Yes, it was made for the Kubota L2850F, and 1 more listed under compatible equipment. Check the old water pump is marked 17331-73030 or one of the cross references, because makers change parts between serial ranges.

Leaks from the seal or weep hole, noise or whining, overheating, or falling pressure or flow under load.

Clean them right back to metal and fit the new gasket or O-ring dry, unless the engine manual calls for sealant.
No. It is an aftermarket water pump made to replace the Kubota 17331-73030. It is not made by the original manufacturer; the number only shows what it replaces.
