Just picked myself up a new in box 50sw at a pawn shop for cheap, any weak points or important upgrades I should read up on? I know it's a good reel, just curious if there's any good upgrades available. Thanks guys!
Post or solid frame?
No upgrades really needed for this reel. If you are using it for Shark fishing you can rearrange the Bellville washers for more drag.
I would surely do a service on it being it came from a pawn shop.
Make sure you service the two speed mechanism, and don'T over grease it. You also need to sync the gears with the antireverse on this model in order for it to shift properly. The instructions should be posted under the left plate cover. Make sure to replace any bearings that show any roughness after cleaning, and pack non spool bearings with grease. I also like to replace the Belleville washers, and any worn clicker parts (ratchet plate, and/or pawl). If you end up ordering any parts, I would get a few 0.3mm shims as well so you can shim the drive or spool shafts as needed.
Check out the tutorials in the International section, and don'T hesitate to ask questions if you run into any trouble.
