HOW TO CHANGE THE WATER PUMP (Impeller) on a YAMAHA 150 OUTBOARD

In this video I will be showing you a step by step way to change the impeller in your Yamaha 150 outboard. Im not a professional outboard mechanic but just a guy who likes to do all he can to save some money and perform regular maintenance on his boat. hope this help. please let me know if it does.

[@loopedrevo]

My single Yamaha 150 on my Sea Hunt Triton and I appreciate you taking the time to do this. I'll be doing it soon. Thank you

[@mikejolly3481]

Great Video. Love the low key and smooth approach.

[@davebest6369]

Outstanding video, you did a great job explaining each step and what need to be done and what to look out for, I feel I could do this new time on my Worldcat GB ed. Thanks

[@sg15]

Great video thanks for sharing. Changed the impeller on my F150 for the first time with confidence.

[@elainevlasak4214]

Thanks for a great video, which gave me the confidence to change my water pump out on my 2012 yamaha f-150!

I retired Friday, family is coming up to spend some time on the water and a cabin on the lake retreat next week. I put the boat in the water this morning and "impeller problem," no water discharge. I watched your video, it was/is EXCELLENT. I believe I will make this change myself. Thank you for a great job!!

[@fatarzan1]

Good video . If the metal ring wont budge it is easily defeated by gently heating the cap and softening the plastic ring . Of course the metal and plastic rings will have to be replaced . I like to grease the impeller and housing before reinstallation . Be careful when reassembling the pump housing the wavy washer goes in the middle .

[@Adadslife11]

Awesome video brother. Watched it a couple of times in preparation of changing one out on my boat for the first time. I really appreciate you taking the time to demonstrate it so well.

[@georgeandkatherinedrager3705]

Thanx that was good I just bought a boat with a 150 Yamaha 2 stroke a 2011 it looks very similar The last person who did it put the three washers ect on top of the plastic housing

[@THEBIGA2300]

It’s the little things…

[@kristoffscuba5466]

Nice video. I'd also grease up the top splines on the prop shaft.

[@tommyakse7309]

Good video 😀

[@KevinJ-jp2qx]

good video ty

[@302Camaro]

Great video however I would suggest putting some grease on top of the shaft. Just regular marine grease will do.

[@milanfilipovic9105]

Thanks for the video, any suggestions on what I should do if the anode bolt doesn’t want to come off and the top just keeps spinning? The anode is loose but doesn’t come off while the top bolt just keeps spinning and doesn’t tighten back up either

[@vincejames4432]

Hey I really appreciate your video! So easy to understand and well explained.. Quick question for this video. What year was this 150? And was it a F150XB. (Sorry I might have missed it!) Thanks again!

[@brianwest1501]

Good job. Any torque specs on the plastic housing bolts?

[@chocolingo7423]

Awesome video sir. Any ideas on how to finagle the shaft into place along with the shifter? I am having the most difficult time possible. I’ve got a 2015 150hp as well

[@THEBIGA2300]

Hey Choco, a good pair of long needle nose pliers can do the trick

[@blaster-zy7xx]

I’m looking at this because my shifter control is stuck in neutral and won’t turn to engage forward or reverse; so I was looking to see if we can get to it through the lower unit

[@tonydalauro60]

This is a great video, thank you for this!Quick question.. I was under the impression that you had to drain the lower unit oil but I guess not?

[@THEBIGA2300]

No you don’t, the lower unit is sealed so water doesn’t penetrate

[@wweguy5919]

FINALLY YOU ARE BACK!!!

[@THEBIGA2300]

yeahhhhhhhh bbbaabbbyyyy!!

[@mikep3186]

Do you not grease the drive shaft splines? Great video.

[@scottackeret6916]

Where do these 150s take in the water the lower of the two on the Shaft. yes great job explaining everything thank you

[@THEBIGA2300]

Yes they pick up thru the black pickup grates and there is hold at the top of the lower unit that will pick up some water

[@danieldipeppe1455]

What is the torque on the bolts and how many hours on that impeller

[@DLeopoldi914]

Is all that corrosion on the drive shaft normal? Mine looked similar and mechanic said it shouldn't be that corroded...

[@custombuiltcontractors4118]

What size props are you using

[@Jefferickson-qr1kl]

I have a f150 left handed , should I spin drive shaft counter clockwise as I slide plasic cover over new impeller? thanks great vid.

[@susanzimm239]

no the motor spins clockwise the difference is in the lower unit

[@davez4177]

Thanks! Question, I have a 2010 F150 that gets overheat alarm only at idle speed after about 5 mins of idle. Pee stream is going OK, but maybe takes longer to get started. My boat is used in fresh water, clean lake, water is on "hard" side (some lime). So this looks like bigger job than changing the PRV (Poppet) valve and also the thermostat. What order would you (or readers) start changing these parts? I'd like to start with the most likely culprit, obviously.

