Iboats had the best online price for this filter. They also have shipping rates that are lower than most other online retailers of boating accessories. Great company to deal with.

by Emmett from Pearland, Texas on April 26, 2013
This is labeled as a replacement for the Mercury 35-802893Q, but when received the specs reflect it is a 21 Micron filter! NOT the 10 Micron filer I need. I had looked for the specs on-line before ordering and they were not listed. The 10 Micron P/N is 18-7945 according to the West Marine website.

It needs to be changed every 50 hours or once a year.
Q:
My fule lines are 3/8 id, will this filter work for me ?
