Sneakbox sized filter/separator?

OK, with the motor located and on the way, need to gather the other stuff I need to properly protect this investment..... looking for a small filter/separator appropriate for the 15hp, and something that I can mount to the side shelf vertical support.

I think I can fit this: http://www.starmarinedepot.com/Racor+025RAC02+In-Line+Gas+Fuel+Filter.html

Is there something smaller? Better? Cheaper? I like the idea of the sight glass.

TIA, Dave
 
The filter/separtor serves two purposes: filter out solid particulate matter and coalesce entrained/suspended water. Depending on the filter media, the filters will not allow flow once saturated or cause the water to drop to bottom of filter vessel (which must be drained w/a regular frequency.)

Dave,

The RACORs are good filters but look for 10 micron filters. I use Yamaha 10 micron filters on my Parker and duck boat. I keep a spare and strap wrench on each boat since I'm stuck with E-10 fuel.

Is that Racor just a filter or a seperator as well? Not really clear on the website.
 
It is a filter and separator I thought... I will have to investigate further before I order. Not cheap... cheapest I found on-line is $51 and the replacment filters range from $11 to $18. Dave
 
I know it all depends on quality of your mixture and age of your gas, but how long are there expected to last? A season? I plan on having one installed on my TDB.

I change the Racor filters out on my boats (1) once a year or every (100) one hundred hours.

I drain the bowls before every other trip.

By not draining them enough, you can force straigh water directly into your carb's.
 
All depends on if your gass stays clean a/o if you get water in your fuel. I had a standard spin-on filter system on my offshore boat. First filter lasted 3 years, then I got water in my tank. Then I was replacing them almost every trip untill I got the water out.
But since the standard spin on filters are cheap, replacing them every year is good insurance.
 
Carl, how did you know you needed to change the filter? I am looking at the more expensive units with the sight bowl so I know what is happening.
 
Well, when I had water in the fuel, my engine would start to bog down or miss a little. I would then either put a new one on or in some instance, simply drain the water/fuel out of it into a bucket, spin the old one back on and crank her back up.
Outside of noticing a difference in fuel flow, just stick to a schedule.
 
Jim, thanks for the input. I'll use the additives, either Startron or Yamaha brand... I don't use enough gas in the duck boat that the additive cost will break me..., and you are right, I was concerned about where to install the filter in my sneakbox, and leak potential. Dave
 
Jim got me thinking on that as well. I had the water/fuel filter on my duck wrangler so just figure that I would do the same to the TDB.

But, when approaching the dock, I always disconnect my fuel line from the engine and let it run dry and when I get home the gas tank is removed from the boat and put into the shed. I really don't have much of a need or worry to add the filter.

I bought my Yammy from my friend who is the marine mechanic. It was his personal motor for his sneakbox. He advised my to run the motor out of gas eveytime and at the end of the season, remove the plugs and fog the motor. I have had zero issues with my motor. Hook up the gas line, prime it and 98% of the time, it starts on the first pull even after being stored in the off season.

Clen plugs, fresh lower unit grease, and the above seem to work well for me. It seems to me I have seen some boats equipped with a filter separator that was just added to the fuel line - not mounted anywhere.
 
Dave, I just add stabil to my fuel tank when I refuel and I use a small inline filter to keep debris from reaching the carb or injectors. There really is no need for a water seperator on small portable tanks. Just my opinion Jamie
