Great in the salt water, Quite a bit heavier then the aluminium, so it needs to be well secured

Appears to be a solid, very stout casting. It's too early to tell how this grade of SS will hold up to salt water but it replaced a painted, cast aluminum bracket that was corroding terribly. It looks and seals much better that the aluminum predecessor and so far no corrosion.Edit: 4 Years later and virtually no corrosion. A couple of little discolored spots in recesses where salt water puddled but nothing that didn't wipe off. The old, crumbling, anodized or powder coated aluminum brackets were removed from both boats and replaced by these. Worth the cost to no longer deal with ugly components and crumbled, oxidized, aluminum in my fuel filters.

I've replaced several fuel seperators (aluminum) over the years due to corrosion from a saltwater environment. I was about to replace another one when I ran across this stainless steel model. It fit in the existing mounting holes and is milled from a solid piece of SS, the workmanship is excellent, this should last the life of my boat. I will NEVER buy another aluminium fuel separator. Two 1/4" plugs are included and you will need two 1/4" NPT barbed fitting of your size fuel line. The filter size is what is commonly called a 'Mercury'. One reviewer commented the fittings size was incorrect, but he was either wrong or they sent a 3/8" model. Sierra makes 2 sizes in cast SS, the 87-7777 and 87-7776, make sure you order the size appropriate for your application. A 1/4" NPT outside diameter is close to 1/2" (0.54).Update: It's going on 9 years since I installed this, and still zero corrosion- it still looks and works great. I would have replaced at least 3 aluminum separators in that time. I live on the coast on the water, and ALL my neighbors have converted to Sierra SS fuel/water separators. If you're in a salty environment, this is a must have. I'm currently revisiting this page to order another one for a recently acquired jon boat.

Beautifully made, machining is very cleanly done and perfect . Much heavier than I expected. This will be the last water separator 'head' you will ever need to buy. Looks beautiful mounted on the gunnel of my Whaler. Would buy another in a minute with NO hesitation. Highly recommended.

I repowered my Cape Horn 17 three years ago with a four-stroke. The installer suggested adding a fuel water filter to address some of the problems ethanol fuel creates for fourstrokes. The filter is external in-line in the fuel line just before the engine, not internal. In spite of the filter I did experience some problems last year. Thankfully, at the suggestion of my mechanic, the loss of power was resolved by switching gas brands. The existing filter housing really deteriorated after three years and I decided to see if stainless will be superior to aluminum. The description of the housing says Yamaha, so I called the Sierra tech staff to ask about mine, and they said it was compatible. I had been put off by the price, which is around $100 at some marine supply stores but was pleasantly surprised to find a better deal on Amazon. Since the installation was replacement there were no problems. The kit does not include the two parts which attach the 1/2 inch fuel line to and from the housing. And this housing has 1/4 inch ports not 3/8 like my previous so I too took a trip to west marine to finish the job. The port difference worried me. But we went to the island last Wednesday, 10 knots surfing out, 18 knots beating back and it worked like a champ; you always wonder when loss of power means drifting 50 miles to a lee shore. The real test though is that of time and how it holds up.
