Troubleshooting & FAQ

Q: How do I know if this filter fits my engine?
A: This filter is specifically for MerCruiser sterndrive and inboard models from 2004 and newer that use the Gen III fuel cooler system. The most reliable way to confirm fitment is by matching your old filter's part number to 35-892665, 8M0204703, or Sierra 18-7715.

Q: What are the signs my fuel filter needs to be replaced?
A: Common symptoms of a clogged or failing fuel filter include engine hesitation, loss of power, sputtering at high speeds, stalling, or difficulty starting. Visible water or debris in the old filter is also a clear indicator for replacement.

Q: Why is it important to use a water-separating filter?
A: Water in the fuel can cause poor engine performance, corrosion of fuel system components, and significant engine damage. A water-separating filter is essential for removing emulsified water from gasoline, protecting your engine and ensuring reliability.

Q: How often should I replace my fuel filter?
A: It is generally recommended to replace your fuel filter annually or every 100 hours of engine operation, whichever comes first. Refer to your engine’s service manual for the specific maintenance interval recommended by Mercury.

The king size pillows do not offer the same firmness and comfort as the standard size.
Color: White, Size: King (Pack of 2)
I buy a lot from from Amazon and this is my first negative review as this was one of my biggest disappointments. I have bought 7 sets of this Basic pillow in the Standard size over the past 4 years, for my home and my boyfriends, using them both to sleep on and for my pillow shams. I love these pillows and my guests do too, best sleep ever and I have tried a number of expensive pillows prior to this. So when I recently purchased my first king size bed, I bought two sets of the king size pillow of this same brand, and I hate them. They are not the same as the standard size as they are flat, and no matter how much I tried to fluff them up, they fall flat in filling and firmness. After a few restless nights using my new king size pillows, I used the standard pillows I purchased in the past and there is definitely a difference. I see where there are different reviews/opinions on this, but this has been my experience. I will be complaining to Amazon, though not sure there is anything they can do since I used them.

Ok, not as good as before, put in dryer to fluff!
Color: Grey, Size: Standard (Pack of 2)
I have ordered these a few times in the past and loved them. This time they came rolled up and vacuum sealed. Doing that made the pillows flat and feel worn out. I was going to return them, but read that putting them in the dryer on low heat for about 15 minutes helps fluff them. I did that and it definitely improved the pillows. I'll keep them, but they're def not as good as they were a few years ago.
