Water separator on Merc 4 stroke

[dmctruby]

I was looking at my "get ready to put the boat in the water list". I have a reminder to check my water separator. I purchased this 2010 2250 RCW new last year. My sales contract has written in the extra's included, one of which says "water separator". I never bothered to look for it last Spring. While doing the winter prep I ran short of day light and didn't really look very hard, thinking in the Spring this year I will get to it. I did remove the battery from the boat for winter prep and was thinking.....humm if there was a water separator installed it would be in that area.......some where between the gas tank and the motor. I recall looking at the gas line and not seeing a separator. So I went to my dealer this week (nice folks) and asked where they installed it. His reply was, I see it on the invoice, you paid for it, but I don't think due to "gas pressure" issues with with Merc 115 4 stroke one could be installed. My boat is still shrink wrapped, I plan to get to unwrapping it the next week or so. My dealer was checking into what happened (to see if they had a record of installing one).

So, does anyone with a Merc 4 stroke have a water separator installed, if so where is it ?

I put one on the stern rail, just above the motor pod. I checked with my dealer and they checked with Mercury who said my warranty would be fine if I took out the low pressure filter. It's the first one in the line just inside the cowling.

Here's the one I got from West Marine (the one on the left):

I have one on mine they mounted it in the motor pod. When you change the filter any spilled gas will stay outside of the boat. It seems to work fine there.
