Michael,With a traditional diesel engine, its kind of all or nothing. Typically you are either sailing or motoring. Motors sailing is an option but generally not an enjoyable one.With electric you will find yourself almost almost always motor sailing. Lets face it, the wind is usually not quite as strong we would like. If you want to make your prop "invisible" it doesn't take much power at all. If you want to add a little speed, help point higher and get you through lulls, it takes just a little more power.For those reasons, I recommend going with the most efficient prop you regardless of drag. This way you will have the more range when needed and still have the option of no drag by adding a few watts into the system.Matt FoleySunlight ConversionsPerpetual Energy, LLC201-914-0466On Saturday, January 9, 2021, 09:04:25 PM EST, Carsten via groups.io <carstensemail=yahoo.com@groups.io> wrote:Michael, consider a big folding or feathering prop, which will give you far less drag.Then find the proper ratio for engine rpm and prop rpm.A toothbelt solution will give you the opportunity to change the ratio.On Sunday, 10 January 2021, 04:29:08 GMT+8, Michael Blackstock <mdblackstock@gmail.com> wrote:Thanks for your responses, all. I think I'm just going to go with another stock 2 blade to reduce drag under sail. I plan on utilizing the motor very infrequently, so more speed under sail sounds good to me.There are so many resources for Catalina owners, but I thought I would check with you all first.I will definitely be chiming back in when I begin my motor and battery install!ThanksMichael Blackstock
