Your video helped me fix my 84 Johnson seahorse 75. Had it serviced and then couldn’t get it running, floats and bulbs were flooded. Took apart the carbs and boom started right up

[@GlenB1963]

Thanks, mate. Great video. Mine is a 1978 johnson 75 stinger, and its only taken me 38 years to find one. Its coming along well but the carbies really need cleaning.

Hi , you did a video on the 70 hp Evinrude motor,. Water pump impeller! A Giant thank you! You actually, explain where to disconnect the gearshift linkage,. I have seen other U tube videos. They don't explain, the gearshift disconnect! A Giant thanks! I found it very helpful! I have found your other videos very good also! Carburetors, and trim / tilt wiring! Great work! Many thanks! 😊.

Thanks for sharing man. This applies to a Johnson 60hp which I bought used. Poor kid before didn't have a clue what he was doing. This helped me figure out the fuel line routing. ASE Mechanic by trade but these old girls get me scratching my head 🤔🤦‍♂️😂

[@darrenshafer2298]

Great video you did of rebuild of tge 3 carbs. I have a 93 70hp evinrude, I'm hoping that solves my problems as well, it seems like after choking n priming it to start all it does is spin a few times b4 it decides to turn over, never wants to start on 1st turn of the key like yours did.

[@buschfishin]

thank you! it sounds like yours are fairly clean but i’m sure there’s a little bit of gunk at the bottom of the bowls clogging the jet down there, if you’re meticulous while cleaning i’m sure it’ll start first crank after!

[@GoMidwestFishing]

So I'm not the only one who thinks an 80's motor is "new." I've owned a couple of those 3 cylinder motors. I was quite excited when I finally got electric tilt trim.

[@buschfishin]

i’ve had nothing but early 70’s motors so i’m very excited to have this one, it’s funny because i work on 2022 boats and motors and im still excited about this. love the 3 cylinders! thanks for the comment!

[@savagehandzzz3153]

That top screw you took out, on top of the front bore of the carb. There is a small jet in there yet.

[@christopherrowe2720]

Thanks for the video, probably the best I've seen. I have a Johnson that appears to be the same and it's been running in limp mode so I think the carbys are gummed up as it hasn't been used much or serviced in 20+ years. Are there any oil filters or anything on this or do I just drain the lower part of the engine?

[@buschfishin]

if you have the same motor this was before they were oil injected so it’s all premix and there’s no oil filter, you might have a fuel filter in line somewhere but if your motor has limp mode it’s going to be a newer model, the oil injected versions have an oil filter in-line with the main oil feed line. otherwise the only oil you need to worry about is the gear oil in the lower unit, glad this helped and let me know how it goes!

[@carlpaquette4687]

awesome videos! just subscribed to you and i'm excited to follow more of your videos. i've never owned a boat before but I'm close to buying a 1988 HewesCraft 16' River Runner with a 85HP Evinrude. they said everything is in good shape. would you recommend this boat for a new boater?

[@buschfishin]

those are awesome boats and being all aluminum there’s much less to worry about regarding docking and stuff like that, the 85hp v4 is a very good motor and maintenance is very easy on them it should be a very fun boat

[@captainchrisfishing]

Also the float bowls are important which one goes where the center carb has a fuel inlet in the bottom of bowl if I'm not mistaken

[@buschfishin]

i know i’ve seen them like that before, that’s a good comment. i do not believe that this specific motor has that however if a different model does hopefully this comment helps someone, thanks again!

[@Loman9711]

Awesome video! I have the same motor on a 80s model trihull 16 ft boat. Question… Since I’ve had the boat, I cannot get it to start without starting fluid for the life of me. But after it starts, it runs great! I had a boat mechanic clean all carbs and replace gaskets. I also replaced the fuel pump and filter. It’s currently pulling very clean gas with appropriate oil mixture. I previously suspected it was water in gas tank… but confirmed that’s not it. I’m priming the bulb and I know the carbs are filling like they are supposed to. It just never wants to run without a couple of sprays of starting fluid (or dare I say carb cleaner). Any suggestions??? Thanks in advance! Edit: I also replaced primer solenoid without any difference. I hear the clicking that you hear when pushing in the key.

