Hi all,<br /><br />i have a 2003 60 hp fourstroke with carburettors that has begun to surge at around the 3800-4200 rpm range. Above and below this range the motor seems not to surge. Any suggestions??. The motor has done about 40 hours work and has had its 20 hr service.<br /><br />Regards<br /><br />Kellaig
