is it forwards only? in which case it will be looking for throttle at the lowest position (not centred)

OK ignore my last comment  :D


Silly question time
1... have you tested the receiver and confirmed both channels are working?
2... Drive battery (or RX battery pack) is fully charged


Don't have much experience with that particular ESC, but when I did a quick google search I found out that at least one member on here had one and was discussing it on another forum.  So they may be able to help


I have dropped said member a message alerting them to this thread

that esc needs a seperate bec, sorry if you already know this, but what that means is it needs a seperate power source to power the rx, and then the esc, so plug it into channel 2 (throttle) and you need 4 x aa batteries (6v is a safe working voltage) into the rx in "batt" slot. Always ensure the voltage is good, dont leave connected, if it drains away whilst in use you could lose the signal and your boat will become uncontrollable %%  a cheap voltabe guage plugged into AUX in the rx will be a visula monitor of rx battery supply condition.
 
The seasprint also needs 6 cells minimum, I used it a lot some time ago, its a good esc, not water proof though so stick it in a plastic box of some sort for extra protection

If its a 2Ch receiver you can use a servo Y lead to connect the voltage meter to one of the 2 channels

Plug a servo into the slot intended for the ESC.  If the servo waggles in sympathy with the TX stick, the radio bits are OK and the ESC needs a fettle.  If it doesn't the problem is with the radio part.  Or the power to the control half of the ESC.
ESCs of that era usually had a pair of adjustment pots accessed via holes in the case.  One for centre, one for range.  Adjusting them was a finger and thumb job with a small insulated bit of sharpened plastic* rather than a good run at it with a bayonette.  I have had cause to repair one or two (similar age) ESCs where replacing the mangled bits of ruination was all that was needed to fix the damage done by "a previous owner".
