I’ve always had manual heads, and like most boaters, I’ve had clogs (clueless guests), breakdowns, leaks, etc. Never felt the need though for an electric head. However, the trawler we bought 3 years ago had TWO electric heads, the master head bring a Raritan Marine Elegance. I’ll never go back to a manual head! The Marine Elegance has two flush modes, “Water Saver” and “Normal” flush. We’ve found that the electric head is much more frugal with water usage than the manual, as it carefully meters the amount of water used. So the holding tank lasts much longer than if we used a manual head. Also, they both incorporate a macerator which goes a great way to prevent clogs. We’ve spent half a year living in the boat so far, and have never had a problem with either of them. Highly recommend an electric head! As someone mentioned, it’s ideal for guests unfamiliar with using a manual head: just push the button and you’re done!
