Impeller replacement

[kayjayfech]

Can someone post some pics (step by step) or maybe a how to video on youtube for an impellar replacement on a v-drive? I located mine and have the spare impeller I ordered from bakes, but don't really want to start without a push and some confidence in seeing it. I have read some past threads but they are over my head. Dumb this down for me. Thank you!


EDIT: Excellent video linked in post #15 below.

Just jump in and do it! Here is my dumbed down version that takes no more than 1 beer to complete:

Remove the 2 screws on the back panel for easier access
Take the cover screws out without dropping them (hardest part of the whole process)
Lock a pair of needle nose vicegrips on one of the impeller vanes and wiggle back and forth until it pops out
Align the new impeller and push into place (light tap with a mallet if needed)
Replace cover gasket
Put the cover back on
Put the back panel back on

I replaced mine this weekend. I did not have and locking needle nose vise grips. I ended up using the paint opener you get at home depot when buying a gallon of paint. It fits between the veins and will hook on the back of the impeller. It took me a solid 45 minutes to finally get it out. I would have loved to have the vise grips small enough to grab a vein.

I noticed, it is all about getting it 1/4 of the way out. Once I got it that far out, I gripped the part sticking out with a pair of channel locks and it came right out. New one slides right in.

edit: I now realize I did not have a beer on hand while doing this. I think that was the issue.

One way to make it easier is get some lube in there... the new impellars usually come with a small tube of glycerine, but if you spray some silicone spray lube in there, and bump the engine to spread it around, it should come out easier. With those needle nose vice grips it takes about a good 30 seconds of pulling/wiggling to get it out. No Sweat. Well, maybe a little, depending on the day, and how cold the beer happen to be.

Anyway, yeh, simple. Just be sure to lube the new one going in, and spin the vanes in the right direction, it should slip right on. Don't overtighten the coverplate bolts either - they don't need to be torqued too much, a good solid hand tight should do the trick.

I think you can get the impeller puller tube on ebay for less than 20 bucs. It takes about 2 minutes to remove it. It also doesnt destroy the veins if you plan on re using it.

A pair of needle nose pliers maybe a couple F-bombs later and it'll be out :)

Is it possible to put the impeller in the wrong way?

[rdlangston13]

last year when i replaced mine i tried the pain can opener trick with no luck, ended up going with two pair of needle nose pliers and it came right out, didnt even damage the veins

[moombadaze]

id say pretty much how newty wrote it-simple version



Is it possible to put the impeller in the wrong way?

no, either end goes in first and as soon as it spins over the veins are going in the correct way.

Hey guys just wanted to let you know I completed it last night and it went smoothly except for how tough it was to pull that sucker out. I damaged the rubber. Oh well. I posted a step by step video on YouTube with 4 quick videos on how to do it. Just search for impeller replacement vdrive. Thanks for your help. Saved me 500 bucks from the dealer.

Glad to hear it worked out for you! Even with a damaged vane or two that impeller will still work just fine as a spare. So are you using the $500 "saved" to justify a new purchase for the boat? :)

For the n Ext one get yourself the impeller puller. Its not that much and makes it very simply to crank the impeller out. Just twist the handle and out she comes. It does no damage to even the most pita impellers

Awesome job! I wish more people would post videos like this. Still waiting for a nice oil change video that shows how to drain it through a thru hull under the boat. :)

Hey Everyone,

Here is another web site that does a great job at showing how to replace the impeller. Also, lots of other links that may be helpful if you don't know exactly what to do or if you are a first timer like me.

How often do you think you need to replace an impeller? Yes, when it looks bad, or your having temp issues, but other than that? 1x a year? every 100 hours?

[viking]

i do mine every 2 years whether it needs it or not. Keep the old as a spare in the boat. Cheap insurance imo.
they never seem to want to go out in a very optimum time :)

[wolfeman131]

I'm with viking.

[kaneboats]

That's what I do too. It's about 60-70 hrs. per year in clean fresh water. Not too worried. Probably still overkill.

[wolfeman131]

Like a Pinto w/ $6,000 rims?

I'm with viking.

I am on the 2 year plan as well. The first impeller was still in such good shape it is my spare now. I bought two, one for the replacement and one as a spare. Don't need teh second as a spare now so I hope the second new one lasts until I need it in 2014...

[jmb]

Good idea to keep a spare. I spun the hub on the impeller and the rubber wouldn't move anymore. Just the brass piece. Only a year and a half old. Something to think about. I could have changed it on the water.

[mcdye]

I replaced the first one after first year and then it kept as a spare. I take mine out in the fall, check it over, if no issues, lube it, and place in a bag to put back in the spring. Replace it every 2 years no matter what.

[saskie99]

I just did mine for the first time, only thing that i did that made it way, way, way, easier was spray the impeller with wd40, cranked over the engine and pulled it out. I fought for ten min with no luck with needle nose pliers and after wd40 it was less that 15 seconds!!

I have to say... that is one of the most accurate, but at the same time least helpful videos on the web. Wait ... I take it back ... I did exactly what's shown in the video: headfirst into the engine compartment with my vise grips, spray silicone, bump the engine at 4:20, curse a bit and scrape my knuckles, and emerge with the impeller! Still, you have to laugh -- an 8 minute video of some unknown butt doesn't really seem like a maintenance video when described like that.

Oh, I assume you removed the center wire from the distributor so the engine doesn't start when you crank it?

[kaneboats]

I edited the posts at the top of page 1 and 2 to state there is a good video linked in post #15.

[Buckeye]

So. I pulled my impeller last. No problem getting it out. I'm lookin at eh new impeller and a came with a gasket, a brass washer and another piece that is black and shaped like a washer, but grooved out like its a cap for something. I do not recall taking these two pieces out last fall. Do I need them? where do they go in for before/ after the impeller? Or do I just put the impeller piece in and call it good?
Also, it appears the impeller has a notch, in the rubber on the circle part. am I lining this up with a notch inside? Tough to see in there
Thanks

For the water pump, there should be 4 brass screws to get the cover plate off. A white gasket between the cover plate and the pump housing - usually stuck to the cover plate when you take it off. Unless it rips, that white gasket is reusable if you did not get a new one in the kit. Twist and slide the new impeller. Once you line up the shaft to the impeller, it should slide in a with a little help. I also use a scotch-brite pad to smooth down in the inside of the cover plate - make sure you do not have grooves. Do not overtighten the brass screws when putting back in. Be careful not to drop anything under the motor b/c t's a PITA. Use a towel or box to catch anything. Dawn soap if your kit did not have some lube also helps.

Depending on your brand, there may be additional parts not used in your kit. I know Wakemakers sells the Johnson kit that come with two black gaskets not used in our application.

For the ballast pumps, like a jabsco, there are 3 brass screws to get the cover plate off. A black o-ring that sits inside of the pump housing - sits in a groove. Try not to loose that, it can also be reused, but some kits come with a new one. The shaft has a slot to line-up and just slide it back in. Again, do not overtighten the brass screws.

I'm sure there are some YouTube videos floating around out there.

Awesome. Thank you for your help. Much appreciated.
