thanks for this video would love more help me out a lot
Glad it helped

I appreciate you my guy! keep me updated on that fuel line issue!!
Got the same motor...was wondering why I had very little water trickling out while using muffs..thanks!
Omg!! Right after we installed his.. we ran it on the muffs in the street and he got the alarm too!!! Took it on the water and it worked great!!!
@@BlackoutBilll21 this is exactly what’s happening with my 1972 50hp evinrude. I bought it at the start of the summer hoping to use it atleast once, but that damn alarm scares the crap outa me haha. I changed out the water pump housing and the water pump impeller, but with muffs on it still alarms after 10 minutes or so. Now I’m thinking I installed it all right and just need to take it out to the water to test… maybe the muffs just suck. Thanks for the video!
What's the alarm sound like? I've got the same motor
These motors are not self priming. Basically if it has a single "pee hole" you can use muffs but if it has the dual exhaust ports like this motor (I have a '77 70 hp...same thing) then you MUST USE a barrel or drop it in the water. Very frustrating but you might burn your engine up otherwise! Hope this helps. Cheers
i hear ya my man!! THANKS FOR COMMENTING!!
Probably why my overheating alarm came on after ten minutes on the muffs!!!
its very possible!
@@Spiff178 did you figure out what was happening with your alarm? I’m having same issue, but I have not tried my motor out in a bucket yet. Or even in water for that matter, I’ve just been trying to use muffs but now that I saw this video and all the comments. I think it’s just needing to have better water flow. Gonna take it out in a week or so and see
Hopefully I didn’t burn up my brand new water pump kit that I put in…
how often should you change a water pump? Thanks for video
Anytime!! Thanks for the comment! And hope you sub!! I recommend every 3 years but I know people like to go every year. I do 5 years but I know when the motor doesn’t look / sound right
@@BlackoutBilll21 thanks

Viejo mefalta comentarte algo eese modelo de motor ocupa yevar los termostatos para ketire agua porke yo selos kite nose si eso afecte ke no tire agua
it does have a little spinning finned wheel... but the water pump should be the thing drawing water up into the motor and out.. I would check all your passage ways and make sure your water tube is lined up correctly. Force compressed air into the outlet tube also when the motor is running
Hey man I have a 94 v4 115 with a brand new water pump will not pump on the muffs at all
can you get it to a lake to test? maybe keep it on the trailer?
they make different types of muffs.. make sure water is high enough pressure!! also make sure nothings clogging the works either
I blowed air threw all the lines
I have the cheap $6 muffs from walmart
@@brandone6252 try Amazon for the better fitting ones. Did you change the water pump? Verify that it’s good? Or are you not pumping water and assuming it’s the muffs?
Another top video mate
With these 60s-70s models it's about water level, muffs don't really work needs to be in a barrel as you know, water level roughly at cavation plate roughly 👍
Thanks mate 👍
THANK YOU!! yeah im starting to realize that bout the water level! its funny how I Bought those muffs and NEVER get to use them lol THANKS FOR THE LOVE!!
@@BlackoutBilll21 PS the impeller you helped talk me with was something seriously wrong but sold the motor did and did another one too easy, legend thanks
Brisbane Plants happy to help!! Thanks for the sub!!!
Do you know the prop size on the 115
ZERO idea lol sorry. check out this link and look up your year and motor it should have prop sizes and part numbers

Do not put gasket sealer. You will rue the day when the gasket sealer gets sticky friction between the impeller and housing thereby burning the impeller and repeating the job.
Ive never head of sealer causing friction and burning up an impeller. if anyone ever burned up and impeller, the sealer wasnt the problem
even still thanks for watching and commenting!!
@@BlackoutBilll21 the clear silicone that was used as a sealer was definitely the problem. Anything the gets between a rubber I’m-teller and stainless housing other than water or grease causes friction and drag. That means heat and premature filler. If the manufacturer doesn’t call for,it never think you are smarter than the engineers unless you have a good reason to do so or there is a paradigm shift.
One such paradigm shift is how everyone (like Jiffylube, etc) says change your oil at 3000 miles. That hasn’t been true since the 1970s and all cars exceed the interval nowadays. All you are accomplishing is throwing your money down the drain.
So if it doesn’t call for it, DON”T do it!.
Great video 👌 Where did you bought the water pump kit?
the owner bought it off ebay.. I can tell you it wasn't easy to find and they sent him the wrong one originally
@@BlackoutBilll21 I'm working on a 1972 Evinrude Starflite 100 hp and man it's hard to find parts for that particular year and model
i hear ya!
How do you flush that thing then at home after salt water use?
So I’ve been told that these particular Midas are crap! They make ones that seal better/ maybe position them up and down instead of sideways!!
@@BlackoutBilll21 Got it, thx!
@@alexcruz7719 any thing else I can do to help let me know!! Thanks for commenting!
Do you happen to have a link you could send me with the whole kit you got? Having hard time finding one.
This one was tricky., I think I went to marineengine.com. Give me a day I'll try to get you a link!
www.ebay.com/itm/154565821782?hash=item23fcd74556:g:ZGEAAOSwV0ZhE~51
or go to ebay and search these part numbers.. 389642, 389157,317805. hope this helps
Thanks for the reply and help!

