[@MrCalman65]

Big thank you from Australia mate. Mine didn't separate quite as easy as yours. Beer and a big rubber mallet was required. Couldn't believe the amount of gunk inside there!!!!

[@Discoworx]

How old was the pump impeller do you think? Mine's 7 years old but has only done 30 hours of work so debating whether I do it or not. Thanks

[@MrCalman65]

If your boats not overheating I wouldn't worry about. I have an old 1997 Bayliner Capri that bought second hand so god only knows how old the impeller was. It was running hot so I thought the impeller was the cause. Turns out the exhaust elbow had never been changed and was absolutely rusted up. I fixed that as well as changing the impeller (which was fine) A mechanic would tell you its always a good idea to change the impeller regularly. Its an easy job as well.

[@Discoworx]

@@MrCalman65 thanks for that. I've had 2 boat mechanics now tell me it should be fully serviced every year. Just seems OTT. Manual says 3 years or 300 hours on the drive. Mine's done 20 hours on the river and 10 at sea. What's the common failure mode? Gradual raise in temperature or do they start to cook quickly?

[@jayproff342]

You just don't know how much money you are saving boaters. Much appreciated!

[@captainjaybird]

Awesome! thank you for your tutorial. it gave me the confidence to try it my self and it all went smoothly. My boat - 2005 model - never had the impeller changed so I thought a proactive change was better than a reactive change. I was scared at first but it was actually very easy - took me two hrs by myself. I figured I saved over $250 - thanks Eddie!

[@122436Joe]

Thanks man! You Rock! The Sealoc manual is great if you are in a shop taking the whole drive apart, but this shows how to do just what needs to be done.

[@TONYDAVIS6452]

Fantastically helpful and well explained! Thanks for saving me hundreds of GBP. Best Regards from David in Scotland (new to boating)

[@jkgkjgkijk]

Thank you for this great tutorial on changing the impeller. The woodruff key was also a good/important point of mention.

[@1951RKP]

Great video. I had never change one of these before. It helped that I am very mechanically inclined understand what was going on. Watched both videos and change one feeling like I had done it before. This really helped and is much easier to understand than a manual.

[@ronaglenda]

Awesome and helpful video! Great tips saved a lot of time for sure. Thank you for sharing!

[@irnmikk1]

EXCELLENT how to video!! Great job!

[@rast5137]

Great video! Not quite sure why there were and thumbs down...I felt it was informative and so helpful. Thank you so much!!

[@isaacespapa1]

He failed to explain a few key things such as how to refill the drive fluid, hoe to create an air lock when doing so ect...just an incomplete video.

[@franciscocovarrubias6077]

I need to change mine on my stringer omc 3.8 do I have to drop everything or wats the easiest way to do it with out disconnecting cables

[@charlie1826]

Perfect!!! You saved me some $ doing this myself after watching your video. Good job man! -thanks

[@stormstrike1845]

I have a 1997 searay signature 210. Im wondering if my impeller is on the motor or in the drive. Is it likely that I have an alpha drive?

[@BarryB382]

In regard that "vent tube", that tube is your speedometer tube that comes from the front of the out drive without it your speedo won't work. One other thing the author of this video should have included is putting the outdrive back together. One trick is to align that tube to the pipe inside of the outdrive before you place the two parts back together. The other trick is sometimes the splines do not align properly when putting them back together, you must give the prop a spin sometimes.

[@yaitsme4953]

Agreed, The little tube has a push clip in front of the shifter (2007 model alpha 1 gen2) Don't pull the tube off! it has a zip tie around it. Just push the clip release real hard and it will separate, then replace that little O-ring on the lower drive near the shifter foot. The shifter foot should be in the middle during reassembly. Once you get the splines aligned it can be spun.

[@jetboy001]

NOTE: The vent he briefly mentions and points out is actually where the speedometer hose connects.

[@vitalhoma2553]

Yet he didn’t say anything about??? That u have to pop that speedometer clip off first before Separate the bottom unit 😂

[@deeman77777]

awesome job! Thanks!

