Replacing Yamaha Outboard Water Pump Impeller and Housing DIY Yamaha 200, Yamaha 175,Yamaha 150 ,250 

Great video. It made my impeller change a breeze. Can’t thank you enough.

Captain I’ve been watching your vids since the jet boat and finally I’m able to afford a 19 ft used boat. Been rewatching your vids and sucking in all the info. I pick it up Saturday and can’t wait. I appreciate all the insights on the diy and plz keep them coming. Look forward to finally getting out on the water after 6 plus yrs of dreaming🙏

Saludo amigo, bendiciones.

Thanks for the video. FYI, petroleum grease / lithium grease will cause elastomeric rubber to degrade, swell or rot out. It’s best to use silicone grease or nothing at all on the rubber o-rings.

Captain you make all this stuff look easy. Putting on a clinic as usual. Really enjoy your attention to details.

by far the best video out there for me....all the problems i faced good job...good filming...all the details thank you so much from Rhodes ,Greece

Hi Capt.... this is one of the best 'how to do' videos on RU-vid... Thank you!.... The last time the mechanic did this on our Yamaha, he broke that nylon nipple when re-installing the lower unit. Instead of me having to get the boat back on the trailer, and taking it to their shop (which is a major pain-in-the-stern ☺for me), he came to my house in a work-boat, dropped the lower unit and fixed it all with the boat on the boat lift. He's a great mechanic, like you!

Excellent tutorial on changing an impeller. Having been born and raised in Miami and working there for many years I had many Cuban friends and co-workers. I noticed several things about their English pronunciation . One thing was that “B” and “V” sounded identical when you called Yamaha “Jamaha” it took me back to Miami days. Thanks for your fun videos.

Now is the right time to do maintenance before the good weather begins again. Great video as always, can’t wait to see you in paradise again.

Captain, it's great to see your warming videos with a t-shirt while I'm in 18-degree temps! Enjoy buddy!!

That looks just like I did it 24 years ago on a Yamaha 175, Captain. For Woodruff keys, I start out with the biggest chisel I have and when replacing. Getting that impeller started is a pain sometimes because you think you are going to damage it. In addition, I use Scotch-Brite on the vertical shaft and the prop shaft to keep the corrosion down. ( I used to work part time at several marinas and did just about all of my own boat maintenance on Mercruiser and OMC outdrives, grew up working my Dad's boats which where I learned). Great job.

Excellent and helpful

Thanks for doing this WP video. Will be doing my f150 soon and your demo shows all the tricks. I've done 50 hp and 15 hp but never a motor this large. I hope mine goes as well as yours did.

Nice clean job Captain, ready for the water!!

For any other F200's owners who put it all back together and get a bad clunk at low RPM's (it sounds like prop chatter, but worse)....preload the the shaft/pinion space by PULLING UP ON THE DRIVE SHAFT while hammering down the metal collar over the plastic bushing / 3 washers. Its a lot easier to have someone help to do this step.

Nice work. Pro tip I learned from an older gentleman that worked in the outboard racing business. After removing the plastic housing on the water pump. Remove the 2 alignment dowels on the steel plate and you can remove the plate around the woodruff key without needing to take the key out. The hole in the plate is just big enough to slip by it. Saves so much time and no need to ever remove the key, just clean around it.

Great tutorial captain. Stay safe and tight lines

You always produce some good videos. Thanks!

Well done Capt. another stellar vid

Awesome job captain 👍🏻

Good Job! Looks like you did that just in time! 😎👍⚓🌴

Great video as always. I suggest using Dawn liquid soap while installing impellers into housing. I have twins Cat C18 and they go in like butter. Best of luck and keep on fishing.

Nice job keeping up with the maintenance cap! 🤙

Thanks Cap! Will need to do this on my 300hp Yamaha soon.

Nice video Captain… I have a quint and let me say, it’s a pain changing all of them but oh so worth the savings in the long run. Nice

Great job capt. Better to fix it in the driveway than fix it in the water. Stay safe.

What a great informative video!!! Thanks 🙏 😊

Great info as always 👍🏼👍🏼

Confession: Sometimes I "skip watch" your clips. But not this time. I was riveted to what most would call boring. When I buy a boat.... I want to pay you any amount of money to be my modifications and maintenance guy.... Nobody does EVERYTHING as well as you. Certainly not ME. I hit the thumbs up 👍 to feed the algorithm monsters.

