I got three new Okuma reels this year. One Mak 30 SEA and two 20s. I had heard about problems with reel seat corrosion, so i decided to get ahead of the issue. I took them apart and applied Yamaha blue marine grease. A few of the screws were difficult to unscrew, but they went back in easy with the grease. No problem with the first two reels, but then on the third one a screw head broke, leaving the remainder stuck in the threads. UGH. My trip leaves next Saturday. I sure hope I get some help from Okuma customer service. Anyone have any idea why there's corrosion in three new reels?
