Thanks for sharing and i love no music and excessive talking. Very helpful

Like so many others who have reported, I too had problems with assembly of the lower unit to the upper. R&R impeller, etc, took an hour. After that it took 3 hours to attempt to put the two together and another two hours the next day. I can't say that I learned much as to why I had so many problems trying to get the two to properly match. I will mention a few things I discovered in the hope that someone else might benefit. I'm working with a 6 HP Mercury 4-stroke made in 2001. 1. There's a cam on top of the flywheel that won't allow the pull starter rope to operate unless it's in neutral. As I found that the lower unit must be in reverse to assemble, I put a pencil, or other item under the arm that the cam pushes on falsely raising it to neutral position. This allows you to pull the starter rope in whatever gear position. Pulling the spark plug will make pulling easier. 2. When the lower unit is on the bench, it's hard to tell what gear it is in. I drilled a 1/4th inch hole in a block of wood and used that to push the shift rod downward by inserting the upper end of the rod into the hole and pushing. Otherwise it's very hard to hold onto a greased rod and expect to exert any pressure. Also, measuring to top of the rod to the base at the bottom I found 14 inches at the reverse position; 14 ½" when in neutral. That seems about the only way to be sure what gear it's in. 3. After hours working on this and making very little progress at one point it got within about 5/16th inch to complete assembly. At this position I was able to get threads on the assembly bolts. I cranked her down happy for its completing. That elated smile quickly turned downward when I discovered that I couldn't turn the engine over nor shift gears at the shifter lever. Disassembled again, and try again. 4. After my step 3, I think I may have bent the shift rod. This required some straightening. I studied the video very slowly to ascertain the rod position when assembled. Coming from the base the rod goes straight, then slightly bends, and then straightens out again running parallel to the drive shaft. That rod can turn. The orientation of the upper bent portion of the shifting rod is closest to the drive shaft. Rotating it 180 degrees and it would be further away from the drive shaft. Keep the upper portion of that rod in a position closest to the drive shaft for assembly. 5. The stars were aligned just right and after about five hours over two days fighting this assembly, both halves slipped into position and quickly were bolted together. 6. Conclusion (and this is only a probability) is: set gear shift lever in reverse; push shift rod into reverse until it is 14 inches top to base; orient shift rod such that the upper portion is closest to the drive shaft and hope for the best!

This is how instructional videos should be made... No useless blabbering (like lots of videos here on youtube) and straight to the point + it can be understood by everyone! Thumbs UP !

Perfect video that helped me replace the impeller during this year's holiday in Croatia. Thank you very much!!!

Thank you very much for the very clear and and concise way you presented the information. It was extremelly helpful

Thank you for posting! I have to do this to the same exact motor and it was very helpful to watch this before starting the job. :)

Worth knowing: when I took the impeller housing off and inspected the impeller, it looked immaculate - no cracks, rubber in good overall condition with no obvious wear and tear apart from the usual 'bent' fins. I cleaned everything up and by the time I went to put the old impeller back in, the fins had straightened-up again - I was positive the impeller was perfectly fine and my problem lay elsewhere. I assembled the unit and tried it again; still no 'thrust' of water but a feeble 'drip and dribble' - like an 80-year old with a prostate problem (sorry guys) I poked into the tell-tale with a bit of wire; 'maybe there's some river sand blocked in there?' The wire sailed-in with no obstruction. 'Hell, it must be the thermo, or something equally horrific?'.. I'd done enough for the day and decided I'd install the brand-new impeller next day - "I don't think it's the impeller. I'm absolutely sure the existing one is working fine".. Next day I dismantled the lower unit (in a jiffy, cos now I knew what to do) and installed the new impeller that I'd received in the post a couple days earlier. Would the brand-new impeller make a difference? I fire-up the outboard (Tohatsu 3.5hp) and the thrust of water spewing from the tell-tale, like a fireman's hose, told its own story - I was delighted! Having confirmed what the fault was, I took the new impeller out again and installed *all* of the new parts that came with the Tohatsu kit - the impeller, pump case liner, key, pump case gasket - and cleaned and re-greased as necessary. Moral of the story; don't assume the impeller is okay cos it 'looks okay' - it's more than likely goosed. Change it.

what a top man you are! Full respect.. Thanks very much indeed for posting this video. very much appreciated.

Great presentation with no talking. Loved it. Thanks.

Just the right amount of dialogue.

In 2020 this video was still useful, Thank you for making the video.

I just did this job and the video was helpful - Thanks! I wanted to comment on the last major step - getting the drive shaft and shift linkage back into place. This was challenging. I was only able to do this after removing the rubber grommet that the shift linkage fits through. This makes the hole much larger. After getting it bolted back together, I then put the grommet back in (a tight fit but possible). Also in this step be aware that there is a water tube that must fit into the lower end when sliding it back together.

