I have the 2 micron racor on my 175 merc and have been told that it is too restrictive. Well unless you burn more than 90 gallons of fuel an hour it is . That dump bowl has come in handy over the years with the bad gas and condinsation that has been trapped in it. The mtr; would start missing or running bad and i would just shut her down dump it out, start it back up, let her idle for a bit and off i would go running smooth. I change my filter probably twice a year at least. I was going to buy the 10 mic; assembly but they were out of them at paxton at the time i was buying so i was stuck with the 2 mic. No regrets! My brother has the 10 and he has no problems with it at all. good luck.