[@jellygreen4]

My dude I've got a 70 hp 1987 Evinrude I haven't pulled it all apart like this I think was stored right but when I put the hood on it doesn't want to start it also has a steady alarm that activates after about 3 minutes of idling I think it's the overheat alert but guess I'll start replacing the senor and what no if you could drop a link for where we can get parts for this motor that would be awesome

Hi broter can you tell me how to install push start on the same motor ?

[@TravisInCanada1]

Just the video I was looking for, I have the same motor (1984) but I seen how tight those nuts were on the carbs and couldn't figure out how to get them off. I didn't think to pull the carb back to create space allowing them to get past the pins. I would really be interested in seeing that spark/ignition wire issue you mentioned at the beginning (even though you have repaired it) is there anyway you could make a video showing what the issue actually was? Thanks for the video, ya got a new sub!

I have an 88 version 70HP. Feel like it has been well taken care off but good to see this in case i have to ever clean the carbs. Just wondering do you have a video on nhow to hook up a tac? Mine does not have one and would like to see what my idle is at.

[@buschfishin]

I do not have a video on it but it’s something i’ll keep in mind for an upcoming video. If you have the red plug there will be a grey wire coming off of it, that goes to the “signal” post/wire on the tachometer. Then you have to make sure it has the SAME engine 12v and ground as the engine. The easiest way to do this is to steal it from the controls/gauge harness

[@oliverh.8785]

Hello, do all 3 carburetors use the same exact kit to order? Thanks

[@taalen90]

Would this be the same procedure on a 98 3cyl 25hp Johnson?

[@gbass7328]

Really good work. How are you checking the idle and wot ignition timing? I own a 1984 Johnson 70hp. Also fyi - I've found that those new grey line primer bulb fuel lines didn't work for me. It choked the fuel feed so I went to the new BRP available for these engine and had no issues. Another thing - I have found that E10 gas has probably deformed my choke solenoid housing and plunger cylinder. I need to take it completely apart to drill out the plastic cylinder by hand with a drill bit and sand down the metal slug. It used to get stuck but now it slides freely. I run ethanol free gas now.

[@buschfishin]

thank you! this is a great comment, checking idle is a combination of the tachometer i have hooked up on the test bench and sound (because i don’t trust my chinese tach) but it gets close enough, in the video i have it set actually a bit low, normally i would do higher because once in the water with some back pressure it’s drops down some rpm. WOT timing which isn’t seen in the video is a little bit questionable, basically have someone drive while i’ve got feet on the transom reading it 😂 - i agree with you those grey attwood plastic lines are not good long term and i plan to change them but at the time of building my boat it was all i had

[@gbass7328]

@@buschfishin Yeah seems difficult to test for but wish I could max that out safely for more high rpm hp. I have both of the OMC specs on timing if you need them.

[@cliffsmithee8195]

these motors have fixed jets so there’s no adjustment on them, if i get one in that does have adjustments i’ll be sure to make a video!

Where was the fuel leak? I have same exact motor and it’s got a slight miss/sneeze. Been chasing this gremlin for months.

[@dmac2703]

Great video! Really helping me out here bud. One question maybe you can help me with. Have 70 evinrude (VRO disconnected) it has same setup here only difference is my top carb has solo line from primer solenoid and bottom two carbs are the connected together ones. Opposite of you. Is it possible someone previously hooked it up wrong? Big difference? Thanks

[@buschfishin]

Both primer lines get the same amount of fuel, yours is probably the right way because the lowest carb usually gets the most amount of fuel due to gravity so that top single primer line will be getting the most "pressure" out of the primer. Either way it's just for starting so it's not a huge deal where they go and it should be perfectly fine how it is.

[@gdlivo3353]

My 2000 70 hp VRO Johnson has the single line coming from the bottom primer outlet and going to the bottom carb. The double goes from the top to the top 2 carbs.

