Heavy Duty Hydro Tiller Arms- these made in the USA tiller arms are primarily designed for 60 and up nitro riggers, gas sport hydros, thunderboats, etc with right side rudder mounting. They fit into most popular transom brackets like Speedmaster. You will need to notch and redrill (easy) the 4-40 sheer bolt hole a little further down on Speedmaster and some other blades to take advantage of the wider, far more stable mounting of blade on the tiller arm. The pushrod control horn is extra thick for tapping to 4-40 and using the much stronger ball link ends instead of clevis pin ends. $20 each plus priority postage. Unfortunately due to local covid restrictions accessing my post office is a royal PIA so US shipping only until that changes.
