How can I id the helm pump? It has no numbers or id plate, just big squae chunks of alumium bolted together.
I know it has to be Hynautic, the rest of the system components are plainly marked, except for the helm pump.
What's the difference between H-21 and H-25?
Can I substitute any hydraulic helm for the hynautic?
Mainguides, Thanks for the info, guess all I need to do is pull the wheel off to determine #. I want to add a station at the deck, not entirely sure yet if I will use a helm with wheel or a dodger hooked up to the autopilot.
1Oldbuzzard, how much are you asking for your spare unit?
