have a mini lite. pulled the grease plug and pumped a little grease in. well i could tell there was some water contamination. pumped a few shots of grease in and got to good grease. ran it for a little while (oow) and everything seems fine. no noise or excessive heat at the bearings. i did try to pull the lower bearing cap but it wouldnt budge, so i put the prop back on. should i run it or tear it down now? if i do run it what other than the bearings (if there bad now runing them wont hurt them any worse) what else would it hurt?

A bad bearing will eat the drive shaft. You might post this at the mb forum. You might get more info there.