[@EH-sb7kt]

Thanks for the demo! I have this same motor, but maybe the earlier version with the choke linkages. The motor is brand new to me and hasn't run right yet. My motor bogs, intermittently, when I put the throttle down. I've done the link and sync, checked the timing and same deal. Hopefully the carb cleaning will solve this! Have you done a compression test? I can't find the factory specs. I'm getting 100-80-100 (not sure about the order). Seems low to me. Anyhow enjoy the fish'n!

[@buschfishin]

yes, i originally had an older 70hp with the manual choke and i had similar problems but mine would run up to 3,000 rpm and then bog. carb cleaning should solve your issues unless there’s an ignition problem. on my old 70 the compression test when i got it was all around 100psi. this motor didn’t sit as long so it was around 140 on all cylinders. has it been sitting? the 80psi cylinder is a little low but it could be due to a lack of fuel from the carbs causing your bogging issue. let me know!

[@EH-sb7kt]

@@buschfishin the motor didn't sit around too long was used regularly on a lake. It would sit all winter in the offseason when they didn't use it. I am using a cheap $40 compression tester which, I've heard, doesn't give accurate readings. Yes if this carb cleaning doesn't solve it I would now suspect ignition and/or electrical, thx. My motor is in really nice shape it was used on a freshwater lake however there is rust on most of the cable/wiring lugs, so I'll be cleaning that up regardless. Once again thank you for the carb cleaning demo I have a lot more confidence, now that I've seen your video, really appreciate it! Cheers

did you check /replace the fuel filter?

[@Thezachofalltrades1]

What year is the motor??

[@greenlantern1174]

Thanks for the video. I have the same three carb setup on my Yamaha. Question for you. Would carburetors also cause a high idol?

[@buschfishin]

yes, on yours you probably have adjustable high and low speed jets but more likely than not a jet is clogged causing a lean condition, the proper thing to do would be to re build the carbs with new gaskets and clean them thoroughly, keep an eye out for any broken gaskets because sucking air behind where the carb mounts will cause a lean condition too

[@greenlantern1174]

@@buschfishin hey, thanks for getting back to me. I'm going to do that next. I'll let you know how that goes.

[@benjaminharville419]

Check your floats and the float pins. If a pin gets stuck inside the jet and doesn't freely fall down as float goes down...it will cause a high idle

[@Comraduk]

Small correction. Two strokes suck air in when the pistons are going up to the compression stroke!!! not down!

Por favor ver el video en el minuto 4:35 ahi doy la explicacion, gracias!

[@gdlivo3353]

1 quick question. The service manual says to replace the 6 bolts holding the air intake / silencer base plate to the carbs every time they are removed. It also says to replace the cork gaskets, but let's not worry about that. I notice you didn't mention replacing the bolts, so I assume you re-used the originals. You didn't apply thread lock, which is pre-applied to new ones, and still evident (blue) on mine. Is this completely unnecessary? With OEM bolts @ $9.95 a piece, I doubt I'll be replacing mine either.

[@buschfishin]

The idea is that with the loctite the bolts can never vibrate loose making the cover come off and letting stuff get sucked into the carbs or that a bolt doesn’t fall and get sucked into the intake. I personally don’t replace the bolts unless they are corroded badly but I also have never seen them come loose if they’re tightened especially when they’re threaded tight into the plastic.

[@jstorres486]

Thank u for the info.. can you do this to a 1990 evinrude 90hp?

I have a 1980 version of this motor in 70hp, great motor. Probably the toughest outboard I've ever had.

[@Slave4UMrs1]

Hi 1 question,i saw you are using a tachometer same as mine. At what number did you set the internal settings?

