You sir we're the only guy that said anything about turning the flywheel to get the shaft to drop out, I literally moved it an 1/8 of a turn and it fell right out, I was super frustrated until I watched your video! Thanks so much! Randy from Michigan.
@@bobhammond8926 Shine a light, & lookup inside the exhaust housing. Notice the orientation of the slot the roll pin has to go through, then turn the driveshaft to be close to that orientation. Then, when you push the lower unit up, you should only have to turn the flywheel a small amount & it will go right up.
I just started doing a waterpump on the twin to your motor. Having done hundreds of pump jobs I dove right in. Everything went fine until I tried to extract the lower unit. While pulling I could feel the spring but was unfamiliar with this model. First I went to a parts cattalog to see what was up under the powerhead that could be causing this condition. Second I went to TH-cam and found this video. You did such an excellent job showing and describing I immediately subscribed. If it weren't for this video I would have removed the power head next. Unlike your motor, this motor has very, very low hours in fresh water. I will consult with my customer about freshening the seals under the powerhead and recomend this video. Thanks for a great video. Dave
Awesome Brandon. The first clear explanation of this part of the lower unit I have seen. I have a 66 in near new condition I want to reseal with new gaskets, o rings etc...
This is just a great explanation of this motor which are way different from the usual tear down. Also when shit happens as it does with ANYONE, he does NOT edit it out so we can look out for things.....great video!
How much can stay on the powerhead when removed from the housing? Flywheel? Carb?, Recoil Starter Assembly?, ...? That would be helpful to know if servicing the crankshaft seal when doing the waterpump
Just picked up a '77 Evinrude and will be doing this! Great video, very useful information that's a "must know" rather than forcing it. On my engine there is no kill switch on the front and I noticed yours has one along with others. Some do some don't. Was that an option? I don't have a kill button on the end of the tiller either. Haven't ran it yet so wondering if the kill switch is integral to the twist portion on the tiller handle?
@@BrandonsGarage thanks for the reply! This ones a model 6704M #J0005608 ? This one does not seem to be just simply missing it either as thee is no cast boss in the lower shell for one either
very good so i pulled the power head can we still get all seals for upper drive shaft and i need a water pump kit /////ya vid 10 out 10 /////Ps where s the exhaust gas go when you look at it its blank no big hole down the trunk ??????
Thx for video. I have a 1963 evinrude 5.5 fisherman that sat long time. Rebuilt carb and got it running but now leaking oil from weep hole so I think seals are bad ( drive shaft seal??). All pry need replaced. Not sure how to tackle and no 5.5 videos. I’ve read 6 hp was similar to 5.5. True? Is the lower unit essentially the same and I could follow your video ? Thanks in advance

