Prop for an old Sport .20 Hydro.....?

[Bill Gibson]

I built and raced this old boat maybe 15 years ago, and decided to go thru it and run it just for fun and for the life of me a cant remember what prop i ran on it! LOL! The boat is a tad heavy and im running an old K&B 3,5 Drum Rotor engine in it which didnt run bad but its no powerhouse compared to the newer engines........can somebody just get me in the ballpark on a prop choice so i can have some fun!?!

Hey Bill,
With the limited power of the K&B,
Is this Dumas hull heavy?
I would start w/
Octura X437/3
I think there is a Y537/3 (10% more pitch) than the 437.
Or the old standby
X440 X440/3 or M440
Wish we were closer for testing...

I was thinking a 440 or 1440 myself. Rick just beat me to posting it

Hadn't thought about the 437 or Y537/3

I'm thinking the 440 stuff may be too much, never know though??
Don't rule out ABC props either
