VP D2-55 - Raw water pump - refurb or replace?

I noted a little splash of oil under the raw water pump so I thought I had best get it off to take a look behind it. I wasn't going to replace the impeller this year, as I tend to replace it every other year. Last year I'd replaced it and replaced the faceplate and impeller (the photo below is of the OLD worn faceplate).



Leaking from here:



On getting the pump off, the impeller itself is actually quite mangled on its ends (so I am very glad I took it apart).







The inside of the pump feels quite smooth. Anyone had this before? I'm going to take the pump back to the bat cave and take it into its component peices, so I could do a rebuild for around £50, or get a whole new one for £300 and keep the old one as a spare.

Edit: The more I look at that impeller, the more it looks like its been run without cooling water... a marina did move my boat without me there - which is almost unheard of for me... I wonder if they forgot to turn on the cooling water?

Hi all. Bit of an old thread, hope you don't mind me re-upping it.

@OP - did you bite the bullet and rebuild or replace?

Any recommendations on where in UK will do a rebuild that you can send in to?

Thanks.

Hello there,

I rebuilt it myself, and it was easy, satisfying and wonderful fun. Taking it off, and splitting all apart on the kitchen table was a perfect winter distraction, helped by my youngest boy. It hasn't leaked since. I can do a write up if you'd like? I think I have enough photos of the process.
