    I just serviced my lower unit yesterday in mine. Had to drop it to remove a stubborn screw and spent an hour getting it back in. Found that (carefully) standing it upside down on a block of foam let me see down in and perfectly align everything. I would say I enjoy working on the KF3, -5, and Mark 6, but I would be called crazy by many people!