Johnson 6 HP 4 Stroke. Model J6RL4SU: Gear shift handle is stuck. removed lower unit gear is free and shifting ok. removed the handle from it's square bar. trying to remover the PVC that is connected to a wire which prevents starting the engine while in gear (pull start) my question is looking at the leg screwed to the power head, does this come off without removing the power head from the housing or disconnecting all the other things connected to it?
Can you mention why you went to reverse instead of forward? Also I guess I can just rotate the propeller to find the roll pin slot since I won’t be taking mine off??
Sir Brandon. Thank good video. I have a Johnson 6hp 1977 Question: How can we explain that the roll pin, spinning fast with the driveshaft, does not tear or scratch other parts. No oil or grease in the area.
I doubt this will get a response but hey. I'm new to this whole ordeal and recently purchased a boat with the 1964 version. Everything seemed to be great with the motor but it was not pumping water. Almost all of the seals in this video on my engine were shot. And even the seal around the line to the water pump was shot. I'm pretty confident this is why I was not getting water. But would this explain what I feel is excessive blow over of oil and gas? That was coming from the weeping hole for the pump nothing extreme but it was evident
I had the same problem 6 87 cents plus shipping for that pin wasn’t pumping water the rubber impeller looks good but I ordered a new anyway thanks for the information good video
Hi I was just given a Johnson 6hp by my neighbor, it runs just has a very rough idle and shuts off we can see air going through fuel line and not getting enough fuel,we’ve replaced and rebuilt everything we know to do , fuel pump, gas lines/clamps, carburetor,and new float and everything.only thing we haven’t done is change tank which is going to be done tomorrow any advice?
I have the 5 hp with no shifting linkage.I pulled the lower unit didn't have to twist the shaft,all the seals and spring came down with the shaft.Is this normal on the 5hp?
Thank you for this video. I did receive one Johnson 6HP workhorse. The same you showed . Sadly it's block is seized, the foundation rubber are damaged. The swivel bracket jammed. It was sitting in t owners hoise for over 10 years without use and no flushing done. It's here in Goa, India with me
“Put a wrench on there to make life easy”. 5:44 Remove the sparkplugs & make life really easy. You’re going to turn the flywheel during disassembly & re-assembly…& if you’re doing a rebuild, probably replacing plugs anyway. Remove them at the start, the flywheel will turn with two fingers.
I have a evinrude sprotwin 1965 9.5 hp. The driveshaft is stuck in the powerhead. It doesnt appear to have a roll pin in it looking at the parts diagram online. Any suggestions on how to get it out?
@@ollyboo Got it off eventually after trying everything else I could think of. Laid down the motor horizontally with the prop facing up and soaked for days between the prop shaft and prop with rust breaker spray. Used a butane torch to really heat up the shaft to get the liquid boiling to help penetration. Lifted up the motor slightly by holding onto the prop and hit the shaft end square on with a hammer a bit at a time not overdoing it but it moved a little bit each time. Kept spraying and hitting until the shaft end was flush with prop. Then got someone to help and hold the motor up still by the prop while I used a drift to keep hitting at the shaft. Eventually the prop came off and it was corrosion that had been the problem. Cleaned up the shaft and inside of the prop, put in a new shear pin (the one in it still looked OK though), lubricated and reassembled. Don't know if this was the correct way to get it off - I'm not a mechanic, don't know if any damage was done, haven't taken it back out on the water (it's a second motor) and haven't done a gear case pressure test in case any of the seals were damaged. Will check one of these days...
My all time favorite motor! Although the reed petals seem to wear out and start to leak after 40 years of every summer use. A question: do you recon that engine would work with glassfiber reed valve petals? Is there enough vacuum to open stiffer petals? Where i live, new petals are pretty hard to get without ridiculous postage costs. So i'm thinking about a diy way from a sheet of reed petal glassfiber.
I had mine out on the eater the other day and my shifter malfunctioned.. I could move it forward and toward neutral but it was all play. It wouldn't engage. So I jammed it in reverse and had to drive back to the dock in reverse. 😂😂 I'm probably just gonna get it serviced by a pro after watching this teardown. 😂
Well thats not good. Remove the lower and hope that it rotates. If not, remove spark plugs and see if you can peek inside and see rust. Or, remove the flywheel and hope something under there came loose and got lodged. If not, remove the cylinder head and peak around. Hopefully it doesnt look like this thing: th-cam.com/video/3pjasly-xZE/w-d-xo.html
hello I have the same engine and I would like to know if you can give me the number of the spark plugs? they are not on my engine and I don't know what to put. it will be very kind of you. have a good day.
Does anyone have a link to where I can find the 2 gaskets needed? Also having issues finding that pin for the crankshaft.

Only thing different is you have to remove the powerhead to remove the lower. I have videos on 5.5s as all.

Question: How can we explain that the roll pin, spinning fast with the driveshaft, does not tear or scratch other parts. No oil or grease in the area.
it grabs the lower plate, spring, and washer.
All of it slips.
And, it does sometimes tear up parts. I believe the goal is to tear up the cork washer.
That’s a sweet workbench for outboard repair!

That probably unburnt fuel/oils slowing dripping out.
Its common after use to find a little puddle of black oil under the motor later.
@@BrandonsGarage thank you a million times! And wow that was fast.
What’s the part no for that 3 blade prop
While you were pointing out the slots where the roll pin fits through you can see the marks where the previous guy forced it.
What exactly does that roll pin do? Does it join different length shafts ???
Nope, just compresses the seal.
And that shaft spring seal, would that be considered a mechanical seal?

@@nickhendrian7451 keep pressure on the lower crankshaft seal.

I have a 1975 with a broken roll pin. What is the purpose of the the roll pin apart from making it difficult to drop the leg off the motor?
its pushes the lower crankshaft seal into position, and keep retention on it.
Quite an important pin.
