My brother sold a perfect 97 225 Promax and bought a 250xs and is sorry he ever did it. He put one of those grass filters on it and sometimes has to clean it 4 or 5 times on one fishing trip. He say's it's a POS!
All I know is he put a inline filter with a clear plastic top that catches the grass and if it stops up it will over heat your air compressor which is water cooled.
