MERCURY 150 EFI WATER IMPELLER CHANGE | HOW TO

[@ReelLifeFisherman]

I would like to add .. in saltwater I would not recommend putting loctite on the impeller housing bolts .. use perfect seal or a light coat of anti-seize .. the factory uses loctite there I wouldn’t personally..

[@ajfromcjbasements6574]

I also work for tracker... Yeah locktite there is a pain in the ass

[@ajfromcjbasements6574]

I put it in forward and turn the prop shaft when I'm putting it back on I've seen a newb force one in... You already know how much of a headache that becomes 😂

[@philwyatt2160]

Another great informative video. I got lucky and it slid straight back in. I had left it in gear. Cheers mate!

Great video and thank you! Saved me a lot of hassle seeing how you engaged the shift shaft while being in neutral…not sure I would’ve figured it out otherwise.

[@chuckbuddystrainer8632]

Are you kidding me?That is the clearest most precise how to video I have ever seen. Not. To mention your wife is a fantastic Camera lady. I can't wait to change my impeller now. I only hope I can be that calm through the whole thing

[@glenwagner943]

That truly was the best video I’ve seen on impeller changing. Hopefully you are a teacher because you have great skills on getting the point across.

[@ReelLifeFisherman]

Thanks you very much! I appreciate that! I do train guys at the shop.. but maybe one day when I’m too old to work in the shop I can teach ! lol I just tell it like I would like to learn it myself for the first time..thanks for watching the video and the comment..

Your a legend my friend! Thanks from Australia! I completed the 100h service from other video and it worked great. They charge $650 for that service here. I wasn't happy after my last service with local Mercury dealer here. They charged me for some parts and didn't even replace them. I service electronics and use a trick to see if they replaced the parts. I put a small mark with sharpie on the part then see if the mark is still there after I pick it up. Got charged for some filters and he swore it was replaced yet my sharpie mark was there where I put it. I was NOT happy. Thanks to your videos I now know the parts were replaced.

Great explanation of steps and logical reasons why they are taken

[@DrJohn493]

Good, thorough demonstration! But after watching this vid, I'm glad I decided to let the boat shop replace the impeller on my Merc 115. Money well spent for someone that is not familiar with outboard maintenance and repairs. Replacing the impeller on our sailboat engine was way easier but that was years ago when I didn't mind doing mechanicin'. And had to do mechanicin' while underway.

[@nomad7412]

[@j.l.daltoin2238]

when I put the impeller in I put it on the shaft and watch the keyway go in and rock impeller back and forth to be sure it's in position then slide the water pump top housing on slowly turning the drive shaft clockwise only as I put the pressure on the w/p top housing as it slowly goes down into position with a little pressure on it going down with my hand the reason I do it this way is if I put the w/p impeller in the housing first and push it down I've had the key fall out the way you do it even with the grease trick but if I put impeller on first and I can see the key go in and line up so I feel a lot better that I've got this part right but like you I have better luck doing the going back in the neutral position good video sir I guess different strokes for different folks lol

[@hooks4nooks]

You do great videos. I'd love to see you do a walk through on switching a Mercury 115 pump to Prop with bay kit, extensions for shaft, shifter, water pump, longer studs.... You helped me in comments but to actually watch you do one would be awesome. So much to it. And then switching back to pump too. 👍 Take care.

[@DialedIn57]

Your videos and instructions are awesome. Great job. You can tell this is not your first rodeo! Thanks

[@gvanhove]

I just took mine apart and it shows the impeller fins twisting the oposite direction of how you inserted the new. Actually mine looks identical to your replaced impeller and you have 4 fins that turn clockwise and two badly worn. If you think about what you mention in twisting the impeller clockwise to insert it into the housing and the housing is upside down in your hand then you'd most likely want to twist it counter-clockwise while inserting. Either way it should not hurt anything though, but it is possible.

[@jimk4267]

you are correct he installed with a backward twist

[@corvette7444]

Best video i have seen on removal of water pump impeller.Was confused on the you have to bump it that to me means you have to kit the key and bump the engine other than that good job.

[@ReelLifeFisherman]

[@ABQGeo]

Good job. Best video by far on this topic. Like you, I have found that the question of doing this in gear or neutral meets with about equal success. The Mercury manual says In Gear. I've used a large properly fitting socket with breaker bar to slightly rotate the flywheel to get the drive shaft to align. Getting the weight of the propeller off of there is a must for this old man :-) Thanks much.

[@ReelLifeFisherman]

Thanks I appreciate it! Glad you like the video! Yeah I just seem to have better luck doing them in neutral most times .. but if I’m alone I don’t have a choice but to do it in gear like the manual will tell you.. tanks again for watching and commenting!

At first I thought this was going to be an easier job than the impeller on my Honda 40. After seeing the struggles with the shift shaft I can see this engine is more difficult. Good video though.

[@fishnbaja1]

Well, I'm personally glad you didn't get the lower part right the first time. Otherwise, I don't think I could have put it back together myself. After a few curse words, and a pair of pliers to turn the shaft just right, I was able to finish the project. That, however, did not fix my problem, which was that water does not come out the tell tale valve. I have the same engine you have. Great video, either way.

