That's true Bob a divers do change props. Should be cheaper than a boat yard haul out too. Still without hard data finding the best prop for our EP boats is an expensive experiment. We really need an app to help fine tune the specs, We had a saying in the shop. "If you can't make it better, don't make it worse" :)

Hi Mike,

The diver who cleans my bottom (a very experienced sailor) claims he can change a prop in the water. I might take him up on that sometime but I'll want to do the first prop change myself with the boat on the hard - which would be in a few months as Ox is in need of a bottom job - which presently can't be done in the water. :-)

As Myles mentioned cost is a big factor in experimenting with props. Some boats more than others. Much easier to do with an outboard or trailerable boat. But, on a 30 foot sailboat like mine it becomes a much expensive process. Right now the boat is on land for the winter so changing the prop would be pretty easy. Though I'd have to wait until spring to check the results. If it turns out to be a mistake and I want to go back to the original prop it would cost another several hundred dollar just to get the boat pulled by the boat yard. Which is why without seeing more definitive data I am reluctant to experiment with a new prop. Since my original prop is working well I remain in a "if ain't broke don't fix it " frame of mind. Still I would love to have an idea of what prop specs might improve things should it need to be replaced.
