Yamaha 90 Cutting Out
Had the small boat out over the weekend (Ribcraft 5.85 with a Yam 90 2 stroke). As a bit of background, this boat has always seemed a little under powered / over-propped as with a decent load of divers and kit on board, we only get 4400 at WOT and approx 25 knts.
Anyway, 3 or 4 times over the weekend, the engine cut out whilst running flat out at full throttle. The cut out was instantaneous, no spluttering, as if someone had thrown a swith (so suspect electrical). Fortunately, and slightly oddly, the the engine would start back up and run completely normally as soon as the ignition switch was turned, making a diagnosis of the problem difficult.
Anyone had anything like this before?