[@timrowlett5451]

Great video. When you say "bump start" do you mean use the key? Wont the motor start? I'm doing mine this weekend

[@ReelLifeFisherman]

Yes use the key or a push button start jumper if you have one .. I've never had a problem using the key method but to be on the safe side unplug the crank position sensor on top of the engine at the flywheel. There is a two wire connector there red and white wires. The engine will turn over but will not start.. the risk you run not unplugging it like in the video is if the lower shifts into forward and the driveshaft engages in the engine, it can try to turn in your hands and hit you if the lower is not on the studs when it engages. This has never happened to me in my 10 years of experience but it is a possibility.. so to be on the safe side unplug the crank sensor and just have someone use the key bump it to start then back off as soon as it turns .. do this until it lines up. Let me know if you have any questions.. thanks for watching

Hey man thank you for the video! You’re a life saver! I just swapped on the lower unit and after starting the motor I don’t have a good stream of water!? Any idea how long it takes before you get a good stream of water? I got muffs on it and ran it for like 30 seconds- minute and didn’t get a good stream

[@lindsayfraser4791]

A great video. Many thanks for taking the time to do it. 2 questions. Being from the lock up capital of the world. Melb Aust we run in salt water. Is it best to use the muffs on the bottom of the foot or use the water flush on the side of the motor. Also getting the water tube on again would putting a smear of rubber grease be ok??

[@ReelLifeFisherman]

Thanks I’m glad you liked the video! So I will always run the motor on the muffs after the salt unless I forgot them at home! lol the flush on the side works great for reverse flushing.. it is not supposed to run the motor on that.. it’s good to use if you ran through sand or mud.. or if you don’t have the muffs or can’t use them like if you keep it at a slip .. and absolutely a dab of grease is a good idea .. I do it every time on the water pick up tube coupler.. thanks for watching and commenting! Let me know if you have any questions..

[@charlierahner2141]

Thanks! This convinced me to have my Mercury 50hp done by a mechanic - unless I see something drastically different when you do that video. I may attempt to do the impeller myself on my Mercury 6hp kicker though. One question - if your kicker motor had been trimmed all the way down, would that have not solved the issue of having it's propeller in your back? Or am I missing something?

[@rayray2563]

Question? The round white plastic piece that covers the upper drive shaft seals, which has that metal ring around it! Can that be taking off and be inspected inside and cleaned? And can I reuse the plastic piece and metal ring? I ride mine in salt water and want to make sure I don’t have salt corrosion under it. And to have a peace of mind. At around 10:56 on the video you can see the part I’m talking about. It has red letters on it. Thanks your videos are awesome!

You put the impellar in backwards , the first time you put your boat in gear the impellar has to go in the other direction , which can damage it .

Exactly my thought....should be twisted in counter-clockwise (except for counter-rotating motors).

look at the impeller at mark 9:08 and then look at it at 13:14 the impeller blades are opposite. Which way should they be for a single engine Merc?

[@ReelLifeFisherman]

They should be pointed to the right when looking at it upside down.. I might have put it in backwards in this video I have a bad habit of doing that sometimes but they will typically flip the correct way once you fire up the motor.. thanks for watching

[@ronsilco7293]

I have the same motor. It hasn’t ran since I had it winterized in the fall.. I put the muffs on it but I didn’t get any water out of the telltale.Maybe ran it for 3-4 minutes . talked to the shop that winterized the boat and they indicated that if there was an issue with the impeller, they would have let us know in the fall. Could I “push” water through the clean out by the motor up and down switch on the left hand side? Or maybe gently insert a short piece of weed eater line in the telltale? Never having put muffs on before, I’m not even sure I had them on correctly. I did have some water coming out of the prop. Thanks!

Great video. Instead of bumping the motor to get the two shafts aligned why couldn't you just rotate the lower unit drive shaft clock wise just a bit? This is what i have done on my merc 50hp 2stroke, 50 hp 4s honda and 15 horse johnson. Anyone have a thought on this?

[@jimk4267]

that's why you put it in forward before removing...so you turn the prop to align

[@hardiebotha5476]

Is it necessary to drain the gear oil prior to changing the impeller? I have heard that it is required on some other Mercury engines (to prevent spilling a quart of the oil) when removing the lower unit, but you make no mention of this. I am hoping that is not necessary with this engine.

[@SCDeerAddict]

Not necessary

[@bertperry9046]

when should you change the internal anodes

[@abarber971]

Question… is it ok to put a little grease on the surface where the impeller meets the housing? I noticed when you were trying to line up the key way that it gave a little resistance, if the shaft moves the spines are going to fight you on reinstallation.

[@hooks4nooks]

Great video. I'm putting a lower unit and bay kit on my 115 merc today after taking off the pump. The linkage is done in the tiller but I had questions on the extensions on the shaft and shifter. Do I just grease the extensions together? A guy on KZbin said to super glue shaft extension to shaft so it doesn't stay up there when you put the pump back on. That doesn't seem right. But have motor in neutral when doing all this and just grease the extensions on when stuffing it all up there like you did in this video? Much appreciated. G

So the only bay kits I have installed all came from mercury had the extension for the lower unit itself with the long studs and came with a new lower unit with the longer drive shaft and shift shaft then a extension for the water tube that sits in a notch in the lower unit extension. I add a dab of grease in each point for the water tube with O-ring and grease on the drive shaft splines and shift shaft splines .. Hopefully that helps and makes sense. Let me know if you have any questions or I didn’t understand exactly what you were asking. Thanks for watching!

Thanks man, yes, that's exactly what I got from Stevens Marine. Lower unit, with bay kit and longer extensions for shaft and shifter, water pump extension and the longer studs. Sounds like the same. So it seemed to all go together well. Only thing, when it was all together before tightening down the lower, it had maybe a 1/4-1/2 inch gap but snugged up once the bolts were put on. Do you find that normal for everything to jive together the first time with that bay kit? So once it was all put together, it shifts, pees, and seems to be functional. That shaft extension wouldn't fit up in the housing and I had to take the cowling off in order to put it above the mid section on top of the shaft? I'm going to check the oil in lower and then run it. Anything in particular I should look for that might not be right? If it pees, shifts and runs fine I should be good huh? I think the next time I'll definitely take it to the shop. Thanks for your time. Great videos.
