I have just purchased a project
boat which has a steering
device which is new to me - see attached pics- the PO has placed a differential from a Blitz truck bolted onto the rudder
flange (inside the hull
obviously) and had a chain sprocket on the drive shaft which was turned by a hydraulic pump (moved manually by helm
and by autopilot
An experienced boat-builder tells me that the arrangement is very reliable and fail-proof but it is very heavy and I am wondering if I should replace it with the usual hydraulically driven quadrant (I have acquired a spare quadrant recently). Is anyone familiar with this arrangement and prepared to offer advice one way or other?
The diff has a sort of loosely-attached arm with sprocket and I am uncertain as to its function
