Johnson 9.9 water pump replacement 1987

How to replace the water pump on your 9.9 Johnson. This is a 1987 outboard motor.

[@dadams19111]

You video helped me. I have a 9.9 that I inherited from my mother in law and it hadn't been ran in 20 years. Your video's help me and saved me bucks brother.

[@Michaelsbackyardmarina]

That is great news. Thanks for watching and commenting.

[@AaronS11979]

Pro tip: an easier way to put the new impeller into the housing is to first install it on the drive shaft. Then "screw" the housing onto it in the correct rotation. The impeller will slip right in with minimal effort and be centered on the shaft and the housing. Makes lining up the key easier that way too.

[@Michaelsbackyardmarina]

Yessir it is. My later videos do include this method

[@Artoconnell]

the ONLY professional way of doing it. well done sir.

[@Redbeard17]

Is this rotation always in forward gear?

[@Redbeard17]

Or always in reverse?

[@WhatsCrackin904]

@@Redbeard17 push down the housing while rotating the shaft clockwise in neutral

Just picked up a 9.9 that hasn't run in 8 years. About to see if I can bring it back to life. Your videos are helping me.

[@DudefishhTV]

Picking up a 9.9 next week that’s been sitting for 5-6 years. How did you do getting yours running? I see it was like 5 months ago you commented this.

[@MrHanowski]

Good video, thanks! A key missed point is that the bolt securing the shift linkage must be REMOVED, not simply loosened. As you pointed out later, the shift er shaft has a tapered section that the bolt engages, so it mechanically locks the shaft in place, not just "clamps" it like I thought. As a result, I had a devil of a time trying to figure out why the lower unit assembly wouldn't just slide out.

[@johncartelli]

my 1990 6hp has a one pc shifter shaft. must be in neutral when assembling.

[@AN-kg4ei]

I just did the lower removal on a 91 9.9 and after removing the linkage screw I put a flathead between the 2 halves to allow the rod to drop out. I tried everything before this and it helped instantly. Zip ties help install the impeller easily also.

Thanks, I appreciate the help. I used to work on them years ago, but got but of practice. I have a 9.9 and a 15 it'll be good to get back at it again.

[@janddproductions9512]

Thanks my man, have a project boat I’ve been working on and I came across this motor, (long story) and I am getting ready replace the water pump as a precaution before starting for the first time. Hasn’t ran for years... thanks again!

[@GO_OutDoors]

Going to be doing my Johnson 9.9 today. Thanks for the great video.

[@Michaelsbackyardmarina]

Good luck!

[@TheFrogfeeder]

Ahhhh, so the shift rod connect is between the gear case and lower unit, I usually have 1960s motors in the 22 cc platform, and they have the rod connector in a nice easy window. I just got one of these motors but 15hp/1980, it’s very different from everything I’m used to. impeller be here tomoro, I’ll install it then I’ll go from there... it looks like it should run, with the usual fuel system TLC that any long-unused 2stroke outboard needs. Thanks for the video!

[@nonamemannameless1600]

There should definitely be moved more water flowing out after you replace the pump. It is likely that your exhaust plate grommets are restricting flow and need to be replaced. There is a easy way to check this before you pull the powerhead to see. Make a tight seal on the copper water inlet tube with a straw and a spare grommet and blow into it. If it is hard to blow, you will need to pull the powerhead and check those grommets. If it’s easy to blow, and you’re still getting low water out of the telltale, it’s likely something is blocking right before the telltale and your cooling is still fine. Always check with a temp gun when your testing.

[@FishHeadsIV]

Where do you find the water inlet tube and spare grommet? I think I'm getting good water flow but not enough "oomph" moving through the water

[@Redbeard17]

Is there not a gasket needed between the water pump housing and wear plater or between wear plate and lower unit?

[@slalomking]

Good video, sir

[@hilldwler420]

Just got my 74 9.9 running now I have to do the water pump

[@Michaelsbackyardmarina]

Go for it. Thanks for watching

[@johntaylor6654]

Like you I have a long shaft, my unit had the same grommet as yours installed [the short one] the instructions seem to indicate that grommet number three [the on with the large flared top] is required. I used the same one as you did. ?? The tell tale is pretty weak on my unit, even with the new pump.

[@jaredhubbard5214]

Awesome job man

[@Michaelsbackyardmarina]

[@robertyearian227]

[@BryanParrish-o3n]

Hi love your work, When you slid the impeller over the key your hand blocked the view ? did you lift the shaft and twist it?

