Re: Plastic Prop???

I'd heard of one from Oz, probably the Kiwi, years ago. At that time it was not CF but was an engineered resin. The idea being that the amount of curve in the blades SHOULD NOT be the same at all speeds, and by using a slightly flexible blade (plastic) you can actually build a prop that changes curve to work better as the prop speed increases.

At the time they were supposed to be a novel idea and a good thing. I think PS tested them out, coupla decades ago.

Bit of a thread hijack here, but yeah, it's a big engine for a 28. A slightly tubby, 28 maybe. I can tell you that here on the Great Lakes, it's nice having that extra punch. We'll often go up the Lake Michigan coast for a few days, and on the way home we're going straight into 5-6 foot, steep Lake Michigan waves. In those situations, it does not seem like we're overpowered.

One might assume that Catalina had these engines on the shelf for their other models, and it was simpler to stuff it into the 28.