Don't be fooled by an impeller that is still pliable. These impeller fingers should stick straight out. These are positive displacement pumps. They actually get memory after a bit of being bent in the same position. This guy did an excellent job on this video. It went to perfect until you go to put it back together!!!! There were a few comments about problems getting the lower unit back on and aligned . I also spent about an hour and got pissed. The problem is the shifter rod trying to get it to aligned with the small rubber grommet that the rod went through. I removed the rubber grommet and had no problem putting it back together. It was a pain in the A$$ pushing the grommet back on however, but a small screwdriver and a bigger one pushing down on it did the trick. If you pull your old impeller out and the fingers are bent, you know it is time to replace.

Great video! Clear and well done!

Thanks so much for this video. It made this job doable. As others have said the hard part is putting the lower unit back into the upper unit. I did two things to make that work. 1) Did exactly what you did down to the tiniest detail. Took 4 tries to realize this. 2) Took the little rubber grommet off so the shift linkage would fit easier, then replaced it. It all works great. Shifts good and runs without a problem.

Thank you for this post. Usefull!

Great video. Thank you.

I just reassembled my motor. As so many others stated, the biggest issue was getting the drive shaft back into its seat in the engine. After several failed attempts, I used a thin, straight metal rod and a flashlight to see that there is a sleeve just under the fly wheel that the shaft needs to get through. First try and by gently feeling it through as I fed the lower unit on, it clicked into place. Gentle tug on the starter cord and it fit right in. Also, I had it in what I thought was reverse, but turned out to be neutral. Adjusting was easy by using pliers to push the shift rod down after loosening the brass clamp in the side, then shifting to reverse, and tightening back down. Thanks again for the excellent video!

Ontzettend bedankt voor deze video! Ik heb vanavond me impeller vervangen!!! Ik vond het terug zetten van de staart erg lastig, maar toen ik het door kreeg was het een fluitje van een cent. De as in de "buis" icm met het versnellingsijzertje tegelijk was een hele opgave🤣👍🏼.

Thanks dude!

Thanx man for the help!

excellent video thanks

Top! Deze instructie zocht ik!

Mooie en duidelijk ook👍🏻

I tried to return the lower unit for 3 days and then it just sat down ( Tohatsu 5, 2Stroke, short shaft) . I think it takes experience in all this, but not a problem. Everything went into place, I adjusted the gearbox, water normally flows through the hole.The video helped me a lot, so thank you very much.

Best impossible!...Thanks!!!!

Excellent. Same exact procedure for my 1998 Evinrude 5 HP E5RLECS

Perfect thank you

Your video was very helpful. But why didn't you use all of the new parts in the kit? Thank you

leuke video

Sure seams like there is a lot of play in the new impeller at the drive shaft. I know that they make like two different size shafts. On different years. So it’s just a good idea to make sure you have the correct impeller. I’m going to change the lmpeller in my 9.9 mercury this year so I thank you for the good info

Great video, thanks! Funny thing, as I watched you work that shaft into place, I thought to myself, I'll bet that isn't easy. Then I read the comments. LOL

Nice video

Great video, love the no commentary. I feel a bit more confident after watching this, but you made it look way too smooth and easy. You probably did this a few times. Wish me luck. 😳

Cool... Kieth Urban just showed me how to change my impeller....

Hallo! Thanks for the instruction video. whats the white stuff you put on the impeller? grease? what kind?

I must mention one more thing about the shift rod. The upper, top end of the rod, once assembled, comes out of the upper end of the cowling. When in reverse that shaft pushes a plate that locks the motor tilt. Part of the difficulty is likely getting those holes aligned. Perhaps playing with the shaft through the side connector hole will help with alignment.

I had a horrible time getting the lower unit back on. In my case I had to loosen the bolt/clamp bracket on the gear shift rod and connect to the upper portion of the shift rod once the drive shaft was fully engaged ( clamped the upper and lower shift rods thru the hole in the casing) . Then the bolt stripped the threads in the brass clamp that connects the upper and lower shift rods. jury rigged this with new ss steel bolts grommet etc. and now works like a charm.

Make sure the shifter shaft goes back through its hole! Its not obvious to a first-timer, but when reassembling make sure the lower units shifter shaft goes back through the small hole that pokes through the bow side of the casing. I spent a couple of hours trying to put the lower unit back on before I realized that. I felt like a prime idiot when I did. FYI the Mercury, Nissan, and Tohatsu 4/5/6 are identical with only the labeling on the cowling being different.

un vrai pro

top filmpje. wel wordt er erg veel vet verspilt op delen die dat helemaal niet nodig hebben.

If that white grease is lithium marine grease, which is what it looks like, I wouldn’t be using it on the rubber impeller. Just in case anyone is watching this video as an instructional thing. If you must grease it, use a silicone based grease. Most outboard manufactures recommend no grease though.

