Hello, I'd like the opinion of some of the experts on this site concerning the following. I own a 14' Jon boat, with a 15" transom. I have an opportunity to buy a practically new out board (Honda 15 HP), but it is a 20" or long shaft. Can I replace the lower unit to make it a 15" shaft? If so, how costly would that be? Do I have any other options, or should I just forget it, and look for something with a 15" shaft. Thanks again, looking forward to some replies here.
