Working on a new to me boat. Spent the last couple weeks getting the motor worked out. Finally got it fired up today thanks to the help of a buddy. Well we immediately heard some weird noises from the pump and pulled the inspection port. The wear ring was just flopping around like there's no insulator in there. I can easily reach in there and move it side to side and even spin it. Looks like a brand new stainless impeller along with place diverter on a Berkeley 12jg pump. How in the world would you even assemble it without the insulator? Or is it possible it disintegrated?

Plan on ordering new parts so I can hopefully water test it next weekend but not sure what I need to look for or order. I'm guessing I should pull the impellor and hope it's still in usable shape and probably measure it. Sounds like getting the nut off may takes some work.

Likley is you may be able to simply pull the bowl, remove the impeller and re use the wear ring with a new insulator assuming no damage occurred to the suction housing bore where the ring is seated or the the wear ring surface on the impeller

having a hard time visualizing how you could even see the wear ring through the handhole with the impeller and bowl installed, let alone be able to move it. you can't even access the wear ring without the impeller removed, unless the bearing is toast and the whole thing ground itself forward.
yes, you'll need to remove the bowl and impeller to get to the wear ring. if you're running the engine with the pump connected and dry, you'll always hear some weird noises. even if there's nothing wrong with the pump.

Well if you stand on your head at just the right angle you can actually see it. My buddy was actually the one who thought something was off and pulled the cover. I didn't believe him either at first. Sure enough I could move it side to side and I could spin it as well. I still don't get it, the impeller looks brand new and the guy who rebuilt the boat knew his stuff.

i'd be very worried about the suction piece until I could pull it apart and check it. that's just not close to right.

I just finished up making a impeller nut socket so hopefully it'll come apart tomorrow so I can check things out. Wondering if the prior owner ran it dry or sucked something up and spun the wear ring. Pretty sure I'm about to find out.

I may be wrong on this or reading it wrong but if you can wiggle the shaft around you may have more issues to check out. the shaft should be supported by the front bearing and the bowl bushing to not allow any "easy movement" ?

Well I got it pulled apart last night and figured out some things and it's not looking too good. My bowl bushings are shot, they were basically gone. There was also some damage to the shaft so that likely needs replaced or machined for a slip on. The bushing also pretty much welded itself to the bowl, hoping that can be machined out. The wear ring spun in the suction housing and that's a little rough so not sure if that's salvageable or not.

Now I've got to figure out if it would be cheaper to rebuild this one (which needs machining) or find another pump (hard to find around here) and rebuild it.

where are you that makes it hard to find? you may just want to replace the suction piece. don't wobble the shaft around if it's not supported by the bowl. bearing located in suction piece may also be damaged.
you're getting to a point where a pro should be used. shaft needs to be aligned so the impeller is perfectly centered. if shaft alignment, from bearing to bushing, is not centered, the impeller won't sit in the wear ring properly, and tolerances will be ruined immediately.

I'm in Iowa so I can probably count on two hands the number of jets I see a year. Here's how things look. I don't have a pic of the suction housing but it's a little chewed up as well.

In Des Moines and thinking of sending it to ARS Marine to do the machine work and rebuild. I have found a new bowl and shaft locally that I may pick up that are on really good shape.

Where in Eastern Iowa are you, I'm guessing you boat the river? Many jets out there? I primarily boat Rathbun lake and I hadn't seen any jets up until this year now we've got 4-5 regulars.

Mostly the river and red rock. Moving to Lynnville ( near Newton) so probably Red rock, Rathbun, and Sailorville next year. I have a spare pump setup in the shop in Keokuk. Jet boats are coming back around the rivers. Mostly because those stupid carp don't jump when jets go by.

Oh nice we'll have to get together sometime then. I typically stay away from Saylorville too many boats on that tiny lake. I am only 15 minutes away though and may start hitting it up on the weekdays once I get this boat up and running. Rathbun is 8 miles from one end to the other but can get pretty choppy if windy although plenty of coves to play in. If you're interested in selling your spare pump PM me.

Finally got around to pulling my pump and looked at the wear ring area and it's a little chewed up. Will get some measurements tomorrow.

Found a guy locally that has a brand new pump still in the crate. He's willing to pull the bowl and impeller and would only charge me $950 for it. I would have to use my bowl, impeller and diverter. Is this a good price? Thinking I know the answer already.

Well it's finally time to start thinking about putting this thing back together after having to replace basically the entire pump. I ended up having to replace the suction housing, bought a bowl off a member here, new shaft, bearings, etc. So far the only thing it looks like I'll be salvaging is the place diverter and possibly the impeller. It's a bronze Aggressor B cut that is in pretty good shape from what I can tell. My concern is the Aggressor should probably be turned down and a new wear ring installed, probably a UWR is what I'm leaning towards. What's it going to cost to send in and have turned down? I also have a mint aluminum Berk A cut I could use. Sounds like the Aggressor B is pretty much equivalent to the Berk A if not better? Should I be looking more towards a AA cut with a 18' 500 HP boat?
