I'm Assembling the parts for a tiller to wheel conversion on my islander 28. I've found everything except the radial drive wheel (per Edson the islander 28 uses a radial drive when rather than a quadrant). Per Edson the recommended drive wheel is their model 777-8 which is a 16" diameter wheel. Edson says this is for boats to 35'. I've found a good deal on a 777-6.5 which is a 13.5" wheel. Edson says its for boats to 30'. Can anyone tell me the effect of using a smaller diameter drive wheel? (The diameter for the rudder post is the same for both by the way)
Thanks
Bob
