Should I add a second fuel filter

I have a 2017 250hp etec. Currently single fuel filer on the engine. Does it make any sense , or just add problems to add a racor fuel filter /water seperator inline prior to the engine mounted fuel filter.

Having a quality fuel-water separator filter in the boat is recommended by Evinrude and that is stated also in the Pre-delivery and Installation guide.

I know that having the additional Racor style fuel / water filter is also just a nice and easy way to check things before start up each day.  It is easy to see if there is water in the bowl.  So in addition to being recommended, for me it makes good sense too.

The mechanic that did your install should have insisted on it.  You want one for the health of your motor..

Re: Should I add a second fuel filter

I'm the second owner so I'm not sure what took place when the engine was iinstalled. The current cannistor filter mounted on the engine under the cowling is a fuel/water seportaer filter.  So I do undertand the above repsones even though the engine mounted filter will seperate water it's adisable to add another racor water fuel filter inline before the engine mounted filter. I have no problem doing this but on another boat I did this to years ago the two filters cuased restriction and starved the engine.  I thinking using a filter like this one below?  What Micron cartridge should be used, 2, 10 or 30

 You will not have too much restriction if you use an outboardmanufacturer's or a quality aftermarket fuel-water separator.  Evinrudes are designed for that. The Installation and Pre-Delivery Guide gives the specifications for a filter.

 

The Racor type filter is very popular and high quality.  It is recommended that the filter be either 10 or 28 micron as the engine mounted filter is 10 micron.
