Kobelt manufactures robust tiller arms in a variety of sizes, built from cast steel and available in Single or Twin configurations. The keyways are machined on size and parallel to the shaft, to ensure no lost motion between the arm and the rudder stock. 

Twin tiller arms are available in lengths of between 13.08" (332mm) to 41.84" (1,062mm), matched to one or more of the 7040, 7050, 7065, 7080, 7085 and 7093 cylinders.

As with all tiller arms and steering systems, all steering system calculations must be verified by Kobelt or a certified Kobelt partner to ensure correct sizing, product selection and configuration.
