Heh, I picked up another little trick for my self watching your video. I have three outboards. a 4 hp Johnson 2 stroke, a 9.9 fuel injected Suzuki, and a 9.8 Tohatsu. I just a beginner with repairs on outboards. But recently I replaced the impeller and housing for the water pump on the 2 stroke. When I went to put the drive shaft and lower unit back together I had some trouble getting the splines on the upper part of the drive shaft to mate with the gear box on the lower end of the engine. Now that I see what you do I can’t wait to try this trick you introduced me to. “Put the lower unit into reverse before installing...”. That way you can manipulate the splines to mate. That was very cool. Thanks again...

Outside of a few out-of-view camera scenes, outstanding. Clear, concise, and not wasting any time. Thank you.

Excellent video. Covered all the points needed - saved me having to bring it to the shop, and I got my motor running again.

One of the best impeller change videos I have seen in a long time.

Wow! As others have said, you have a gift for teaching or at least instructional videos! Great job, very detailed. I think my 9 year old son could follow this and change an impeller. Lol. thanks for uploading

Great tutorial! You are direct and speak clearly. Fantastic!

Thank you. I learned a lot today. This is a very vital pc of the boat transmission.

You should make a video teaching others how to make instructional videos! Thank you for the short, sweet and to the point instructional! Keep up the good work!

Very well done i loved it, no going sideways and mixing things up Cheers.

Nicely done. A great help for me. Thank you.

Thanks man, great instructional video!

Excellent tutorial, thank you!

Extremely helpful; thanks for taking the time.

Nicely done wink. thank you. Tackling this today.

Great instructional video! I thank you.

Worked perfect for me. Thank You so much

Great video. Only thing is you didn't mention if it matters which way you turn the drive shaft when reassembling the impeller into the water pump housing.

Great and simple. Nicely done

You made my day bro!!! Very clear an clever explained - Go on - BR from Germany

Wow, fantastic job on this video!

Thank you! Great video!

I learned a lot thank you👍

Thanks. First time try. Will see how she goes. Would not have attempted without a clear lesson.

By far the best instructional video I've ever watched I never leave a comment I honestly think this is my first one but good job buddy

Fantastic video, very well done, thanks!!

Could you show what direction the water pump fins are to go. Clockwise or counter clockwise? Very good video !

great video ,your instructions are clear to the point ,cautionary with limits and the flow was easy. thanks well done

Thank you too much. I've got same model outboard and i was thinking about replacing impeller how can i do this job. Your video explains everything very well. Thanks a lot and hi from Turkiye...

Very helpful! I am going to tackle mine this week, although mine is a long shaft .

nicely done job this video, thanks

great video. it helped a lot

Hi thank you for your instructive videos. I have a mercury 9.9 4t . I realized that there are numbers 1-2-3-4 on each bolt that connect the lower leg to the upper unit. I suppose that these numbers define the sequence that I should follow in operating the bolts. But I could not find any answer to the question " should I follow the sequence 1-2-3-4 in loosening or tightening the bolts ? " I appreciate your advise. Thanks

good video, thanks a lot

Thanks for taking the time to make this. Very clear and easy to follow. You forgot step 1- Scrape off barnacles and oysters so I can locate the lower unit. Hopefully a family of crabs aren't living in the impeller housing!

Can a 2016 9.9 hp mercury 4 stroke be converted to a 15 hp. ,by replcing or rejetting the carburator?

great vid thanks

Great video!

Picked the part up today and installed. Thanks.........wink

Thanks you. For one 15 gamefisher change the water pump is the same??? Thanks.

GREAT AND THANKS!

It would be GREAT to know what people are working ON!!

You did a great job but I have to point out a couple of important errors. It is Very Important to rotate the drive shaft in the "correct direction" while replacing on the housing @ 6:27 or you will destroy your new impeller. Also, Do Not use petroleum-based grease on Rubber Parts @ 7:08 as it will break down rubber over time - use Silicone Grease on Rubber parts. Small details - what Make/Year/Hp of outboard? How did you get to the shift linkage?

Great video! I'm going to tackle this job. What gear should the motor be in before dropping the lower unit?

great video on changing waterpump I own 1999 Mercury 15hp manual start. Quite on me out in ocean - thank heavens for fellow boater who towed me in. Tried rope starting when floating around waiting for the tow but the engine would not turn over I followed your video but the water pump is fine. When I removed rope start housing I am able to rotate the fly wheel nut with a wrench but only goes 3/4 of a complete circle at which point it binds. Your thoughts? Sam

Great video. One question I have is what direction did you rotate the drive shaft when you worked the pump into the housing. Does it matter?

When you install the impeller housing is it counter clock to get the impeller to set in??

thank you

How long should it idle in testing before water is discharged? Does it hsve a thermostat?