Great video

As I watched you disassemble the outboard, I wondered if having some Barnacle Buster in a small bowl wouldn't be helpful. It would be the equivalent of spraying PB Blaster or WD40 on metal parts before trying to disassemble them. In this case, soaking it would soften the salt build-up and ease its removal. Congrats on doing your own service, once again!

Amazing great detail

You should've sanded the side of the new woodruff key down a little bit. Had same issue with my F150. Sanded/filed a tiny amout off the woodruff key and never had an issue since. And use anti-sieze instead of grease on the key too.

Nice job!

eso es importante en los motores marinos mantenimiento vida para el motor👍👍👍👍

nice video. well done. thank you!

❤

Great information

Nice work Captain! I would use a new cotter pin for your prop nut. It can't hurt and gives you peace of mind.

Another great video captain 👌🏽 Looking forward to new video content. Haven’t seen anything new in a while. Hope all is well 🫡

Tip I've seen don't know if it's pro though lol I learned to put a zip tie around the impeller and fold the fins to the direction it's supposed to go pull the zip tie to keep the fins in place. You then put the housing down half way to cover the top of the fins then cut the zip tie, housing slips right on

Great video Capt, been putting off doing this on my Suzuki’s for a while now. But I guess it’s a good time with the weather we’re having.😂

Keep your eye on the harmonic balancer. That’s what went up on mine. Motor threw a low oil pressure light. The balancer hear had exploded and sent pieces down into oil pan.

Time to go fishing!

I've melted the housing and impeller running the engine on muffs before. It looked like I ran it with out water...but I hadn't! I had the dual inlet style muffs and the muff rubber had gotten hard over time..and allowed a lot of water to leak around them.

Hi, I noticed your video shows a step where you remove the old plastic housing intake clip and the cylindrical black rubber part underneath. This step is missed in most other videos on this repair. Does the replacement impeller housing usually not include the plastic housing intake clip or that cylindrical rubber part?

Hello from Big Pine Key. Very good water pump changeout video. All good preventative instructive info for others to follow. I just got my CMOR V-5 South Florida card and two new Penn Squall 30 wide 2 speed reels with 60 lb to go with my two Shimano TLD 25's with 50 lb. Just about set for some serious Wahoo chasin, (and anything else). Weather is 15--20 MPH northerly winds for days now, so gonna install the new wireless kill switch today to get ready for the next fishing opportunity offshore. Do you still have the link on the video for the Stainless Steel anchor? It is the perfect choice for my just over 2 ton 23'-4" boat.

Very nice job cap. Inspires me to do my Yammy. 350 hours on mine and still pushing strong cooling water but don’t want my luck to run out and eat an impeller blade suddenly. Very interesting to see how that housing melted! Are all those parts part of a replacement kit or did you need to order them all separately?

Great video.. Just out of curiosity how did you learn of outboard motor mechanics?

Is that a non-petroleum grease as to not attack the rubber prematurely?

Where did you buy your pump kit? What was your part number? It appears the F150 and F200 use the same kit after 2014.

What year is your Yamaha 200? Just bought a new Yamaha 115. Did you also change the impeller at 100 hours?

I had the same thing happen on my 2014 sportsman 211, melted impeller housing.

Do you use genuine Yamaha parts for everything you did in this video? They cost 3-4 times what an aftermarket OEM kit does. Im trying to decide if its worth the extra money or not??

how do you clean the bottom of the hull while on the trailer? it looks so clean almost as if you waxed it.

We just bought a trawler surprised you haven't looked at them with your mechanical know how we picked up a 34 mainship they are a little slower but burn no fuel and can take bigger seas. 2gph at 7.5 knots like a house you can fish from.

If you flush using the garden hose fitting, never worry about burning your impeller...

A lot of greasing. . . Some grease will affect rubber parts. What type of grease exactly are you using???

Did you hear that Honeymoon Harbor is now OFF LIMITS. No more honeymoon Harbor. It is now a private island.

All Yamaha has to do to better explain maintenance to their customers is links to your videos! 📢📢 Full steam ahead Captain ⚓ #yamaha

Drop the piece you removed it in vinegar. Put grease in the key as well.

no torque specs?

It’s called a lower unit, not an outdrive. 👍 Also, get yourself a small air Hammer. That key will come out in seconds.

Нет, аноды смазывать не надо, почистить и установить, они заберают ржавчину.

Great video
