Also, while not shown in the photo, there is some kind of electric device stuck in the bottom center of this filter. It's tight fitting and can be pulled out. Curious what it's for. Colby

Colby,

I just replaced the fuel filter on my Suzuki 140. The fuel filter case is very similar to yours. In the Owner's Manual it says to separate the filter unit bracket from the motor before removing the case from the filter head piece. It should rotate fairly easy going counter clockwise by hand. There is an O-ring that attaches to the head piece and you may want to apply a very light coat of water faucet grease to it while replacing the filter. That electric device is probably a water sensor. You should disconnect the lead wire connector of this sensor before removing the filter case/cup.

Colby,
Cat O' Mine is still in the shop with manuals aboard during Hurricane Delta. I last dealt with that cannister in 2017 to get to the engine N2K adapter, which lies under it with a cap plugged into it. As I recall, this is a water in fuel sensor, not a filter, but not sure. I agree you can't turn it until removing it's bracket, and even then ? need if no visible fuel/water floatline.

YouTube demos of owners sawing into genuine Yamaha blue fuel and black oil filters have convinced me it's worth paying a few bucks more for them!

Cheers!
John

Colby,

Let us know what you find in there. There should be a cylindrical paper type replaceable filter inside the unit. Be careful when you unscrew the cup because it will be full of fuel. The filter will look like new but be sure to replace it. Thumbs Up

Colby on the Yamaha f115 this filter spins off lefty loose righty tightly It looks very similar Inside the filter there is a red ring that will float if there is water in fuel .Maybe filter was never serviced?. Basically the Yamaha 10 micron auxiliary filter does the water filtration .

Thanks Jim. Daybreak, no plans or schedule, but probably head down the Cumberland towards Nashville. (I think it's the Cumberland that goes down that way out of Lake Barkley). Likely just go to the end of the first week, then turn back for the second week. All depends on how fast I run the first week, and how fast I think I can return. Smile

Most my photos end up on my facebook now days. Just too much involved to upload here or to other media as well. Colby
