How to Remove a Johnson/Evinrude 9.9 / 15 HP Powerhead

[@nonamemannameless1600]

Thanks Brandon. I’m replacing my grommets on the exhaust gasket, and this is the best video I can find on KZbin. You and Kodibass have some great info on these old motors. I’m not sure where I read it, but blowing into the copper water inlet off the water pump informed me of my blockage. Really good info

[@The314moses]

I'm going thru the same thing right now.

Thanks, I could not figured out how it comes about. Being afraid of breaking something I waiting until I watched your video. Great job I have parts ordered and it will be up in no time. I have a 1979 9.9 long shaft great little engine. I've never worked on outboards before but my wife bought this little 14' boat, the motor and the trailer cheap. Thanks again, for sharing your knowledge.

Disseassembled my Evinrude 9.9, thanks a lot. Was very clear and throughout.

[@justinb3462]

Just wanted to say thanks. Helped tremendously to get to replace cracked swivel. Upper water tube grommet was in rough shape so good deal to get that replaced as well. Great outboard!

[@marioibarra9833]

This is an awesome tutorial. And the flat head made a big difference for me breaking the seal. Thanks!! I have a question... What would cause a slime build up underneath the area where the power block and exhaust pipe was sitting?

[@neilvandepol2903]

Nicely done, thanks for speeding up the obvious steps. Anyone know of a piston ring replacement video?

[@surfsidefishingandoutdoors]

Good video.... question.... where is the grommet/bushing for the water pump line? Mine is swollen and needs replacement

[@stephenrobinson6779]

Thanks for the preview! I would only add that there are washers under the motor mount bolts. Take care they don't fall into the lower unit when separating. I was lucky I managed to recover the escapee with a magnet.

[@jamesroberts8715]

Hi brandon will a cracked plastic peice on top of carb cause this engineto run really poorly My compression is also a little low 20 lbs lower than a good running engine i have Thanks for the great vids

[@crazyfingers25]

Wanted to do an impeller/water pump replacement on my 75 15hp johnson. Removed six bolts from lower unit and the flat head screw from shift cable. I couldn't get it to separate from and carefully used wedges to seperate the gap. The drive shaft is stuck in upper unit. Completely separated from the bottom now and completely stuck in upper..... How can i get it out. I am unsure of it has ever come out and have been researching. This is my first outboard repair experience.

[@jamesdickinson7515]

Could you do a video on replacing the internal motor mounts on a 9.9 Johnson?

[@davidbragg30]

Thanks Brandon, Easy to follow. Worked for me

[@stefangranberg6548]

Thanks for the video. I'm having two evinrude 15, one with long shaft (1991) with a bit low compression (90psi) and a short shaft (1984) with good compression (105 psi). I need a reliable long shaft motor. Is it posible to swap powerheads between those two, or is it easier to take the long shaft parts from the 1991 and put them on the 1984 short shaft, will everything fit? I'm a little worried about the water tube and shift linkage issues just by exchanging the lower units.

[@BrandonsGarage]

Whichever way you wanted to do it would probably be fine. As the powerhead needs to come off in both scenarios, I would probably just swap the long shaft kit to the short engine. This will leave both engines having their correct parts & number; thus retaining their values.

[@stephensoles3773]

On my 9.9 the gasket on the bottom end of th exhaust pipe is mostly missing, is that going to cause a running issue? Pieces of the gasket fell out when I pulled the lower leg off to replace the water pump.

[@mdbeatt]

I have a 1976 johnson 15hp that ran good 5 years ago, and I have a 15 hp 1988 evinrude that ran great until upper pivot point between motor and mount broke while on water. Can I put 88 evinrude powerhead on 76 motor? Or should I just change out plugs clean carb and what not on 76 to get it back running? what would be most cost effective and least work? OH and BTW where you get electric starter to fit a 15 hp? my disabled butt has hell of a time with pull starts.

[@joshuamunoz5036]

I have a question I have a 1986 15 Evinrude it keeps getting hot on me because I think the water ports needs to be clean, also a new thermostat,but my question is when I’m removing the head of the motor is there something special I have to do to the throttle handle ?

[@bobmacrae8395]

My 1996 15hp mercury has a kinda janky choke/timing advance for starting. The linkage connection to the bracket is not very positive. Be good if u could show how it’s supposed to be connected. Thx and love ur videos! Keep up the good work!

