How to Remove a Flywheel on a Johnson / Evinrude / OMC Outboard Motor 

Thanks! I’m 13 and I finally can take the fly wheel off my 1948 5hp Johnson outboard. Thanks again!

I know some people disagree, but, you can use an impact driver to remove the flywheel (on the center bolt of the puller.) Some are easy to remove, some not. Same with most magnetos and flywheels on these engies, motorcycles, atv's, dirtbikes, etc.

Awesome video. Thanks for the lesson because I've never done it before. This is the next step for my 1959 35 hp Johnson Super Seahorse restoration.

I still gave you a thumbs up bud. Thanks for the help... I broke bolts from the wheel puller... so just so your viewers know you sometimes have to take the pulling bolt to max tension(before the puller bolts break) then hit the top bolt with a big hammer to introduce shock to it. That's a lesson the old man at the dock taught me over the phone here in Virginia Beach. 😎

Awesome instructional video. thanks for the great information. Learned a lot just now.

Awesome. Exactly the instructions I needed when I needed them. You rock. Go Air Force.

Something I learned pulling my 27 year old 200 Johnson, only loosen the nut a couple of turns to keep it from coming off violently, add anti seize to the threads of the center of the puller (it keeps the threads from binding against the puller, only way I could get enough pressure on it), and you may have to give the center bolt of the puller a good tap to pop it off.

You've got to have the right tool for the job, Beavis.

Thanks for the strap wrench idea! Worked like a champ for the flywheel on my 85Hp V4

If you put the nut back on the crankshaft with about 1/16 inch clearance from the flywheel before wrenching on the puller, it will prevent the explosive release of the flywheel.

Flat head screw driver through slot on flywheel against starter. No strap needed. Much easier then finding a strap tool

Just a tip for those that might not be aware of it, don't turn the flywheel counter clockwise because it could damage the water pump impeller.

thanks for making the video! my Johnson 5.5 1954 had terrible ignition coils and wouldn't run good but with you're tutorial i got off the flywheel! thanks.

I got a harbor freight fly wheel puller and 3 -6 inch bolts 1/4 -20 bolts at a hardware store and a impact with a 3/4 socket and a rubber Mallot

if there are bolt holes in the fly wheel you can also use a wrench steel tube or rebar to undo the flywheel nut just hold it between the 2 bolst and set your tool for the nut so you can squeeze the 2 tools togetther an the nut comes off

After running to Tractor Supply two days straight to find the right size bolts, I finally got the flywheel off using your method. It was tough and it let out a loud BANG! Sounded like a .38. It scared the mess out of me.

You don't need the flywheel strap holder thing. If you have an air gun. And you don't need to use the holder when using the puller to get the fly will off

Thank you man for showing me how to do and how to do mine thanks a lot

I pulled a spark plug, ran the engine to almost TDC and filled the cylinder with 1/2" diameter rope to fight the counter clock wise rotation of the engine as I unscrewed the flywheel nut. Worked for me with no strap wrench.

I have removed fly wheels off of 90 hp mercury and if you did not leave the the nut on some you would either get knocked out if not majority injured or loose some fingers. Remember the that center nut on some on better out broad motors for safety.

That's bro very good info I dont have to pay anybody to work on boat outboard

Do you have a video for reinstalling flywheel? From a fellow A/F vet. Thx for your service!

Very Good...

How do you put the flyweel back in and put the timeing back

U need 3 - 6 inch 1/4 20 thred bolts

You don't need a strap Ranch just a piece of ropen you know what you're doing

nice vidieo thanks 4 the help

great vid thanks

If you have a recommendation for the strap wrench - they are not easy to find with a long strap - please tell us either how you made yours or where you got it.....

