Motor 'stutter'

Hi guys,

Can anyone help with this problem...
My motors (both) 'stutter' when on the water, i.e. they speed-up and slow down as if the trottle is being opened and closed very quickly. This does not happen when on the bench.

Motors - matched pair of 540 type with 3, 1uf (one microfarad) capacitors each, one between terminals and one from each terminal to case. Running at 12 volts and drawing 1.5 amps each at full throttle under load.
ESCs - Mtronic Viper 15 (pair)
Layout - (see picture) ESCs are behind battery (under it in photo) between motors. Receiver is to the right of the battery on the coaming. Aerial is routed (up) along coaming, across stern (top of pic) and then down on opposite side. Receiver has been replaced as I thought this was causing the problem, BEC's have been disconnected and battery pack installed. Only one servo lead runs anywhere near the aerial.

Has anyone had a similar problem? What was the solution?
Any help or suggestions would be appreciated.

TIA,

Scottie.
