My good friends 28 with 300X's run 121 (GPS) using 15 x34 three blades. Not familar with Dewald props. I would assume the older X motors are faster than the XS simply because they turn more rpm. The Merc four blades for outboards are not a top end prop at least on three cats I tried them on. With 250XS motors that boat should be over 100 mph. Outboards are finicky when it comes to props and setup. Once you nail it leave it alone. I have spent many many hours making little changes to dial in outboard cats. Shaun Torrente is a very knowledable guy on Skater setups.

That's a very unique looking prop. How long have they been in production and how many 28 to 30' cats do they have them on. I'm certainly not an engineer but that looks like a lot of metal spinning on those blades. With the sharp angle on the leading edge at the hub it seems like a lot of stress would be generated and lead to failures. That being said if it and the lower unit held together it looks like the blade would generation a lot of forward thrust. But then I could be wrong!
