Hi, I have a 5m RIB with a 65hp and a 3.5 Tohatsu.
I tested the 3.5 Tohatsu out last weekend in the fairly strong wind and it powered me back inshore after my 65hp struggled/failed to start and I drifted out.
The Tohatsu's have a grab handle at the front which you can steer with if the tiller is obstructed.
Thinking of modifying this grab handle into a centre tiller.