Eske estoy batayando para ke metireagua nose porke nometira agua
see below
Negative Batman. Always non hardening permatex between the impeller plates.
lol sorry robin! I disagree :) respectfully
So why not use muffs? I have the kind that puts water into both inlet ports of the engine
so you can try that however for some reason multiple people I've seen with this particular engine.. they don't work!. So if the both sides type works please let me know!! but it has to be on the 69-73 85hp motor! This guy used muffs and it wasn't pumping on a brand new pump... however in the water it worked perfectly.
@@BlackoutBilll21 mine is a 78 model 85hp maybe that's the difference, I use the double muffs and my motor pees the water out everywhere its supposed to
@@texnsfan04 thats awesome! thanks for the update and information!
There’s no reason that you can’t use muffs on that motor. Any motor will need a good seal in order to prime the pump (if the water pressure is too low) otherwise it will just suck air. Use an adjustable bar clamp to get a good seal on the water inlets…..
Some smaller horsepower engines with the screened inlets will need the pump to be submerged to be primed and you wouldn’t be able to use muffs…..but this motor can easily use them.
@@MattSchwanda I run my 78 85hp evinrude on muffs quite a bit and never have problems with it
Hola hoyga ocupo partes para un 115 evinrude aver si algien mepuede ayudar donde puedo en contrar
I used translate to try and figure out what you ment... If you are looking for parts for your 155 evinrude try ebay!! Good luck sir and please consider subscribing!!
I have the same motor and I have the round muffs and there is a hole drilled in one of my bolts that holds on my bottom end that pee's out water and also one hole on the left side of the engine and front of engine that squirt out water and a little out the exhaust ports on back of the engine but not always them ports are relief ports. you want to see water and exhaust spraying out the center of your prop. also my engine is a 1973 85hp Johnson hydro electric drive.
Gotchya!! Thanks for the input! On this motor we saw water coming out of other places but his overheat alarm was going off still and the engine was HOT!! lol but when he got in the water it was cooling quite nicely!! Thanks again for the comment!!
@@BlackoutBilll21 Good to hear it worked good once in the water. I am working on mine again. after being stored all winter my fuel pump is leaking fuel everywhere so new fuel pump time. but these engine seem to run forever with some work.
@@jamesclaxton1988 hell yeah! always reliable and rebuildable!
Question is that a 2 or 4 stroke motor .
2 stroke
I just bought a motor and it looks just like this one and so confused as to if it's 2 or 4 stroke
The guy I bought from says it's a 4 stroke no need to mix fuel any idea were I can find out for sure b4 I burn out the motor or damage it
@@cabezong3204 this year this motor was def a 2 stroke… if yours was a four you would see an oil tank or a spot to separately fill with oil
I don’t want to give you misinformation about your motor… can you give me a model number?
Where did you buy the kit?
The owner of the motor actually went to a marine shop. I usually find all my older outboard stuff on ebay!
Where can you get a new impeller?
ebay most likely or marineengine.com
Is your motor a 2 or 4 stroke
Sorry, 2 stroke
I'll just bought the same motor how do you tell if the motor is peeing or not since there is not Telltale
on this motor and most older ones... the exhaust holes is where the water will come out. Not a steady stream but more like gushing or in heavy spurts!
There is A8 inch pipe plug on top of the cylinder. You'll see it, it's just the plug. You can take that plug out. I think it's on the right side of the motor on the top of the cylinder Take that plug out and install a fitting to run a p holds. That's what I did with mine and it works fine
1/8 inch pipe plug
Good job Bill.Hope you didn’t scratch the neighbors car using it as a work bench.😳I am surprised the new impeller didn’t get ruined,but I guess it was staying wet.
hahah yeah Thats my $650 audi! fun little 5 speed that I dont have to worry about the paint! lol Yeah I believe water was in the housing so when he ran it on the water it worked great!
The water hose has to be on the right side.
interesting! Ill try that next time! thanks for the tip~!!
Viejo mepaso lomismo mo.etiro agua un 115 ygual kefue loketenia
I would check the water tube or the thermostat my guy!! thanks for the comment... hopefully you can translate this
Hack job at best.
thank you?? LOL
dont forget to sub!!
Sounds like shit, its misfiring Ya need to check one of the points, or the carb is not properly adjusted right ,its popping and only running on two cylinders
the video might sounds bad but it sounded great in person!! like a big block chevy!! lol Thanks for the comment though! and watching!!
Out of water there is no back pressure on the thru hub exhaust. It will always sound a little rough.
@@MattSchwanda great point!
