Location: Wishin I Was Fishin' | On my 98' Merc 200 EFI there is a fuel / water seperator filter located inside the cowling. It works very well as my bass boat gets water in the tanks often. I push the limits sometimes (nice way of saying I sank it). The bottom of the filter has a threaded hole for the water sensor that's supposed to turn an alarm on when it senses water in the filter. I removed it and put a petcock and plastic tube on it. Every once in the while I drain the filter into a plastic water bottle, which lets me check for water. There really is no need to change a fuel filter every year, just drain the water out of it while winterizing and if you find water do it more often. The most probable place that water will get into the tank is through your breather. There are better designed breathers available but they usually take up more room too.
Be carefull with the add on water seperator filters, most are not USCG rated to be installed inside a compartment.
