Sorry for all the questions tonight but had a good wekend on the lake and got boat on the brain. I have an 82 merc inline six 90 horse merc and i don't know if the reeds have ever been replaced or if they should be?is there a life expectancy or an unwritten rule for these things. Is there a good aftermarket/performance brand i could buy or should i stick with oem?<br /><br />thanks<br />dave
