Fuel/Water Separator

I got a 1988 20hp Evinrude with the boat I recently picked up. I'm attempting to do the tune up myself once I figure out out to remove the lower unit. Anyhow, i'm thinking about installing a fuel/water separator from the gas tank to the outboard. Does anyone use these? Have you noticed it's relivance with all the ethanol in the gas?

Have always used them (25+ years) on my offshore boats. Have seen a little increase of water/yellowish fluid during the season since the switch over to ethanol, especially after winter lay up. Thank goodness I had them on when I did the conversion from 100% gas to ethanol as I had 2 tanks to do, a 100 gal and 50 gal and the amount of water/yellowish fluid and gunk was awful... Because of that, I did add a f/w separator to my 16' Lund but honestly I have not seen any indications of water/gunk as yet. Then again, it was easier to empty the 6 gal portable tanks, let dry and re-fuel with ethanol.

Sorry cant help with the ethanol question ..... only run ethanol free in my boats with startron fuel treatment. However i do run a separator on all of them, and never had a problem yet

Just intalled the separator yesterday. I haven't hooked up the hoses yet. Still gotta replace the water pump. I used a $2 cutting board from walmart to use as a mounting plate

I run one on my outboard with remote tanks. Can't say it's helped but I know it hasn't hurt save for the cost of yearly filter replacement! I try to rid any gas from these tanks as soon as I can by using them in lawn mowers, weed eaters or any other time I need extra gas I pour it out of my boat tanks! My boat gets the freshest stuff!

Finally hooked up this weekend. Didn't get to try it out yet.

Good idea with the cutting board. As others have said, you will save yourself a lot in future maintenance costs

Yeah, it was the perfect height for where i wanted to mount it. Score!

Cfh1177, be careful when screwing on your filter, i had the same unit and hand tightened it and the brass fitting pulled right out of the plastic housing, returned it and went buy an aluminum housing.
