what prop should I start with?

[DeltaForceMan]

Here's my setup.. 38.5 inch delta force mono hull, 1527 neu castle 1250 kv motor, 240 a swordfish esc. I will be running mainly 6s 2p most of the time but will also run 8s 2p occasionally. Thanks for any info!

Start with an x455/3, on 6S that should get you mid-50s if the boat is set up right without excessive amp draw. On 8s start with an x450 or x452.

Sweet, thanks Fluid.. what's the difference between 2 blade prop and a 3 blade performance wise?