[@FishHeadsIV]

I'm trying to dial in a Johnson 7.5hp. I have it on a 9.4 bass tender and it feels like it runs and revs fine but it doesn't have the same power I've seen other people get out of Thier boats. I also get sludge coming out of the exhaust over the prop.

@@Michaelsbackyardmarina sure did. Knocked out a water pump replacement in about 30 minutes flat on a 1982 Evinrude long shaft.

[@mikebadilla6970]

[@christophercarter3685]

easiest way is to put the impeller on the shaft then install the pump housing grab the shaft and turn it clock wise as you push down on the pump housing make sure you grease the impeller and housing and it will seat itself nicely no fighting the impeller to get it in

[@Michaelsbackyardmarina]

I learned that shortly after this video

[@robertmurphy6621]

What did you use to get the bolts out of the spacer unit. I tried a flex extension but won’t budge it and won’t fit in the space around the bolt. I can get at the lower housing bolts but can’t find any thing to remove the spacer bolts. Frustrating. I know I can replace the water pump if I can get the bolts our. Please suggest something. Thanks

[@DudefishhTV]

Super helpful videos on the 9.9s. I had zero confidence to work on it myself until now. Picking up my first aluminum boat with a 9.9 next week. Looking forward to breaking it down and checking all this stuff out. The guy I’m buying it from said it has been sitting for the last 5-6 years but the fuel had been drained prior to that. Any advice on the first few things I should be concerned with first? I’m assuming this motor is going to need some love to get running again but he said it ran great so 🤷‍♂️.

[@Michaelsbackyardmarina]

After sitting that long I would go after the water pump and replace the impeller in it. If he ran it dry before storage, If it were me I would hook the water up and filler up with some two stroke mix fuel and try to start it and see how well it runs. I would pull the plug and check for spart first but then give it a yank.

Good morning.! Thanks for your movies ..! Very useful. I have some advice to ask you ... My 9.9 johnson It has one cylinder that heats up more than the other. The coldest cylinder is the one on the carburetor side. Could the left cylinder water circuit be clogged? Thanks if you can answer me.

[@Michaelsbackyardmarina]

sounds like it could be. Or you have a thermostat that is not working properly.

[@johnnylawrence]

Great video thank you. I have a 1992 9.9hp evinrude and after taking it out of storage over the winter, the throttle will not turn in neutral. Its like its siezed. It will engage when shifted in drive but once back in neutral its siezed and the idle dies. Any suggestions?

Where does the smaller o ring go? I’m guessing the shaft? At the very top where the groove is?

[@pg-mtl8815]

Hi Michael! What kind of grease do you recommend? Is lithium grease ok? My kit didn"t come with any... Someone told me to use dish soap. Also, my kit comes with a small o ring. Where would it go? Can I remove the foot by loosening the the 6 bolts from spacer part and remove the 6 from the bottom afterwards?

[@Michaelsbackyardmarina]

I use marine grade grease and you have to remove it at the top of the spacer first to get to the shift linkage

trying to put together a 1990 sailmaster 6hp. not quite the same as the shift shaft does not split its one pc from the engine down into the prop gear box. my problem is the lower unit will not go all the way up to meet the upper housing. another words i have the extension housing together with the lower unit, the copper tube goes into the pump but either the drive shaft or the shift shaft is hanging up on something preventing it from coming together by about 1/2 to 5/8ths of an inch..not sure what to do at this point..have you ever had that experience? anyone?

[@Michaelsbackyardmarina]

I have not. Not familiar with the sailmaster. Maybe someone watching might have an answer for you.

[@johncartelli]

@@Michaelsbackyardmarina well as luck would have it turns out you dont leave the shift in forward. As i was applying pressure i put it into neutral and it slipped into place. I picked this engine up for $150.very clean was told the starter rope broke. turns out the bottom of the rope drum had severed and the nylon bushing (unavailable)it sits in had worn out. i made a new bushing found a drum on ebay. ($25) bought a new pull start and it works like a charm. for reliability sake i also rebuilt carb, replaced hoses to carb., rebuilt fuel pump and lastly checked the water pump (only to find its housing had melted including the impeller key. your videos gave me the confidence to take care of everything and its now ready for spring.thanks for a very informative video site, keep up the good work.
