Default Water separator

This winter while I have the boat in storage in my garage I want to install a Water separator. Itís a 2006 Sea fox dual consol (no jokes please) Iíve looked and I donít see any filter other than whatís on the motor. Itís a merc 150. Any suggestions as to type of separator and mounting location. .thanks

I'd go with a Racor, although others will suggest Attwood, Sierra, etc...evwn a Yam would work. I just have had excellent success with Racor with the see-thru blue bowls...

Mount in the starboard bilge, either on the transom or on an inboard stringer...Primer bulb AFTER the separator...

If you want to really bling it out, sierra makes a stainless mounting bracket. I buy those and then put the racor filter elements and clear bowls on. Mount it someplace out of the elements with heavy duty hardware. You might end up leaning on it pretty good if you need to get an over-tight filter off. http://www.google.com/products?rls=c...ed=0CDQQrQQwAg

You sure? Before you go adding stuff, follow the fuel line from the tank to the engine. If you don't see any more filters, then you'll need to add one.

I just changed mine this weekend. Had the Mercury water separator with no bowl at the bottom. Replaced with the Racor replacement with see-through bowl at the bottom. It was a quick and easy spin on replacement.

If, you really don't have one inline, you'll need to get the mounting bracket as well.

Not familiar with your particular boat, so I'll not be of much help with mounting location.

I've been meaning to add one for the last three years, since I've been running ethanol all season I guess this winter I'll finally get around to it. So as to location, I have two choices; in the bilge where it will be a real pain in the ass to get to except in good conditions or on the side in the motor well where it will be exposed to the elements and of course the possability of blunt force trauma. Anyone have theirs out in the open like that?

Lots of Whaler owners mount them like that...

Yeah Markie1 I looked. No luck. They put the 2 cycle oil container in the rear port storage. I was thinking of putting it in there since there’s room and it would be easy to access.

Yeah I use to work on them and they either put the separator mounted on the transom inside the hatches where battery tray. or mounted on the bulk head inside the bildge. Mounting on outside whould be better so its easy access and can be rinsed and dryed and if its racor its visible for you to monitor the sight bowl and drain water out if any present. Mounted inside is moisture and hard to access if your having problems.

Listen to Cooper, the stainless mounting bracket is a must have. I haven't seen any other kind hold up for very long whether in the bilge or outside.

You nailed it Markie1 and Belzelbub. Took my hand and ran it along the fuel line and there it was. Hell of a place to put it.

So, I suppose you can't see it at all. In that case, there's really not much of a benefit to getting one of them with a clear bowl on the bottom if you keep it there.

So is it safe to mount them in hatches that contain the battery box? Ive seen them up against the transom outside but always wondered if you could conceal it in the hatch compartment that has the battery.

Many boats i've seen has them right next to the battery box. in sea fox usually the case than some opposite side but within the hull bilge area. but CG likes to see the rubber boot over terminals to prevent a spark. trust the fuel separator more than fumes coming from the fuel tank itself.

Hmm, I was thinking this as well, but on my new (used) boat (with an 06 Merc 115HP 4 stroke) its before the filter. My old boat was after and that certainly seems to make more sense. The good news is that with the 4 stroke you don't even need to prime it, but I think I'll still switch it out...

Some put forward the argument that fuel should be "pulled" through a filter (primer bulb between the filter and engine) not "pushed" (primer between tank & filter) based on pressure thinking but it really doesn't make all that much difference.

The main point with putting the primer after the filter is any junk is trapped by the filter before it clogs the primer bulb valves.
