Is there a guide on replacing the impeller on Raptor 400?

[haknslash]

My dealer is wanting to charge me a couple hundred bucks to replace the impeller this spring when I have the boat summerized. Figured now that my 2-year free dealer maintenance incentive is coming to an end I need to start wrenching on the boat myself to save some cash. Just looking for some tips on what all is involved and what part #’s I need to order. TIA

Edit- I may have put this I the wrong forum section. Please feel free to move to the service section.

This is the impeller kit.

Not sure on how easy the pump cover access is in the max, it is very easy on Supra’s through the surf locker engine cover.

4 bolts, needle nose pliers to wiggle the old one off the shaft, use grease supplied or WD40 to install and use new gasket.

Two beers and 30 min.

I could easily turn that into 6 hrs, 2 broken tools, one lost bolt, and 3 trips to the auto parts store, and a 1/2 bottle of bourbon and a wellness check from law enforcement.

Buy a $50 impeller puller, makes the job so much easier, about 10 minutes, but take 3 beers so it lasts longer, lol

Ha, love it!!!

But seriously, depending on the boat access, it’s a 1.5 on a 10 scale.

Ask my wife. I have the knack of making the easiest things into ego driven death marches towards professional help. Mechanical and emotional.

Thanks guys for the info. I haven’t removed my side panels on my Max in quite a while but hopefully there is plenty of room to work.

[BigOrange]

Access for me in the mojo is pretty easy from the port ballast locker with panel removed. Just make sure you don’t drop your small screws that hold the cover on and an impeller puller is probably worth it.

You can bump the engine a few times during to help get it out.

I agree, impeller puller and it's a 10 to 15 minute easy job. I've done it 4 times already. Dealer wants to do it for $200. I did it in 15 minutes for $45 and i didn't have to tow it in.

If you don't get the puller, take the faceplate off, smoother some dish soap on it, and then bump it over once. Worked for me and was posted on here a few years back.

Any tips on where to order the impeller pulling tool?

Just changed mine for the 1st time Sunday, after a couple of hours, sweating like a madman, speaking in tongues & cutting the hell out of my hand with pliers, finally got my old one out by destroying it with a flathead screwdriver.

[bobby1110]

Anyone got a part number or link for the puller?

On our Makai, its super easy to get to with the one divider pulled out. I use paint can openers to pop it out, probably be even easier with the puller. Use a little dish soap when re-installing the new one so you can spin it the right direction sliding it in.

[MJHSupra]

Without a puller it can be hit or miss. I've had some that will come out after a little bump on the motor. Others times that f%#ing thing just did not want to move no matter what I tried.

Right tool for the right job.

You want to be choosy about what you use to lubracate the new impeller as some lubricants can damage the impeller or other components of your cooling system. Glycerin is a good choice and is inexpensive. It is found in the first aid section of your local pharmacy.

I would actually be cautious more with glycerin (mineral oil) as its not compatible with some elastomers as one might would think. We've ran tests at work on all of our compounds (note compounds might be different than an impeller, but definitely similar to engine seals) and it has shown some to loose 30-50% of their strengths in a 72hr heated soak test. Should also note I haven't ever ran a 72hr heated dawn dish soap test but I have used that method for over 20 years without issue so take that for what it is I guess or better yet talk to your local shop and see what they recommend you use to ensure you are ok.

[RUGER761]

Not the same kit I've used before (different pump than ours) but this one comes with lube which is a Glycerine based lube, so looks like you are safe based on that, I stand corrected :)

I just used water and spit when I changed my last impeller. Started with spit, ran out and then used water. LOL! It worked.

Did mine yesterday. With the puller was a breeze.

I though the difference in the spline design was interesting (running two different ways on the stock impeller vs all the same way). Any thoughts on this or doesn't matter?

Or was it the same originally and got angled during the 70 hours of use?

Are you talking about how it looks smashed at the top of your pic?

[dyrmz134]

Yes, that's the factory one. Bottom is before I put the new one in.

[MJHSupra]

This is the impeller sitting inside the pump. Notice the clearance differences.

That looks normal. Pump housing isn't a perfect circle. And they do tend to stay bent from use. If you let it sit out in a warm place long enough it will probably straighten back out.

Thanks folks!

Got the impeller changed, finished up with the vent lines for the new WM rear bags and moved the sensors up. Ready for a water test before the season officially starts.

[HFarr]

Awesome! Let us know how it goes and take pics of the new wave!
