This kit fits the new style raw water pump on a Westerbeke 21a. The screws & impeller also fit the old style, which may be a Johnson F4. The old pump used a paper gasket rather than an O-ring. This may also fit other pumps. Those little M4-0.7 x 8mm screws are pretty easy to drop into the bilge. It's nice to have two spares in the kit.

Received just what I ordered...The wrong kit, MY FAULT. Discussion with the vender resulted in assistance with correct kit numbers so I can order the correct kit in the future. I appreciate that help. Meanwhile, I can still use these impellers, just have to get a different gasket. Like I said, my fault.Old news is that 17 years ago when I did the first maintenance on my boat generator I called Westerbeke and they gave me the wrong kit numbers when I provided my pumps Westerbeke part number. Been ordering the wrong kit every two years since. Thanks Steve for setting me straight

I got about 70 hours of run time before this exploded into pieces and ended up in my heat exchanger. Spend the extra $15 and get a westerbeke part.

Update:This impeller spun out on the shaft and had to be replaced a month later. Disappointed. Now my husband wants to stick with genuine westerbeke parts.Original:This is the second identical impeller we purchased. The first one last a little over a year and one blade broke off. Next time we will replace at the annual year service. We always keep a spare on the boat.
