I’m in the process of installing trip 350 verado’s on Donzi 35zf. Replacing
gen1 pump with gen C. Two cylinders. Current helm 40 cc. Merc recommends
50 cc and larger. Should I use a 50 or 63 for this project?
Thanks
Pat

It would be very helpful if the you can avoid a type C failure.
That said...how much do you want to turn the helm? With the obvious Type C issues...I would go with the smaller CCs..it would be easier to turn when your power steering fails when you need it the most.

The issue I have is not getting error messages because the can buss doesn’t recognize the dodge pump, different coding. Maybe I’m wrong about that or maybe there’s a work around.
