Yamaha 200 Vmax
Having messed around in various types of water in various types of boats, I decided to take the plunge and buy a Valiant Rib with a 200 V max early this year.
The engine has now developed a problem at Idle, whereby the revs drop to approx 500 and the engine appears to 'sneeze' and then stall. There appears to be no problem at the higher revs and I have lost no power / acceleration. All gaskets have been changed, Carbs stripped and cleaned and timing checked correct. After each 'sneeze' the engine starts perfectly well.
Any ideas as to the cause - severely scratching head now!
