I noticed you’ve installed the impeller in the opposite direction compared to when it was removed. I do appreciate your video, as this helped me understand the sequence of the gaskets.

4:32 "This is gonna suck, but it's gotta be done". Sums up the entire project for me. Thanks for setting realistic expectations!

Well-done video. I suggest that at the very first part of the video, add a caption to tell folks to put the shifter in forward before removing the lower unit.

Performing this repair in the grass is brilliant, especially by yourself. Thank you!

I use dish detergent to lube the impeller to install. Slick and dissolves in water once started. Marina told me to when I bought the impeller, worked slick.

This is an excellent video EXCEPT you can NEVER use marine grease anywhere near the impeller itself, as it will break down the material. Inly use silicone based lube in water pump and associated areas. Mercruiser Service Bulletin.

And for the rest: when he says put it "in gear", make sure it's forward gear! The little gear shifter is a PIA to align with the part on the upper drive unit. In the end I unhooked my shifter cable and just rotated it by hand from the sterndrive to make it fit..

Boy OMC for the win on changing the impeller so much easier.

Real helpful wish the leg would just pop off like that … new too me boat

Thanks for posting! Super helpful, saved me a boat load of $$$ having a repair shop replace the impeller!

You put the impeller on put your key in and spin the prop counter clockwise. Lube with 2-4-c marine grease and bam the hosing goes right on and it's the correct way. Unlike yours which was put together backwards

Boy was that a wonderful video. I have a mess with my Chapparal right now. I’m hoping I can fix by watching your videos

"This is gonna suck". I loved this part.

Hats off to you! I’m so appreciative. I actually did it. I kinda freaked when the oil drained out. I didn’t know that would happen. No worries, I’ll watch the lower end oil change video & do it tomorrow.

Just some advice. Its easier if you put the impreller on the shaft first then slide the housing on and you can spin the shaft with one hand and push down on the housing with the other and it will just pop right in as long as you put grease or soap.

Love the vid. Straight to the point. Fast worker, good quality video and editing. Keep it up I appreciate it

awesome videos. after i watch these videos i feel you tube certified and go do the job. thanks for caring

It is so easy to move the little spline , and then have it not align with upper shifter channel , the only way to make sure , is to lay down under outdrive take a flashlight and see if they are lined up straight and propeller is locked in forward.(counter-clockwise)

Thank you. Yes I see I have a problem. The weather has already changed, I will pull it apart in the spring. Please keep supplying me with the video’s. I’m not afraid to attempt it myself.

yes very good , doesnt matter clockwise or counter, housing will correct impeller . but yes would of installed it into housing clockwise. but still very good job. two thumbs up.

Great video Teacha ! Good filming and detailed explanations in detail as to installments of gaskets , tricks,parts to save a guy some moola , when you cant afford 100 bucks a hour shop rate . Cheers man Googster. Dawson Creek B.C. Canada

The correct way to install the impeller is to place it on the shaft first along with the key, then push down the housing while you rotate the shaft. It's quick and easy, and how both the manual says to do it as well as how any professional does it. Somehow on these youtube videos you do it the hard way for no good reason.

Only thing I wish you showed more is how all the gaskets in kit go

Good video straight to the point and no nonsense. Thanks!

Thanks for the video 😀 i would never have found the bolt for the zink in the back 😂

The best way to put the impeller on is. First put all your gaskets etc on. Then put your key on, then slide the impeller down onto the key, and then put your housing on. That's the way they do it in service shops.

Your's is the best video I've seen on this. Great Job and thanks for Posting! I did our 1990 Baja 190 DSR Alpha 1 4.3L Mercruiser (looks just like your boat), prior to seeing your video, and watched this 2 days later to confirm. Your viewers will gain a lot from your explanation of dealing with the fasteners --how many, where they are, and in what order to remove. Great Job, great Vid!

Awesome descriptions and everything! Thank you for this well done video

All done buddy , little tough getting unit back on but got er ! Thanks Chris

That’s soooo difficult to install the impeller that way. By forcing it in. The proper way to install it is to put the impeller on the shaft first and simply rotate shaft clockwise while pushing upper down on it. Just a little tip for next time.

Great vid. Thanks for not dubbing in obnoxious music.

love the beer! Always gotta celebrate with a beer after she all works out!!! Thanks for the vid! Good job!

Thank you !!! I'm doing this next on mine

Do you have the link for the kit? Great video

Also you will need to put oil back in the lower unit and you fill from the bottom up

Thank you so much Sir. Very helpful video.

I have a 2000 Bayliner with alpha one drive. It looks a little different than yours. I have gear oil leaking out of the water intake. Not looking forward to pulling it apart but I downy want to ruin it. Thanks for the video.

This is good and very helpful thank you.

where are the outlet hole for water return

Again your a lifesaver! Giving this a try. Thank you

i love your channel thanks for making these videos very helpful

So I just did all n of this ibwent to put boatbin neutral and my shifter wouldn't go in reverse it finally did after a couple tuggs but now the handle spins all the way around in a full 360

Exhaust Bellows BLOWN OUT !!

Thanks man. That will be my next project.

