About 20yrs ago I rebuilt 2 Berks in my garage with no prior experience working on them and without purchasing expensive tooling. I now see where there are "how to" rebuild videos on Youtube and at least one of the online aftermarket jet boat parts store has some rebuild videos. I'd try it first before I'd pay to have it done! Good luck!

I 100% agree with this, Tom will help you out no matter what your doing, Do it yourself and buy a rebuild kit and parts from them or have them do the complete rebuild and they will help you and answer ANY questions you may have, GREAT people to deal with, I live in Pennsylvania and Tom and his family has helped me and treated me like a next door neighbor long time friend of the family to the point that I now consider him a family friend and I never even seen or met him. I won't even think about dealing with anyone else about jet boat parts before calling Tom.

I dont think I have expressed this enough guys, but this is a tech site - not a shop directory.

No offense to Tom/JBP....or any shop anyone here wants to plug....but when people come here asking questions "how do I....?" ....telling them to go to a shop right off the bat does nothing for the site. This site is here to help people with their DYI stuff....not just tell them to call a shop. If that was the case I would just have a Jet Boat shop directory on the front page and thats it.

The rebuild is not that bad, I followed the Berk manual on their web site and it worled great.  Just ask if you have any questions, the one thing you will need is the deep socket for the impellor nut.  I made one out of a socket that I cut in half and welded a piece of tube between the two for the depth I needed. 

I have never worked with Tom at JBP but he sounds very helpfull if you need him.  I did though purchase my rebuild kit from CP Performance, the kit came with everything plus an impellor.  CP Perf. is pretty much Berkeley I would imagine you're getting good parts and not the cheap stuff, make sure not to get the cheap stuff!  This whole job cost about $500 with making the tools and all, it's worth a shot to try.  Again, follow the specs in the Berk manual and ask if you are not sure.

really tom?....(shakes head) i give up.

Does anyone else find this thread mildly humorous?

Anyway, hope the pump rebuild works out smoothly. Only part of the rebuild I could help you with is removal of the transom bezel and removing the pump from the boat. I used plastic wedges, sharp putty knives and whatever else I could. I'd rather put one in than take one out...

Edit: In fact, I bet rebuilding the pump once it's on the bench is easier than removal and replacement..

I think most rebuild places don't want to see any boats in their lot.

For the most part everything looks pretty good, I'm sure that impellor nut should come off fairly easy.  The only spots you should use silicone are around the transom cover and around the bowl where the transom cover slides over.  Looks like you should be able to turn this one around pretty quick, let's see more on the progress.

There should be little to no silicone neccesary if the correct seals, gaskets and packings etc are used and I'd Mic your pump sahft looks fairly well worn from the pics  Tom

Tom- Do you guys run the gasket between the transon adaptor and the the transom? What's the trick to get it to seal properly?
