The picture of the flipper assembly supplies the answer to something I've occasionally wondered about; the spring return arrangement for the upper flipper. When new, WhiteWater was one of the last games to use the older 'pointed' flipper link (which the one pictured has), and as I recall the very last to have the System 11 era conical-shaped compression spring, used in this case on the upper flipper only. Though the 'new' spring set-up, using an extension spring stretched between the EoS switch mounting and a plate fitted to the flipper pawl, had been introduced on 'Hurricane', the upper flipper on WhiteWater reverted to the older type. As I reckoned it, this was due to clearance issues with the spring plate and a ball guide on the main playfield.
Once the new type plastic link was established in use, ops were encouraged to use it on older games, with a 'kit' available containing the additional parts. I didn't like the new link anyway, and I never found out what the situation was with the upper flipper on WhiteWater (the new-pattern link and the old-type spring aren't compatible). newdos' picture shows the solution - a bent spring mounting plate.
