I checked all of my reels by marking the spool. some make it allmost 4 turns and some make it allmost 5 turns. They must be the 3.8:1 and 4.7:1 ratios that were mentioned. Thanks for all the replies. Next question, are the bearing supported worm gears something that you can buy from Abu or are they only available form custom dealers? If so what model of new reel has the bearing worm gear parts and what are the parts numbers? Thanks guys.
