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
