I have a Universal M35B diesel in my 1999 Catalina C36 MKII. I want to purchase a spare, Circulating (fresh) water pump from Kubota rather than Westerbeke but need to verify the Kubota part number. I have a V1305 Kubota Block, SN: WC7243. I believe the Kubota part no. is 16251-73032. Can anyone verify this to be correct? Thanks in advance.