[@buschfishin]

i believe it is on the two setting but i would have to check, i did not change it from the factory and i’ve noticed it only revs up to around the 3k mark, mainly use it for the hourmeter

[@andysmachado4210]

My Johnson 70 only runs off the solenoid, what could be the problem with the carbs because I've already did a carb kit for them, Thanks

[@buschfishin]

if the motor only runs with the primer solenoid engaged, the issue is lack of fuel. If it were me (i know this is going to suck) but i would take the carbs off again, take the fuel bowl off and take the drain plug out. first stick a needle in where the drain plug goes and clean out the jet in there, i would also verify that the floats are installed properly and not upside down i know it sounds dumb but it’s been done a lot before. i would also do the test i did in the video where you hold the carb upright and blow into the fuel inlet port and manually move the float up and down to make sure that it is opening. obviously make sure that the float pin, float seat and entire fuel inlet portion is spotless. another possibility would be making sure the little gasket that goes around the venturi pickup tube is installed. at that point and after making sure everything is spotless put it back together and try to run. make sure to pump the primer until it’s hard and if ir does run, make sure that primer is staying hard. check valve in the primer going out can cause loss of fuel pressure as well as a failing fuel pump.

[@buschfishin]

Make sure that you are getting good fuel flow, most of the time if it's dying under load it's a lack of fuel. Could be clogged jets in the carb but if you have already gone the fuel route make sure that you're getting spark on all cylinders

[@cstepanuk1014]

How do I adjust the butterfly on one of the carbs? At wide open throttle carb #2 buttery fly isn't open all the time

[@buschfishin]

on the linkage for the three carbs there should be a set screw that attaches the plate to the linkage for the butterfly. if you loosen it up just a little bit at wide open and then hold the butterfly to where it matches with the other two you should be able to tighten up the set screw and have them in sync

[@froggerman44]

So what is the difference between the 75 hp and the 70? How do u make the 70 into the 75?

[@buschfishin]

i believe the difference is really the port tuning in the block and you might get 1° timing advance on the 75 and slightly higher rpm, your best bet would probably be propping it to turn higher rpm if you’re looking for some more speed

[@Veemack21]

Can you install the float upside down?

[@buschfishin]

It’s possible to do it but what will happen is the engine will run and idle and even be good up to the mid-range but at WOT it will surge really badly because the float bowl will fill up and the engine will rev up but it won’t fill with enough fuel to keep it running at WOT.

[@dougnpc]

31:17 would this apply to a 2000 model 70hp Johnson?

[@buschfishin]

that time mark is at the end of the video which part are you referring to?

[@cichlidbabys4841]

Bushman what do you set idle at how many rpms

[@buschfishin]

out of water set the idle at 900-950rpm, once you get in the water it will drop down to around 800, that should be about right so that when you shift it doesn’t clunk too hard but also doesn’t die when in gear, if it does raise in half turn increments just until it doesn’t die when you put it in gear in the water

[@cichlidbabys4841]

Thanks for taking time to answer

[@ClintClarksondp]

Do u use blue loctite?

[@buschfishin]

Yes on the float bowl bolts if they don't have any on them I usually will add some. These had a little bit on the threads and even though its dried its enough to hold them in. No need to add a whole shitload on there it'll just make it more difficult the next time they need to be taken apart.

[@user-rz7hq8ln1p]

Do u work on 90hp evenrude

[@buschfishin]

I have a video on the 90hp, removing the powerhead but I didn’t end up getting enough good footage to post the assembly. I do have videos coming on a v6 200hp though!

[@rustrescuetv]

is a 1975 evinrude 70 hp motor the same as your is

[@buschfishin]

the carbs are pretty much identical but on a 1975 most likely you will have a choke solenoid and an actual choke butterfly and a manual choke and all the linkage that takes where this motor has a primer and none of that. all the internals are pretty much the same as well as the lower unit and all of the linkage.

[@rustrescuetv]

if I were to spray gas and oil mixture strait into the carbs would it al least run for a bit or does that not work on outboards?

[@buschfishin]

yes, if you spray some down the carbs and it runs when spraying but doesn’t run if you don’t spray it then that indicates that there’s an issue with the fuel system, most likely the carbs are dirty and not allowing it to get any fuel

[@rustrescuetv]

I rebuilt the carbs already, and changed the fuel pump but seems like the fuel pump I got was bad so no fuel being pumped into the carbs....

So parts cleaner eats rubber but not paint

[@buschfishin]

parts cleaner will break down the wax surface of the rubber and cause it to prematurely wear if it’s moving or cause it to crack and dry out sooner over time, won’t dissolve immediately, won’t destroy paint. will destroy powder coat though
