After I posted I thought who purchased the props. But if the owner gave erroneous data to the yard and the yard ordered the props and that led to the messed up “sizing” then where are we now? If I was the boat owner and gave them inaccurate performance data I would suffer the consequences. I am far from Jesus, Muhammad, et al and keenly aware of my shortcomings but dishonesty and laziness are not among them. That being said I cracked the case on a ZF transmission a couple of years ago. And they no longer made the gears which led me to changing both. An expensive proposition. I was amazed at the number of people who encouraged me to say I ran aground and give it to the insurance company. I did not.
