I tested a Galeon 530 fitted with a 90hp Merc 4 stroke outboard a couple of week ago, I am no expert by any means, but it went well, getting up on the plane easly at about 15mph it did 33 top speed.
However at speed it became very stiff turning left, whilst fine turning right. When i questioned this they said it was the stearing working against the prop and was quite common.
I have heard of no feedback stearing, how does this work, is it whays required and can it be added.
Any opinions or advice on this would be welcome.
