You sure? The two usual places to put the details are along the outside of the hub, or stamped into the end.


From memory there are 2 versions of props for that engine - the "standard" K series and one that was sold as something like a "speed" prop (I forget the designation letter - someone like Uncle Al might be able to fill in) but the "speed" prop was essentially a smaller diameter higher pitch blade, the idea being a small, light boat doesn't need so much "grip" so by using a smaller diameter prop, thee was less "prop drag" and so the engine could spin faster, and it was "loaded back up" by upping the pitch for more speed.

Mine had a speed prop on when I got it, and it let go at the slightest provocation (Open throttle, biggish wave......)