[@steveprice5550]

Could you do a video on converting a 1998 Johnson 9.9 tiller control to remote controls. stick steer, throttle, gear, tilt and choke? Thanks

[@joshuamaaz3797]

Awesome vid as usual! I have a 76 9.9 Johnson seahorse. I want to put an electric starter in it. Got one lying around I can purchase from you? It’s for my moms boat and she has trouble Hand starting it.

[@jimcatx3090]

Joshua Maaz u need the flywheel and the starter and bypass cover plate your better off finding a motor since parts are hard to come by good luck

[@joshuamaaz3797]

ThefatItalian66 X I already have the flywheel. Because it has a pull starter on it.

[@jimcatx3090]

Joshua Maaz you need a electric start flywheel it has 2 sets of teeth ok you can’t use the pull start flywheel sorry And u need a bypass bracket to hold the starter motor

[@jimcatx3090]

Joshua Maaz wrong maybe you should do some more research on how things work lol

[@joshuamaaz3797]

ThefatItalian66 X hysterical. But I’m looking at this video and his flywheel looks identical to mine. So I am certain it would work. Also how do you know mine didn’t have electric start once already? Maybe you should be careful throwing out jabs when it appears you may not know what your taking about. But thanks for you useless input.

[@hucknbarry3496]

I just wanted to replace the reeds but have to do this to get 1 bolt out, bummer

[@dansarette101]

I removed the power head on my 86' 9.9 evinrude and shimmed the motor mount to snug it up. Nice and tight now. But I have a question about my exhaust tube! Itvis not square in shape as all views I've seen on everyones videos. Mine is round, and does not take the square form of the replacement gasket at the bottom.mine doesn't have one. And the tube stops an inch short of sealing against the bottom of the housing down inside. Have you ever come across this? Could I PM you with some pics or something? Thanks

[@BrandonsGarage]

Usually, those would be found in a 15 HP, However, mid 80's on, you'll frequently find them in both. Nothing to be concerned with. But, you can send me an email if needed.

[@dansarette101]

@@BrandonsGarage,Thanks for your prompt replies. Yes that's right. I found this out also on a google search. And I also have a much bigger carb than what folks say is for a 15hp conversion. The throat on my carb measures 1.190" Dia. !! What is that off of? They say a 15hp carb should measure .875" and a 9.9hp - .625" Geeze, this thing's really been hacked! I don't think I'm gonna dig any deeper to check the reed valve set up at this point. It always runs great, so back together it goes! Fun Fun!

[@dansarette101]

@@BrandonsGarage Ahhh,scratch that last comment about my carburetor. I guess the .625 diameter is down inside the throat which is what mine is. But with that tubne pipe from the 15 horse I could sure get another carburetor and do the Reed valve stop spacers as well and I'd have me a 15 horse!

[@extremeboating7347]

@@BrandonsGarage Hey Brandon. I have an '88 all OE model minus the 15hp carb which was set up that way before I bought it and the reed valves which I just switched out the Chris Carson valves. Do you think the exhaust already has the round tube, and is there any way to check without removing the powerhead assembly? I'm trying to get the full 15hp conversion power out of it and don't want to leave any part of it out. Thanks in advance brother.

[@simontolstopyatenko7931]

Where do you purchase the fuel / carb hoses for these motors in long lengths? I have the 1990's 40HP and would like to purchase new hoses for all of them. Thanks

I have a mid 80s Evinrude 9.9 that I'd like to know what the sequence is for getting to the motor mounts. Can you give me an Idea? does the powerhead need to be removed first? The motor runs great, but is ready to fall off! its so bad that the sag is pulling on the throttle cable and ruined it, so gotta replace that too. Please help ! Thx

[@BrandonsGarage]

Yeah, powerhead, has to come off to get to the main mounts.

[@dansarette101]

@@BrandonsGarage right. I kinda concluded that seeing your other clip on removing the shaft extension on the 9.9. You pointed out that someone already tried to tighten up that mount under the powerhead. I've not seen that pointed out in all the clips on youtube that everyone else has posted. Great help man. Thx

[@DanPrescott]

I am having the hardest time with a Johnson 9.5 help!!! Trying to put back together and the points plate is not going back in evenly which is making the timing magneto not seat correctly then it freezes all movement. Does anyone know someone willing to help look at this remotely?

Do u just do tear downs or do u rebuild the shit u rip apart?

Pretty fkn brutal, cutting lines, and wires just because they are in the way. And then you for sure charged to replace them.

Always replace the old fuel lines.

I have a 83 9.9 Johnson. I replaced the water pump and it's pumping water. But there is water coming out at the low mount bracket just above the lowrer unit. Is it supposed to do that or is my upper water tube bad?
