Thanks for your suggestion before the surging started I would just drive the boat as a constant speed did not matter so I did not notcie the surge so much now the speed has to be constant I have to try and control it as precise as I can , you go to 10 knots but it keeps going up, not in high revs then you just throttle e touch and it drops of to 5 knots then you have to throttle up again.

Anthony"