Which way do you rotate to drive shaft when you're putting the impeller in the cup

My doesn't want to pee anything. Suggestions? I noticed before I was to changing oil on my Honda 20hp. I warmed up my oil by running it in water but no water peeped out. Clogged maybe?

I’ve got a 3.5 Mercury four stroke with Neutral and Forward only. I replaced my impeller and lined everything up as shown in the video but my motor will not shift into forward for some reason? Any ideas?

He make it look seamless

How would I clean out the broken impeller parts out?

You forgot to mention to turn the drive shaft clockwise. Also Marine grease on the driveshaft splines as well as the impeller and the water pipe connector going to the motor make everything go smoothly.

Is that a mercury 8hp? I’m in need of water pump gaskets for a 2006 but can’t find the part numbers

When putting the impeller in which way do you rotate the drive shaft ?

Fun fact..... This "Mercury" motor is actually a Tohatsu. Made in Japan. They are bullet proof, and do a great job of protecting themselves from their owners with over rev and low oil protection. Happy boating!

how do you remove the lower half of the water pump? Does the drive shaft have to be removed first?

Thanks for the video. Do mercury 9.9s have an oil filter?? I read something about that in my manual but cannot find it on my motor..

I am not having a question on this exactly but...I started my engine a couple days after using her for several hours and I just made sure she started because she died in the water from swells cutting off power. Anyway, I put in forward and reverse only for a moment and shut her off. Now she is not starting at all. Not even idle for a second just barely after letting sit over night did I get a little smoke come out 1st pull and a attemp to start like the sound the 3rd pull now nothing is happening again. Any tips?

Good work! Did same repair today…all good! Rebuild kit 179 cad @ dealer or 42 cad Amazon. Hmm.

Well done.

Does it matter which way you turn the drive shaft when installing the water pump housing over the impeller?

Would u know if after replacing all those parts it's still not pumping water in? What else could it be

So the impellers find their own way when it spins I'm imagining.....I thought they had to be put in the direction of the clock or wise spin of the drive rod. so the shifting rod adjustment is critical. explanation

rotate shaft which direction? could not see your hands

Does it matter the orientation of the impeller fins when replacing?

I have a yamaha f15 2012 and it is overheating only at idle. It pees fine with new impeller new thermostat and anodes. What might be wrong???

My impeller is so tight in the cup it's ridiculous. Need to know which way the fins are supposed to go?

Well done sir

What happens if my prop only turns one way and when I turn it, there appears to be a clicking noise. I obviously did something wrong, but what causes the clicking noise. Thx in advance!

I have a question about the water tube coming up from the pump, if I have water coming out the tell tale, tells me the pump is working, but the issue I’m having is water coming from between the upper and lower parts of the body ,coming out near the area in the vicinity of the shift rod, so do I have a thermostat issue and water is backing up , maybe coming out of the water supply tube or is the tube broken?. Unit worked well prior to last season and I didn’t change anything yet. Thanks

This is our key! *Drops to oblivion*

One thing I haven’t been able to figure out is I have had to replace my 3 times.I have a 2015 Honda 9.9.when I take it apart it’s looks like the housing got melted a little.I never run it dry and the prongs are dry and broke off,I have never had the problem with any other motors I have owned.

NOTICE : When removing the water pump housing, remove the screws completely, then pull it up. If the impeller is a little tight and is pulled out while the screws are present, the gasket is attached to the screw threads, and the impeller blades that are opened are caught and torn off.

may I ask what kind of motor this is?

And when reinstalling lower unit apply grease to dive shaft and all the bolts you will never have a problem removing them next time

Is this jon from Fly8MA?

Are you the same guy who makes the aviation videos ?

Thanks for the video. Your shop floor is very messy. You (or whoever) should keep tools picked up and the floor clean. Question though. . . How do you get those impeller pieces out of the lower unit ?

It takes much longer than 15 minutes! He just realized he needed to remove the nut completely!

You did not say what direction to rotate the drive shaft

You just cost outboard mechanics some real $$$

Just use InpliX instructions. you will make it. its so easy

You didn't say which way to torn the shaft !

Dern trying to find water pump video on 52 kh7 is like a secret James bond secret... Anybody know?..

You didn't show how to take apart the motor to get at the shift rod. My motor you cannot even see the shift rod it is covered with steel.

I cannot get the drive shaft seated and the lower unit reinstalled to save my life. I'm ready to throw it in the trash!

Thumbs down for all the commercials

You forgot to lube the impellor or clean the water input tube. I’d never let you work my engine.

Terrible example you did t mention lubricating it and you didnt mention the direction the impeller has to go in please don't post u tube videos that are not complete.

thank you

You just cost outboard mechanics some real $$$
