I have a nc33 from 1978. The rudder cylinder is from Tenfjord 850.
I assume that the size is 225cc
Since 2015 i have a ev-1 from raymarine. That worked well.
We sailed from the Netherlands to Norway with it.
This spring i replaced the pump for a raymarine type 1 pump.
This worked well too, but i stayed up inland waters this year, so no experience on high waves with it so far.
