RE: Robbe Prinzess Boat & Roqua Outboard
Funny you should mention a smaller prop. I have another prop for it - the one that came with it when I bought it off eBay in December. It had a small chunk out of one blade and I thought about trimming it down, making a template and trimming the other blade to match. This would cut down the blade area a bit and should result in increased RPM. If memory serves, the original prop on the Roqua was 55mm in diamter. Not sure of the pitch, but I have it written down somewhere. Might have to get one of the adapters to run 4MM props to try some others...
