Also the way the impeller was measure was incorrect. You need to measure the blades where they meet the shroud on the large OD and the actual blades from side to side on the small OD, measure the angle also.
-
On a Berkeley Jet, there is no 'taper' on the wear ring unless it's really worn. The ID should be the same for the entire width. If for some reason the OD is tapered (again, it shouldn't be), the tapered end would go in first (towards the front of the boat). The only other possibility is that you have a 'stepped' wear ring, which in that case, the stepped end would go into the housing first (towards the front of the boat).

I have another question for u..on the wear ring its tapered .....where does the tapered side go?

There are a few parts of this video that are incorrect..
#1. A pipe wrench has no business being involved in a pump rebuild. ever. A pipe wrench will always leave a mark
#2 the clearance should be .025 total or .0125 per side. Not .050 total or .025 per side. If this info came from that book get a new book.

@alpianeb7 I'm just a hack and my pump is old as hell but at least you can see what's in there. Maybe a new wear ring and impeller install video next year.

@RGLOVES69 Yeah, I was looking at a water to water heat exchanger there. Your going to need a 1 13/16 very deep socket or a wrench, a bushing driver and a puller to get the impeller off. The bearing is a press fit so access to a press is ideal. Renting the kit might not be a bad idea if you don't have a lot of tools.
