RC boat starts slow then takes off

[vfrman40]

Buddy of mine has a RC boat,,,give it throttle and it goes so slow then all of a sudden it takes off. Check flex shaft and all. Boat is electric. Any suggestions.

sometimes that is normal.

Sounds normal. The prop cavitates and then catches up. What prop? Have you tried other props?

The ESC may be set at soft start.
