I'm looking for advice from anyone who "converts". I just bought a new (2001) boat (my other one got totalled when a guy rear ended me on 20 mile river bridge) and it came with a Honda 90hp jet unit. I bought a new lower unit & prop to put on it. My questions are: When a jet unit it put on, is is normal to remove the shift rod? Is the water pick up tube the same for both? Are there any adjustable jack plates that can give 8-10" of vertical adjustment?
