Don't know the answer to your question but I am having my engine
rebuilt at TAD and since my old ZF trans is unrebuildable, will have to purchase
a new one. It is around 1500 USD. I noticed that most of the other tranny they have are about twice that in cost.
My guess is for your and my boat
, the ZF Hurth would be fine, and I am going with that.
Besides whats not to like when its made in Italy
