Help with Mercruiser!!

Last weekend we were skiing behind the family Tige 20V. After a few sets it would not start for a while, then a strange noise (almost a pop). The engine started with a puff of black smoke.

The engine then ran with a strange whine to it. It performed fine, all the gages looked normal. Did something really bad happen? should I quit driving it??

What Happened? Thanks

I would have the fuel pressure checked...the high pressure pump may be making the whining noise, and may be on it's way out.

I second the fuel pump but also you need to check for any vacume leeks. They will whine when not attached and will cause hard starts

The engine starts fine now, It just has the noise.

Thanks for the help!
