Review on 🔧 Stainless Steel 3/8" Fuel Water Separator Bracket - Sierra 18-7776 by Mike Marks

I was fed up with the horrible corrosion associated with die cast aluminum cases but was concerned when I read the reviews of this stainless steel model and realized that it will rust even in marine environments. But I think I found a solution. I bought a zinc rod (also from Revain: Martyr Bombardier Johnson/Envinrude Anode Power Trim and Tilt Models Martyr Bombardier Johnson/Envinrude Anode Power Trim and Tilt Models) for about $10. I used a grinder to smooth out the casting marks on the anode and then drilled holes to attach the stainless steel fuel/water separator housing. A ground wire was attached to share the anode's load with the rest of the boat. UPDATE #1: After a month in and out of the marine environment, the zinc has started to oxidize, but the stainless steel components remain pristine (as seen in an actual photo of wet stainless steel a few miles off the Florida coast). UPDATE #2: After two months in the marine environment, two spots on the stainless steel component showed signs of rust. At this point, the rust is so superficial that it can be rubbed off with the touch of a finger. I cleaned the surface and then treated the stainless steel component with an anti-rust spray. UPDATE #3: After about four months of use, the stainless steel components showed no additional rust, but both the brass fitting and the zinc anode were further oxidized (as can be seen in the photo where the item appears to have turned brown with anti-corrosion spray). UPDATE #4: Now in use for over 8 months. Without further intervention, the device status remains stable and unchanged. No additional oxidation occurred on the stainless steel component. UPDATE #5 Now in its second season of use. A makeshift ground wire broke a few months ago. Despite the loss of the ground cable AND no additional anti-corrosion treatment (see update #3), only slight traces of rust are visible on the stainless steel component (see last picture in the row). UPDATE #6 After more than 18 months of exposure, the device remains unchanged. from the previous state.
