Buying Guide: Key Purchase Considerations
- System voltage and vessel electrical capacity: 12V units are common on smaller boats; 24V units suit larger vessels with appropriate power systems.
- Plumbing configuration: verify inlet and discharge sizes (commonly 3/4″ inlet and 1″ or 1 1/2″ discharge) and whether your hull uses freshwater or raw water rinse.
- Flush mechanism and noise: consider models with soft-close seats and ultra-quiet flush if cabin comfort is important.
- Macerator capability: assess discharge height and grind power; a robust macerator reduces clog risk during long cruises.
- Upgrade vs. replacement: conversion kits offer a retrofit path for existing manual heads without replacing the entire unit.
- Warranty and service: check the warranty length and availability of support in your cruising regions.
