Re: prop
I had the same experience as Junior. The CompProp 4 blade 23 flexed so much on my boat, that it ran about the same as my 19 aluminum. Used it for skiing on a 175 Evinrude. Annually, one of the blade tips would fall off-the separation point showed an inclusion in the casting. I sent 3 of them back to the factory and they were replaced free due to the mfg'g defect. After the 3rd new one came back I sold it. Look for another type prop.
