Prop for 1/8 canard 5660 888kv

[chevelledude]

I have a rc boatworks 1/8 canard with a tp 5660 888kv motor. A 300 amp esc and I want to run it on 10s or 12s battery. Not a race boat but a fun play boat and need to be a fast boat. Any insight as to a prop to start with would help. Thanks Rich

Start at around 50mm on 10s. Test and try different props.
