Need a JG I25X prop to run on an old .40 Cobra (FG round nose sport 40) made in1991, similar to the Lil Hoss. I remember it ran best with a JG I25X prop. Anyone know what would be a good replacement (Octura,ABC,Grim).
 
I, too, like the JG I-25 and I-25X props. I ran them back in the 70's and 80's. Up till a few years ago they are still available from Dumas.

I am no prop expert. But for a sport 40, I use X-447, 448 and 450

I'm surprised you're not looking for an old Futaba brown box 2-channel with the gun handle trigger system.

Mele Kalikimaka Jerry...

No brown box, using an Orbit single stick! Like Francis King......

Boat has a K&B disc rotor with Gardner exhaust throttle.

Tried the Octura 400 series prop. Not enough lift. Like to see daylight under the boat!

Have a Happy New Year!

I have 25X, I25X(it's look little pitched on cups), J30 and 3J31

you can check the pitch using a propchart

Thanks Roman. Had lost my JG prop chart. Have lots of I25, so I can modify those...

Thanks everyone,

Happy and safe Holidays