[@michaelwalkermw83]

all this work I will do on my sterndrive as I learn how to do this work I will save a lot of the Motza by doin all this myself and I knew I will save a lot of money as I do the work my self I will save even more money that's my way of doin things with the 4,3lirer Mercruiser and I knew my boat a lot better over time hope this will help me in the long run this video was informative for an old salty like me

[@srpope80]

Nice tutorial. Good Marine Mechanic work there....

[@jurenahunter5284]

You should use dish soap as a lube for reinstall, not wd40, it will cause breakdown of rubber soap washes away and doesn't harm anything, also just buy a complete impeller kit not much more expensive! And by the looks of that anode it's running in salt probably time to replace! Other than that not bad

[@denebuff]

Hey Ed great Video How long should it take start to finish to complete this job.?

[@beefcakes27]

How do you keep your boots clean through all that?

[@gearycloward9613]

You helped, thank you!!!

[@robocopdrago]

Alpha one gen 2?

[@khbrandon]

Hi Addie. Thanks for your detail video, i was able to change out the impeller on my 2000 Mariah last weekend. It's sure feel good knowing that it's was done right and saved some money too. Now i have a problem with my power trim. I have to use the trailer button to trim it down and up, because the one on the shifter won't work. How do i fix that problem? my boat is 5.0 mercury alpha.

[@mihaceperlin288]

Brandon Nguyen Same problem.... did you fixed it?

[@edwardwerthner7717]

I noticed you don’t pre spray bolt loosened prdts first😊

[@kirkniles4184]

What if I only have 2 bolts on the sides where you have 4

[@overpolished]

Nice job fellas! This is the first Alpha I Gen 2 impeller change video I have found. Very helpful indeed, thank you!

[@bobjohnson3612]

Jeremy Whisler is there a trick to get lower unit back on about 1inch to go and can't get it all the way up please help

[@mihaceperlin288]

Bob Johnson Same problem here.... did you fixed it?

[@rholl285]

why does that impeller look so big compared to my aloha 1

[@jpznkjz]

FYI you should note this is a Alpha One Gen 2

[@charlesmonroe3124]

Is the Gen 1 impeller repair much different? I don't see one repaired here anywhere

[@agarcia128]

Chuck Monroe I know it’s late but the process is the same. The parts look slightly different but the overall process is the same

[@golfwhiskey871]

Nicely done video and easy to follow, but I noticed a critical flaw. WD-40 attacks Buna-N! Second, I don't believe any petroleum based lubricants are allowed by Merc to be put on the impeller in it's housing as that will degrade pump's efficiency to cool the engine.

[@peanutbutterisfu]

Ayee!! How You Doin?

[@steverosensteel5956]

yes,put it in forward before removal

[@HKZBob]

Nice Video, when are you doing a tutorial for a Trim Sending Unit Replacement?

[@outofthebluefishing9570]

you got a internal clog in the cooling system or you forgot about the keyway on the impeller shaft !

[@nedajack]

thanx

[@milkman44107]

I assume this is a alpha 1 Gen 2? Is the Alpha 1 Gen 1 much different?

[@JT-vj6id]

DaddyDubs did you find out if there is much difference between the Alpha 1 Gen 2 & the Alpha 1 Gen 1? I have an 1987 4 cylinder 3.7L Rinker & I think it’s Alpha 1 Gen 1.

[@buckscountyautospa6008]

Gen 1’s use a 3/8” Allen key to remove the zinc over the prop. The bolts and nuts to remove the lower unit are 5/8”.

[@jkgkjgkijk]

That thing was good for another ten years.

[@RusianFreak]

is it just me or does his voice sound like adam sandler?? lol. helpful video btw!

[@ZLOKIRIJY]

Я этих колонок пару тысяч перебрал, а снимал не знаю даже ))))

[@hbrookes]

Thanks...Hope i dont need anytime soon..

[@cone6052]

Can the camera man not moving too fast?

[@KKhhoorrnniittee]

Key, not keyway. Keyway is what key goes into on the shaft.

[@freespeachrulez]

Boy that was no zinc.. you need to replace those right away or you will never get things like your prop off.

[@rholl285]

alpha 1

[@joseehernandez4037]

Woo no I don’t no tha!

[@michaelwalkermw83]
