NO !!! I haven't put a 52 in the Beaver, mine both have 46's and I like the OS best. I talked with a fellow that was going to put a 52 in his but never heard how it turned out. If it will fit the mount and go inside the cowl I think it would be Great, if I wasn't so lazy I might try it but mine are both flying good and you know the old saying " if it works -- don't fix it !!! "

On my Cessna with a 4 cyl I went to a 3 bladed prop to give me more clearence from the floats and I think it pulls a little better then a 2 bladed which might be something to try if you go with the 52. In the past I have found that I don't care for 3 bladed props on the smaller engines but the 52 and up are probably fine.

If you decide to try the 52 I would like to know how it worked out, I have an extra one that just might need a new home.
ENJOY !!! RED
