Yamaha fz1 water pump replacement

[@nightdrivers9138]

Hey man I got a 01 fz1 I was out riding around town and felt like I hit a bump but there wasn't a bump, I turned around and went straight home witch was just 1 block away, and found a small coolant leak coming from a tiny coolant hose going to the carb I got it back on then check my coolant it needs some but on the top of the cap I noticed some very fine almost copper color metal shavings, do you think my water pump impeller shaft sheared off ?
