Peggy, I've a new to me Gulfstar 37 that I want to put a fresh water flush new head on. The current head is a seawater flush power head (Raritan I think), but I would like to get the Admiral her own new one that used the fresh water pressure system as flush water instead of sea water....What model or brand do you recommend for what I need? We mostly use the boat for daysailing and occassional overnight. On my previous boat I had a crown II and liked the reliability and rebuildability, but like everyone, I am open to cheaper suggestions as long as they work..Thanks
