Hi all

As mentioned in another thread, the last time I had a boat on the water, the speed controller was a coiled tube and pivoting arm, operated via the servo. Now it seems everything is electronic and there are dozens of different ones.

So far I have found proper water proof boat ones, which’s seems appropriate, but as for the rest they quote all different amps, number of cells I’m getting a tad confused looking for a suitable unit.

So the motor is a Graupner Speed 900bb torque running off a 12v sealed lead acid battery. Quite a hefty motor, but then the boat is quite large, so I decided to go bigger prop run off a slower rev’ing more powerful motor. It’s not s speed boat, it’s a sort of cabin cruiser, so its more just to have fun with than zoom about.

Any suggestions would be hugely appreciated.
