1997 Montauk, where is the recommended location for a gas filter serving a 90 hp Mercury.-

On my 99 Montauk I mounted the water separating filter on the forward side of the splash well.

I think a water separating fuel filter in a boat with on-deck tanks is not necessary. This does not mean there is anything wrong with having one. I just think it is overkill and over-clutter. BW does not install them on the factory rigged boats (without internal gas tanks) for a reason - because they are not necessary.
Boats with internal tanks are susceptible to water condensation inside the cold aluminum belly tanks during certain climatic conditions. For those boats, the water separting filter is necessary. Moisture gets into these tanks via the vent line, condenses on the cold exposed top and side surfaces, and drips water into the gas.
If you're worried about dirt particles in a bad batch of gas, you can use the little in-line Tempo fuel filters.

I have seen many Montauks with the filter/seperator mounted on the starboard side at the stern.
In the interest of floor space I mounted mine on the starboard side, inside the console. The primer bulb is right there, too. That did require extra fuel line length and it is awkward to get at the primer.
If I had it to do over, I would sacrifice the small amount of deck space and put it inside the starboard stern like the others I have seen.
I think the filter/seperator is a good idea on injected engines, 2 or 4 stroke.

I agree with Larry. No need for a filter on a Montauk. Nothing wrong with having one if you really want one, but it's an unsightly device that adds expense, weight and consumes space and is another connection point to fail. I always tell myself: Keep It Simple, Stupid.

Not needed? Maybe not, but it can't hurt.
Added weight? A pound or two.
Additional cost? Around $35.00, no big deal.
Takes up space? I have a stern seat so had wasted space anyway.
Unsightly? Not in the least.
More possible leaking points? Not if it is installed properly and if good hose clamps are used along with teflon tape or PST used on the threads of the hose barbs.
If you don't want the black filter head buy the chrome plated Tempo as I did, it takes the Mercury, Tempo, Sierra and Aqua Power filters.

Tom has the advantage of having all of the Whaler catalogs, 1958 on up, showing Classic Whalers 13-17', and not one of them with a water separating filter installed by the factory for the pictures. My Classic 13-16 owners manual says nothing about the need for one either. But for my 18 & 25 Outrages, with built-in tanks, it says they are "strongly recommended".
Does anybody know if the new 170 Montauk comes with a factory installed WSFF? What's good enough for Mercury owned Boston Whaler, is good enough for me. Between the two of them, they should know.

Last year on vacation at Hilton Head with my Montauk I gassed up at the usual auto filling station on the way to the boat launch on the Colleton River. After about a good 6 hours of running the engine (02 Merc 90) suddenly began to lose power - big time! Looking over my shoulder I noticed my clear glass fuel filter (from WalMart) was full of brown debris. Stopping the motor and cleaning the filter took about 5 minutes. No fancy canister, just a short 2" filter element in a plain glass fitting. It got me home and was good to have. Would the inboard filter on the engine caught the debris, probably. But using my pre-filter keeps the primary filter clean(er)until I have to rely on it, hopefully safe from clogging. No moisture separator though, just a filter - KISS. My $.02. Ken

Other than some I/O boats the addition of a water separating filter is generaly a dealer installed option.
Just because Whaler doesn't install it at the factory doesn't mean that it isn't good option to have.
There probably has never been a Montauk come from the factory with a water separating filter installed.
Nice thing about being a boat owner is: I am the captain and can do anything I want to.

My Suzi dealer told me that not having one would void the warranty on the EFI 4 stroke.

Since Whalerbound was asking where to put one of these, I simply thought an alternative position on their need could be offered, which perhaps could save some time, clutter and expense. I thought that was what this website was all about - differing opinions so one can make their own decision. As I clearly stated, I have no problem with someone using one, and doing what they want to with their boat.
Now at least, he can determine if he really needs one, which could very well be the case.

Thanks for the good advice and suggestions. All the input is greatly appreciated.

I apologize if I offended you Larry.
A statement from someone of your reputation and stature carried a lot of weight. If that statement contradicts what a dealer has said, I think Whalerbound needs to know it.
A bit of water or trash has no permanent effect on carbs. In an injection system, $eriou$ damage may occur.

No problem JB, and I wasn't offended.
Actually, this fuel filter situation can be really confusing, as you have indicated with Suzuki's recommendation. Here's another good one - On the 135-250 Mercury Optimax's, they say a water sperating fuel filter MUST NOT be used, and will void the warranty! Go figure.
My EFI 200 Merc's have an onboard water separting fuel filter canister that is quite large, almost the size of the regular ones. It is alarmed in case it's full of water. So they are obviously concerned, like Suzuki, that water is a problem for EFI systems. I still do have the conventional water separators on mine, as the first line of defense.

No sense arguin' the pernt. A feller can hold his pants up by wearin' both a belt and suspenders, if he likes. After all, it cain't hurt:-!

Can't hurt to have another filter? Better think that over a little more. Just got my motor out of the shop. The mechanic replaced the fuel hose with inline filter and told me to never add an inline filter to a motor that had an internal filter. He said it is not just a waste of time and money, but also a common place to start a vacuum air leak in the fuel line.
