    Default Fuel Filter question

    Hello all,

    I'm in the middle of 'summerizing' my LSV as well as tackle a laundry list of mods. I'm wanting to change out the fuel filter and I noticed mine is a 'Mercury Mercruiser PN 35-864572' inline type filter. Since this boat is recently "new to me" I'm not sure when the filter was last replaced and if this is the correct filter? Does that sound like the correct filter for an Assault 325?
    Also, I see some guys going to a fuel/water separator type filter.....thoughts?

    Thanks
    Steve

    I used a WIX 33299. That's what was in the boat and what I replaced it with. O'Reilly's auto about $12

    Awesome, thanks for the replys guys! I'm liking the $10-12 down the road option vs the $40-50 mercruiser one. I was hoping something from Napa would work but this being my first boat I just wanted to be sure.

    Seeing all of you that owned or still own 08 LSV’s I’m hoping for help!

    Had what I think is my first vapor lock. Owned the boat since January. Put maybe 25 hours on it in total just passed 400. Haven’t had any issues but it stalled a couple times after a start and idle (after being out on the water for a while with no issues) was able to get it started back up and never had issues the rest of the day. Not sure when fuel filter was replaced last. I see the WIX part at oreilly. Where is the fuel filter located and how do you replace it? Can’t find anything in manual. Must disconnect battery first? And simply take out old and install new? And make sure no gas drips into bilge? Thanks in advance for any help!

    Running the blower might help with heat buildup especially after youíve been running for a while and shut it off.

    On my 08 outback v the fuel filter was forward of the v drive on the starboard side stringer iirc (itís been a while but I feel like it was in that area). Just follow the fuel lines from the fuel rails and youíll find it. No need to disconnect the battery, just leave everything turned off.

    I have also been experiencing what I think is vapor lock this summer. I have had the boat 11 years with no issues until a couple trips ago. Mine is a 2006 Launch 21V. The last trip after running the boat in the morning and then hanging out in a cove for awhile I cracked the hatch and then ran the blower for awhile and had zero issues. I have also heard of people wrapping a cold towel around the fuel pump or even spraying it with cold water. I haven't tried that yet, but will next time if we have a problem. Good luck!
