Sorry guys, but I've been searching the past posts for an hour and seeing tons on impellers, but can't determine:
1) exactly how bad it will be (clearance) on an 03 x2 mcx engine?
I am A huge guy at 6'5" and 270 lbs, and don't work well in cramped spaces.
I am familiar with the impeller change process, as it was a breeze on myold Tristar.
Is this manageable or should I try to take to the dealer?
2) what that part number If ordering from skidim and try myself?
Thank you all in advance,
Stephen

It's hard to do, depending on how much clearance you have between your silencer and the back of the raw water pump, and it's definitely cramped quarters, laying on your side with the rear-most storage compartment panel removed. It would be a lot easier if you don't mind going to the trouble of removing the Silentmaster muffler.

I finally had my dealer change my impeller during winterization this past fall after 6 or 7 years of skipping that maintenance item. They removed the muffler to do it.

There are several thread on impeller changing on MCX V-drives of your vintage. Here's one.

To me and my very untrained eye, it looks like you could slide your muffler farther into the top hose which should move the muffler up higher. Yes it looks like it will move it closer to the pump hosing but if you can move it high enough you might have room to get at the bolts and impeller.

That's exactly how I do my impeller change. Loosen up muffler connections, slide up as high as it will go, and you get enough clearance to make it work.
