This is a common question asked....
And before I answer I need more information....
How many prop shafts?
What type of battery do u want or can u fit?
How big of a prop are you using? ( this ones vital as bigger props give more load hence require more amps)
Get back to me if you want a few other suggestions.
Although a standard 540 motor on a 15 amp esc will be fine for most props up to 40mm however one alteration to the advice given do not fit a 10 amp fuse between the esc’s positive power and battery, instead fit a 15 amp fuse.
540’s tend to initially draw up to 11 amps when first started so a 10 amp will blow right of the bat when the boat is under load ( put in the water) bench testing with. 10amp will work fine as there is no load on the prop just open air! Be aware.
A 15 amp fuse will be totally fine to help protect the esc as mtronics esc’s have a built in overload and are able to handle a little extra amp just incase ( burst current)
