Corsair - props
Thanks Daven for posting the cover pic - much appreciated.
As to a reduction box to enable larger props to be used, if you were considering a 120 size 4-stroke engine, the RCV120 swings huge props for its capacity at lower speeds due to its inbuilt reduction gear. For example, a 20 X 12 at 5150 rpm. If that's too much, RCV also have the RCV90 and RCV60 sizes on the same principle. Their new RCV58 size does not have the reduction feature at the propshaft.
If you do decide to go for an RCV, please let us know your experiences with this engine. MalcolmL