Awesome video! I have same 2015 Mercury 6hp 4 stroke Its stuck in forward gear. Do you by any chance have a video about this?

Some narration would be great. What are you doing to the shift rod in the last 2 minutes? My Merc 6hp breaks free and revs under load. I was told it might be the adjustment on the shift rod...and that it may not be fully engaging when I shift into forward. What is the procedure for adjusting this linkage? I just had it apart and did an impeller change and seal replacement. I suspect I have the shift rod incorrectly adjusted.

Great video! I just followed the same steps but now I’m having an issue with the linkage I think. Motor won’t go in neutral, every time I pull start the prop spins.

Het aan elkaar vastzetten van de schakelstangetjes blijft een raadsel. Nieuwe sparepart gekocht maar zit geen schroefdraad in het ene blokje. Hoe krijg je de 2 messing deeltjes vast op elkaar? Voor de rest bedankt voor de demo.

Mercy ;-)

So you did not use any new gasket? Thank you for video.

Was that brake cleaner you sprayed it with?

very clear

Thanx. Ik heb gedaan zoals uitgelegd in de video maar ik krijg het onderste deel niet goed los. Tot zo'n 10 cm en dan stopt het. Versnelling staat in achteruit en dw schroef van het blokje dat de twee staven aan elkaar verbind is los (wat achter de ronde rubberen dop zit). Ik zal iets vergeten zijn maar weet niet goed wat. Iemand die mij een suggestie kan geven? Alvast dank.

Kan het kloppen dat de schroef draait als je de buitenboordmotor in de vrij hebt? Heeft dezelfde draairichting als in de achteruit en als ik mijn voet tegen de schroef zet stopt hij met draaien, hoort dit zo?

Ive watch your video over and over I tried keep the gear in neutral I accidentally hit it trying to put back the lower end and some how wont go all the way in to flush to secure bolt it's been difficult..

Good

How do I change the fuel tank on this motor the threads are stripped or looks corroded on the tank

so, why did you buy the repair kit? you only used the impeller. good video and helpful information. thanks.

Just spent 4 hours trying RE-install the lower unit, I had to measure the distance which help me to carefully catch the small opening into motors receiving end. For hours I kept missing it at the same distance. I finally lined it up right and went in the rest of the way.

I don’t understand, should I put the gasket on it? If not, what is the gasket(s) for?

Is it normal for a small amount of water to come out of the plug where u connect the shifting rod together?

Why does it look like you didn’t replace the gaskets? Did you?

,after loosening the three nuts the gear box wont split from the shaft movememt left and right but not down,any tips?

I have the same motor, trying to remove the engine block but after taking all 6 bolts off it doesn't move at all... is there anything else I need to remove first?

Hi! I have a question why on the video shows that in the original spare part bag with impeler are also sealings but he doesn't use them why?

What is the white jelly that you are applying?

Can't get the prop assembly back up into engine block something doesn't line up?

What kind of spray did he use to clean? And what was the white lubricant ?

zit er een thermostaat in t blok? ik heb namelijk de zelfde motor maar bij mij is het probleem dat ie te warm word (blok) en het koel water blijft net zo koel dr in als dat t er uit komt ......ik hoop dat hier antwoord op heb dankje wel

Wish he would explain the most difficult part. Does anyone know any other video that actually help you at the end. This lower unit is causing so much stress, thanks in advance

What if the rubber part comes off, but the metal ring from inside the impeller are stuck on the driveshaft? how can I get it off?

Thanks for posting. Nice video. What's the trick for sliding the shift rod through the clamp on the shift linkage? My friend and I spent three hours yesterday trying to connect the clamp through the hole in the side and couldn't get it. Also we had trouble getting the shift rod to go back through the little hole on the top of the case.

No mention/showing of the very important little pin !

After I changed the water pump impeller, there's still no water comes out. Does the impeller have right side, or both sides are ok?

Boa noite. Gostaria de saber como sacar a coroa e piaõ do diferencial do mercury 5 h p

More of such videos

Considering the age of this video i think I'm unlikely to get a reply but anyways......... I have a case in which the shift rod when in its lowest position puts the engine in neutral and not reverse, when I try to start the motor the prop is turning. I dont know how I manage to lose reverse. Have no choice now but to get all the parts together and find a mechanic to get it back together for me.

hey, I can't get the lower unit back in everything is just the way it was when I took it off. any suggestions? thanks brother.

is it the same for 2T ??

What grease is that

how do you make 6 hp out of this engine what part needs changed

Need to clean drive shaft of crud with oiled emery cloth to stop it svratching rubber sesling grommet.

How to close it ??? I removed the connecting block from the shifter rod, I insert the transmission rod in the grommet and I reinstall the block on the shifter rod, VOILA !

Jammer dat je niet goed kan zien hoe je die staart er weer terug in stopt.

good video but putting shaft and the connection to shifter were glossed over
