[quote=coastrat]the rudders don't move that much, just up and down a 1/4 turn at a time and they don't turn fast. corrosion hasn't happend on mine yet nor any visible signs of wear. the big 1 1/2" fender washers dispurse the load across a bigger surface reducing friction. there is not much tension on the washers at all, almost none, they act as a shim more than anything. mine work great with no side affects.[/quote]