I have a 1992 johnson 15 horse motor. I bought a power pack on Amazon that said it was the right size but the flywheel would not fit over it. Now I've bought another power pack from Sierra and still the flywheel will not seat when I line up the groove in the center of the flywheel. The old part is made a little different and it will fit. Is there a special procedure to get the flywheel to clear the power pack?

thank you

I did not run this motor since last summer and fully expected it to run after doing the carb and throttle cable.I put my 1988 9.9hp back together and flywheel was last and now I have no spark.My lanyrd switch seems to ohm out ok and is open contacts.Could I have done something putting flywheel on?I just slid it on the shaft while lining up keyway.Torqued to 45FTLBS..

I have a 1972 50 hp evinrude and can't get flywheel off? I tightened the bolts on puller until you could not go any more! hit with hammer and it never come lose?????

how do you clean whats after the flywheel after wards, because i can't get my throttle to move at all, i know i need to order a new throttle cable, could you maybe post a video of you doing that.

what size (3)bolts was it for the fly wheel /harmonic balancer puller???

hey i have a 95 evinrude 112 spl it cranks over fine but i seem to not be getting spark i was gonna pull the flywheel to test the stator if you know of anything else that might cause this before i try to replace the stator i would appreciate the help the motor has new spark plugs and it was running fine about 6 months ago.

Engine.... Not motor

Impact is your friend

50 hp Mercury, 4-cyl. whats the torque for the flywheel nut, when replacing ?

Do you have a video showing how to reinstall the flywheel?

How long should it typically take to pull the flywheel?

WHAT SIZE SOCKET FITS A 9.5 EVINRUDE ..1976,,,1.5/16 IT CALLS FOR ...BUT THE SOCKETS I SEE WONT FIT IN THE RECESSED FLY WHEEL ,,,A PLEASURE TO SUB YOU

Thank you where is Highland outboard located?

Once you pull the flywheel off is that a woodruff key on the shaft ? Mine is have worn off , can’t get ahold of it to remove it ... any ideas?

What size are the 3 bolts

do you have to do timing again if you remove and replace flywheel

My flywheel snapped and the center is still on the shaft. I need some ideas for how to remove the center of the flywheel???

Hello, I have several old Evinrudes and Johnsons, but on two of these, a 1953 3hp and a 1961 3hp, the flywheel is really stuck. I've tried everything to get them of. I've tried a puller and on the '53 I tightened the puller so much I cracked the crankshaft of the engine. I've also tried the more simple methode, with a screwdriver prying the flywheel up and with a hammer tapping the crankshaft down. Neither of these methodes worked. Can you give me some tips?

93 model 50 hp evinrude . motor spins over fine getting fire to stator ...getting fire to power pack but from power pack to coil pack I'm not getting any fire ....has automatic oiler but oil tank is cracked . can I bypass the oiler safty switch and use mixed gas .

I have a 1988 9.9hp Johnson tiller and since I have owned it amybe 5 years now and when first purchased the throttle was and can be very hard to get up to full throttle.It seems to be very hard to twist and won't move past half throttle and my suspicions are the part rotating under the flywheel which has the cam that contacts the throttle roller for carb.Can these get gunked up or something that would make it hard to rotate?First time I ever used it was afraid of breaking something and then I felt it pop kinda and it went to full.Any experience with this?

I have a 90 9.9 evinrude flywheel will not budge even with correct tools any ideas.

i need a blowup of the fuel pump to put it back together on my 6hp johnson outboard

i have a 1998 evinrude and i got my fly wheel of before and now idk what happened but my crank shaft nut is totally stripped along with the crank shaft bolt as well im shit out of luck any ideas i dont know how to replace the crank shaft anybody know any videos ?

Today I attached the puller tightened the puller with a wrench Wouldn't budge got the impact wrench and stated again slowly the socket started to turn and the flywheel came off But to my dismay the flywheel came off but he hub was still attached to the crankshaft The flywheel had ripped away and destroyed the flywheel Ever heard of such a thing? Lucky I was replacing the flywheel with one that had a ring gear.

thanks man does the stater stay on the fly wheel ?

byan
