High pitched whining sound when first accelerating
 
X15 with a 350 makes a high pitched whining sound when first accelerating. Sound goes away after a few seconds. Is this normal? Yesterday was our first day with our 09 X15, this is also our first mastercraft.

Thanks.

Could be your belt slipping some as you run up the engine.

Also could be your strut bushing.

With the above mentioned the MCX makes kind of like jet engine noise around the 15mph mark. Same happens with my LTR when I start off. I can't recall exactly what makes it, but if I recall correctly its the fuel getting to engine or something of that sort. Perfectly normal.

Mine makes the same noise under load and heavy acceleration. It sounds like a whistling noise.

On my 95 Prostar, last fall, I had the same sound. Replaced the serpentine belt, noise gone. Can't even hear the engine now. Under acceleration, it used to whistle and hum.

Check the temp gauge. Believe it or not my impeller whistles when it's time to be replaced. Gauge will be a bit higher when it's doing it's whistling thing.

Mine is not really a whine,but more of a suction noise.I think its the air intake sucking air. I have the MCX.

My 09 X-15 has done same thing since day 1. No worries.
