rpm increase and decrease w/o adjusting throttle
Yesterday I noticed the engine rpm increase for several seconds, then return to its previous rpm without touching the throttle. It seemed to irregularly cycle. We're talking several seconds, then normal, then several seconds. There is no discernable change in hull speed when it revs higher (perhaps 200-300 rpm). Clutch/reversing gear problem? This occured on the way back in after a 3 hour sail. No similar problem previously. Engine otherwise is running well at present.
