Looking to install Racor filter on my 22 outrage. batteries are under the cc console. Welcome suggestions on where to install the filter (i.e. gunnel, transom on the inside?).I have seen them attached to the gunnel but do not think they hold and the filter hardware is not curved for a good fit in the gunnel.

On my 18 OR it's below the gunwale just forward of the motor well on the starboard side. Really can't believe you don't have one already. It's a necessity on any boat with an internal fuel tank.

That's exactly where mine is also (18 Outrage), and should be good location on the 22. I've seen many installed IN the splashwell area, which I think is bad detail.
Search way back in the Forum for discussion on fuel filters. I think the Racor is a waste of money on a gasoline outboard for the additional 1/2 of one percent of water it removes. Initial cost and replacement filters are 3 times more.

We used a RACOR on our diesel engine in a sailboat, the first of three fuel filters.
There was a second filter on the suction side of the fuel pump, and a third just before the suction side of the injector pump.
Diesels don't like water in the fuel at all.
Outboard are more tolerant.
What I do like about the RACOR is you can see the bowl and how much water and gunk is in the filter. You can also drain the water.
I have seen many filters mounted in the splash well (and near the bottom of it, too), but that seems like the worst place for one to be installed.

I was getting ready to install a filter on my Montauk. Any suggestions on a location or brand that you can recommend?

Mine are located in the splashwell on my 22, high on the aft end between the motors. They are easy to get to but are constantly washed in saltwater. Whaler dealer installed, handy spot with wood I guess.
My wood locating diagram shows small wood chunks high in both aft sides under the gunwales and behind the cleats. I may move the filters there one day. Louis' Guardian shows the location area in the photos section.

There is a nice picture of one mounted in a Montauk on page 41 of Cetacea. It is a very clean installation, centered on the inboard of the splash well above the end of the tunnl. The lack of grime in the splash well may be fooling me though :) Mine is above the battery to starboard, on the inside of the hull. Fine, unless I move the battery to the console. Then the center mounting position above the tunnel end seems like a good idea. You're sure not going to stand there.

My Racor had been on the inside of the transom (notched) of my 22'- starboard side, below the aft starboard lifting eye. I just moved it to the inside of the gunwale on the port side between the transom and the splashwell bulkhead; in so doing raised it about 8".

Additional - I carved a piece of teak to accomodate the compound curve of the gunwale that is larger than the Racor bracket so there is more bearing capacity. Fastened the teak block with 4100 and 4 screws.

On my 90 22 OR its inside, starboard side, just in front of the cleat.

Was planning on installing a Racor on my 73 OR 21 as did D Mcintyre on his 73,i.e. under gunwale behind clear deck plate at side of splashwell.
LHG, am little confused by your comment above. You use the Racor but don't believe it is worth it? Are you recommending just using a simple tubular inline filter like Tempo or others make?

Jim - No, I don't use Racor brand, but instead use the Mercury brand, which are now available at most marine stores for about $6.
I'm sure Racor are top of the line, but they are larger in size and much more costly for an infinitesimal improvement. I have never, ever, had an engine water problem with the Mercury separators. I figure they ought to know what they're doing.

Thanks to all for the responses and suggestions.

Thanks for clarification on filter. Since I have Merc, guess I'll look into their unit before any purchase.
