Replace Impeller Illmore 6.0

Going to try to replace my raw water impeller this weekend on the boat for my first time. Its on 2012 6.0 Illmore.

Anything I should be aware of or any hard lessons other people have learned that they are willing to share? Planning on getting a gear puller or something to help get it out.

Step 1 I guess is to locate exactly where it is see what kinda weird angles I will be stuck working in.

step 2 where to get the part. People just getting it from the dealers?

no one would happen to have pictures by chance would they. Seen a few post on youtube but not for Illmore motor. cant be that different

check the position of the gasket when jo remove the cover from pump.
be sure you install it the same rotation as removed.

the simplest way to remove the impeller is to turn the pump for and backward if that is at your motor possible.

i pull it with a long nose pliers while turning the pump for and back just a quater turn.

Just for piece of mind I would also replace your rubber gasket that is on the impeller cover...I bought my impeller at my local mastercraft dealer for 45.00, and he also had the gasket in stock.

On my DD I used to remove the housing cover, pull the kill switch, and give the engine a couple of bumps. Made it come out much easier. As previous posters said, make sure your new impeller comes with the gasket; I've never seen one that doesn't.

I just did mine last week.

The manual says you have to remove the entire pump and serpentine belt but I didn't find that necessary at all. 4 Flat head screws, pull it out with needle nose plyers, put new one in, new gasket and done. It was much easier than the manual let on.

Snowman,

I recently changed the impeller on my Ilmor 5.7. I don't know how different that is from the 6.0. Anyway, my impeller shaft has a woodruff key that would keep falling out every time I tried to slide the new impeller in place. I thought getting the old one out was going to be difficult and it was easy compared to the new install!

My advice on installing the new one would be to wrap a zip tie around the impeller and use lots of soapy water. Provided the woodruff key stays in place it should slide right in.

Chris

I've changed a few on the ilmor 6.0s and it definitely makes it easier if you pull the water pump out and put it on a bench. Sounds like a bigger deal than it is. You can try to pull it out with pliers but there is not much room to work with, especially on my x25.

Mine was a bit stubborn -- so once I had the cover off, gave the engine a quick turn, I used a paint can opener (the metal one with a bottle opener on one end and a 'hook' on the other end). Worked great -- the little hook grabbed the back of the impeller and it slid right out. 10 minute job, start to finish.
