Re: I agree with Peggy!
Following Peggy's (usual) great advice, I replaced a manual Jabsco POS with a Raritan SeaEra. The installlation was (relatively) painless and the new head makes "training" guests aboard considerably easier. The only downsides I have come to recognize with the SeaEra is that (1) there is no option to pump the bowl dry outside of shutting off the seacock and briefly hitting the flush switch, and (2) my raw water model tends to fill the holding tanks a bit quicker than the manual PHII I installed at the same time in the second head. As I am on an inland lake with excellent pumpout facilities (meaning convenient and free), filling the tank is not as bad as it could be where pumpout facilities are not as convenient (or free).