[@THEBIGA2300]

Hey Dave, tbh with you I would prob just go ahead and change all 3. That way you essentially eliminate the problem and with it being at 2010 it wouldn’t hurt. Good luck man!!

[@chrisjarek7021]

Great video Can you tell me what size of propellers you run I run 13 3/4 x 21 and feels like is over propped Thanks

[@BjBnet]

Depends on the weight of your boat. I have a 23p on my ranger fish and ski. 21p might be better. Maybe in your case a 19p would do if it's a heavy boat or a different prop altogether. It's it's a 4blade, try a 3. Hope this helps.

[@rotfan77]

Is there anyway to test the new impeller you just put on to make sure it’s working before you make a long drive to the water? I bought some muffs but they don’t seem to work, I also put the bottom part of the motor into a storage container and filled it with water it barely covers the black screens on the bottom of the motor but no water is coming out not sure if the water should be any higher or if I didn’t do a great job on my impeller install?

[@THEBIGA2300]

Yes there is a way to test it but you will need a container that will totally submerge the lower unit for it to pick up water like it’s supposed to. I have a plastic barrel that I can use for mine like that and they also make a heavy duty rubber bag that you can fill up and flush them. The black screens on the lower units are just for water pickup once you are up to speed. Good luck

[@WillyMcCoyBBQ]

Good stuff man. Like the little Pro Tips you give. Do you know if doing this will it void the warranty ? Thanks man.

[@THEBIGA2300]

Shouldnt void warranty but I would use Yamaha oil, filters and keep receipts if your worried about it

[@WillyMcCoyBBQ]

@@THEBIGA2300 I always do. Thanks again

[@htownsfinest87]

Gamefish gang gang!!! Did a 125ish mile round trip Saturday, noticed my starboard had a weak pee. I would say about 30sh percent less than the port throughout the entire rev range. It did get a little worse by the time i got home, never got warning lights though. Will be tackling the impeller wondering if it's deteriorating

[@THEBIGA2300]

Gang Gang baby!! Yea I would def swap it out! You dont want to get halfway out there and the alarm go off!

[@htownsfinest87]

@@THEBIGA2300 there was a trick i learned havent tried but someone said if your impeller fails hook your flush port to the raw water b and run it, not sure if that's a good piece of advice, whats your thoughts? My gamefish 27 won't plane on a single 150 so if i could keep both up in pinch than let it rip 🤣

[@ronkelly7894]

@@htownsfinest87 I’ve been told the the flush port does not put any water to the impeller. This is why you are never supposed to start your motor when hooked up to your flush port or you can burn up your impeller. Now if you’re out far and your water pump fails, I guess you are going to be replacing your impeller anyway so maybe you’ll be fine to get you back.

[@cm365dnf]

If you do this yourself does that void your warranty?

[@MrCampbjam]

Great job on the video. Can you tell me what kind of transducer you have? Maybe share a picture. Never seen a mount like that

[@THEBIGA2300]

I have the lowrance/simrad 3 in 1 transducer with side scan. I was having a problem with losing bottom at higher speeds and lowrance makes a mount that enables you to mount to the bottom of the hull which gives it good undisturbed water all the time.

[@MrCampbjam]

I have a 2015 Sea Hunt 25 GF as well. I have the Raymarine Axiom 12s with RV-100 3-1 transducer. I have the same issue. Real common without thruhul from what I understand. I have a G rated Facebook site as well. Saltwater Fishing Gulfcoast if interested. Again nice job on the video

[@THEBIGA2300]

I don’t have any videos on it but you would need to turn the shift shaft to the middle position on the lower unit and realign and install

[@chrishill3934]

Is "never sieze" the actual name of the product you use? Is it a marine grade lubricant? Or does that matter? Great video. I just don't want to use something inappropriate when I do mine.

[@THEBIGA2300]

I think it’s actually called “anti-seize” you can find it at any auto part store

[@rotfan77]

I’ve got the lower unit 1 inch From going back all the way in it seems to be hanging up on something but I can’t figure out what?

[@rotfan77]

Found another video, it showed if you put the boat in gear and just put the prop on enough to jiggle it a little left and right as you’re pushing it up, it allowed it to slip right into place.

[@gcogs2296]

Is there a special formula of Never Seize you use? I see there a few different kinds. Thanks.

Shouldnt, it could make the overheat alarm come on but that would be it

[@dennissandvig2148]

Did you have shifter in forward or neutral position?

Neutral

Grease the spline where the drive shaft goes into the engine. Makes next time easier.