Great video, On mine there is a line coming from the bottom to the top and from the top to the bottom. Looks like it connects to the gether. Do not connect that back together?

Surely you mean a 5/16 from the bottom, right?!

Thank you, this video helped me alot.

putting the lower unit back in is a nightmare me and my stepdad is still looking for a way to put it back in and our's is the same version as the one in the video

Thanks for the video! I replaced the impeller just fine. Started up and it still doesn’t seem to be push water out the back of the boat. Instead I see a steady stream shooting out the small hole in the front side of the lower unit. Is something clogged? Any thoughts?

My boat wont shift now. Sweet.

My pump got so hot it melted. And other issues I should be looking for while it’s apart?

Great videos. Thanks for posting them. Very helpful! “It’s gonna suck” 🤣

very well done loats of help thank s

Hey thanks for your videos good stuff made it a lot easier for me!!!!

Thanks brother, makes sense and always appreciate the help. Cheers

So I just bought a boat last summer . Mine doesn't have the top bolt on the stern drive. What is the grey piece you pulled out of it? Mine has the slot for it but that piece is missing..? Thanks for any input. Great video.

thank you for this video, nice work

I do not understand. What position should the brass shifter cable end be in on the upper unit? it seems to flop and jiggle in all directions. How do I keep in in the correct position while installing lower unit?

They guy in this video installed the impeller opposite to the way it came out. I wonder how many have seen his video and overheated their engines?

So I just did mine which was pretty easy. But there is a plastic sleeve that fits over the water tube that I forgot to put back on ugh. What is the purpose of this and is it ok to leave off?

Who else noticed that the bellow was shot when he started it the water is supposed to come out the prop with the exhaust

Thanks for the video. Just replaced the impeller following your steps (put the shifter in forward before removing the lower unit), and now with everything put back together the shifter is stuck in forward. Any idea what could be wrong? It's a Mercruiser Alpha one gen 1

That's not a 5/8 Allen key, 5/16 maybe

Question underneath the rear is a big rubber in my boat have 2 holes that’s is BAD ??????

brilliant.....VERY NICE tutorial!!!! supurb!!

Excellent video !!!!

I am getting my boat ready today i started it up water was coming out and then it stopped so i have to change mine its ben about 5 years anyway

Is there a o ring, spacer or bushing under the plastic water tube?

Good video although maybe better to use a degreaser instead of gasoline. Makes me a little nervous when folks use gas.

You are my hero

Thanks for great videos!!

Does the bottom of the key sit above the gaskets. Mine wants to sit down in the gaskets a little.

Hi was taking my off and a metal plate fell off dont know where it goes

Very helpful thank you

Is the shaft supposed to spin freely after installing impeller? Before putting it back with the upper half of the alpha one

Great video man!

do you have a link for the impeller replacement kit?

What happens if you forgot to put on that washer on top of the water impeller, ( everything else done) and its back together with oil in it :(

I just changed my impeller. Started it up and it's stuck in gear. When I try to move the throttle it tries to kill the engine. What did I do wrong? I think I may have moved the drive gear

you don’t have to drain your oil unless you have bad seals.

I have a MerCruiser 140 hp that looks like yours and I'm trying to find the impeller parts and I ordered ones that were bigger than it's supposed to be, may I ask where you got your from? Where did you buy it from or the part numbers ? Thanks and please get back to me

the last inch is a problem to reinstall any suggestion to ensure proper installation back?

Hey did you put the boat in forward gear before you did this?

Great instructional info, thanks.

Could you possibly help me identify some pieces that fell out when I was taking my lower end off of my 3.0 MerCruiser stern drive alpha 1 Gen 2 I just uploaded a video I'd appreciate it thank you

Great video!!

Lol!! Anyone else notice he installed the impeller in the wrong direction!?! I guess it didn’t matter if it pumped water!

Just watched your video, a couple of?'s will the housing slide all the way down If the key is not aligned right ? I think I put the key in the groove put it was hard to tell , but housing fits flush ? THANKS..

Hi, great video! Is there another impeller in the engine room?

Chris, After I reassembled the lower unit, I cant pull it out of gear. It seems as if it is stuck. Do you have any suggestions?Thanks

My Impeller didn't come out with the cover. How do I get it off?

thanks for doing the video

Does cleaning the shaft breach YTs terms of service?;)

First thing I noticed...lol😂.. backwards impeller

Thank you!!!!!

Hi Christ , so if the impeller not working won't pump water to the engine even if the water pump works ? Little bit of help please.

impeller vane should be pointing right . this gentelman installed the impeller the other way around.

did i hear you have to have it in gear??? cause i done took lower unit off and and that was not mentioned in the beginning!!!

Do we have to drain the gear oil first ? I removed my lower unit today and as soon I took it off oil start dripping from top on the floor , was a big mess

Hey man what order did you do the other gaskets? I bought a kit and am trying to replace mine and don’t know the order. Oil has been leaking out the bottom of my water pump and no instructions came for the water pump kit. I thought it was the o ring and have taken the lower unit apart about 7 times now and I found it’s the bottom of water pump. Would appreciate it
