Building a 7'6" Crackerbox
Hi guys, I am building a huge 7'6" Crackerbox wooden boat from a blown up Dumas plans. It will be fairly light. The issue that I am having is the engine and prop set up I will need. I know that there is some large engine out there like the clone Blata, the converted zenoah G62 and more. What is the biggest prop that can adapt to a 1/4" shaft? If anybody can help, I would appreciate it.
Thanks Dave
