I appreciate this video a lot as it helped me change the impeller on my early 90s mercury 20hp outboard.
Always satisfying when people take the time to comments and say that they liked the video.
I appreciate your comment very much.
Thanks for watching, best regards.
Thanks, helped me change my Merc 25 impeller. Glad I did. The old one had dry rot cracks on every blade, some over half way through the blade.
Glad that it helped you change it yourself.
Thanks for taking the time to comment,i appreciate it.
Thanks for watching,regards.
The water tube should go into the powerhead first, then put it in the lower unit grommet . That way you know its hooked up right
Thank you for the video! I have a 1994 25hp and I am about to do the impeller on mine. I have been watched many videos but yours looks to be the most helpful!
Also thanks for doing it in english, I don't know french!
Edward Wade Thanks for your comment, I appreciate it very much,i am happy if it helped you out.Have fun with your project.Happy fishing and best regards .
I have a 1998 25EL and looked at many vids and I think you are right this is the best so far.
I like the suggestion for using soap as a lubricant for the impeller seating, better than silicone on the impeller probably.
Thanks for taking the time to comment,i appreciate it a lot.
Hope this video will help you out.
Thanks for watching,best regards.
Also when you put the top housing back on the shaft make sure it is lined evenly spaced in the housings center hole so it won't rub on the shaft and cause shaft scaring.
Thanks for the heads up on that one.Regards
The washers only come with the repair kit that I know of. You can find it on Amazon 15-25 hp Repair kit # 47-85089T 4. Price $31.78
Ok ,i will check that,when i checked on mercury catalog parts it was N/A and a lot of site saying the same thing.Maybe they are just selling it as a kit now .Regards.
Vidéo trés utile malgré certains raccourcis pris pas son auteur et notés par divers commentateurs. Personneĺlement, j'ajouterais de graisser les rainures (pas le dessus) de l'arbre de transmission pour faciliter sa réinserion dans la tête du moteur et éviter qu'il saisisse dans les années à venir. Finalement, le thermostat ne contrôle uniquement que la circulation d'eau dans la tête du moteur et non pas l'écoulement de l'eau par l'indicateur (pissotière latérale). Bravo ! Les boulons du pied sont serrés à 54 Nm.
Vous avez raison,j'ai fais ce video pour aider ceux qui ne savent pas cpmment...Je ne suis aucunement mecanicien.
Merci pour le comementaire et pour avoir regarde la video.Salutations.
Thxs exactly what I needed to see for my 93 merc 20hp impeller change my impeller is working great I was concerned that the slow and steady telltale stream meant i had a bad impeller but now that I've seen yours running it does exactly the samething as mine yours does a slow dribble then a steady stream then slow then steady so I guess I'm good to go. Must be how merc builds them
They have a thermostat,so when idling they will do this.
@@obscur156 Should it be a steady stream when you are going full throttle? my motor does excatly what Joey's motor does but when going full speed.
@@emilpersson6812 These motors have thermostat so they give steady stream when they reach a certain temperature.
So yes,when going full throttle you get a steady stream,when idling you will see a stream dripping on and off.
@@obscur156 oh ok, so we might have a problem when its not giving us a steady stream when going full throttle. it does the on/off for us when going full throttle(when it goes "on" it is a really good stream) 🤔
@@emilpersson6812 Depends on water temp,if the water is very cold, it will not go full stream.
If you get full stream in cycle,that means your thermostat do it's job...
You're the MAN!
I am happy that it helped you out.
Thanks for watching,regards

Hi. I just replaced my water pump today 5/16/22 but still don’t have water coming out. Do you know what el could be the problem also I check my thermostat. ? Looks like the shafts is not spinning
It will start peeing only when hot ,you should see drips of water and steady flow when motor reaches a certain temp.
With the termostat,peeing will go on and off.
torque spec for the bolts is 60 inch pounds or 5 ft pounds.
Thanks for the heads up nelson !
Thanks for watching,regards.
There is suppose to be a plastic washer under and on top of impeller.
Yes but if you want to buy one you will find out that the part is N/A. No more available...
It is in complete kit
Thank you very much :)
You are very welcome my friend,Thanks for your comment and thanks for watching.Regards.
Does anyone know if the four black grommets in the kit go in between the pump plates or straight through both plates from the top between the washer and the top plate?
Good point ! Frenchy didn’t take the plate off so it would have been hard to tell. The grommets appear to be under the plate below the impeller. I believe it’s called a wear plate. I am getting ready to do the impeller complete kit on my 1999 20 hp Mercury I will post a removal and replacement video if I can. No offense but this job was shade tree at best mechanic work. With missing parts he may have issues in the future. My engine btw has never had an impeller change but perhaps after 21 years of service a new one is needed. The engine shows no sign of having water pumping issues but at this age I would hate to be 30-40 minutes out and have it fail.
@@rogern5368 I did my 18xd after sitting 20+ years. We called it the one jerk Merc before it sat around. The original impeller looked new except it had a crack in one spline from dry rot. Haven't put it back together yet. I'm waiting for the new decals. Good luck with yours. And when you tighten it up don't use too much torque or the plastic bushings will twist and squeeze out.
Very nice,like
One of the six has a shape that makes supose it hasn t bended right ....?

Thanks, just curious is the water conform the lower unit normal? I have a mercury 20hp 2008 model, seems to run fantastic,pumps water great but there is water coming from the lower area. Just wondering if this is correct or should I be worried?
Would be better to see it but there is water coming out of the lower unit at least at one or two spots.I guess its normal.
Thanks
There are weep holes in most lowers to keep water from pooling up and possibly freezing in places it can collect.
It looks like you have water coming out where the lower unit meets the exhaust housing. Is that normal or no?. My 94 Merc 25 has water coming from there also. Not sure if it is normal or a bad seal somewhere.
I am pretty sure that it is normal
I was checking out several other videos tonight and they all had water coming out in the same area. So that has to be normal and I was needlessly worried about it.
yep,thanks for watching. Regards
Would anyone have a part number for the imepeller or the kit

Good luck,best regards
what is the size of the shaft
Approx 9/16 inch.Just mesure the hole in a spare impeller.
Poderia apenas ter lluminacao suficiente
User more light
Agreed,I will do my best next time.
Thanks for watching,best regards.
