1973 85hp Johnson. How to change the water pump using brand New Kit! Countdown to 1000!!

[@paladain55]

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.

[@BlackoutBilll21]

glad you liked!! thanks for commenting!!

[@skeeterjeff2012]

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.

[@BlackoutBilll21]

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!

[@calebwinterbottom196]

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!

[@BlackoutBilll21]

@@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 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.

[@BlackoutBilll21]

ahh!! been there my friend!! Hey now you are at least a carb expert!! Thanks for commenting!

[@obxarms7685]

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.

[@BlackoutBilll21]

kepp em coming my dude!! lol thanks again!

[@mtgsurfer]

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!

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

[@BlackoutBilll21]

Thanks again!!

[@delaneyelliott837]

I have a 72 65 hp Johnson- you can use muffs but you need to get the ones that have water flowing to both sides. Also, these motors don’t have true tell tale, but they do pee water out of a hole on the front side of the lower unit. Since nothing is coming out of yours I would guess either the muffs aren’t getting enough water into the motor or you have some kind of blockage in the intake.

[@BlackoutBilll21]

yeah this motor was the muffs 100%. the overheat alarm would go off when testing but in the water no issues at all

[@BG-gb3vi]

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!

[@BlackoutBilll21]

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

[@davidtaggart8736]

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.

[@BlackoutBilll21]

never thought of that! thanks for the tip, watching and commenting!!

@@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!

[@kevinrowlett9408]

What's the alarm sound like? I've got the same motor

[@obxarms7685]

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.

[@BlackoutBilll21]

fantastic advice! thanks my guy!

[@kevinanderson9243]

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

[@BlackoutBilll21]

i hear ya my man!! THANKS FOR COMMENTING!!

Probably why my overheating alarm came on after ten minutes on the muffs!!!

[@BlackoutBilll21]

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

[@texnsfan04]

So why not use muffs? I have the kind that puts water into both inlet ports of the engine

[@BlackoutBilll21]

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]

@@texnsfan04 thats awesome! thanks for the update and information!

[@MattSchwanda]

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.

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.

[@hugoglenn9741]

@@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!.
