Thinking about putting a jet unit on my 1989 100hp Mariner motor. The boat is a 1968 aluminum deep V Crestliner. Can you put a jet unit on just any boat or is there bottom designs that work better than others? What controls would I need in addition to the jet unit. Is there any changes or modifications that would have to be made to either the boat or controls? Are there other issues that may be a concern? Thanks for any information you have and share.
