'99 Prostar noise in reverse

I just picked up a '99 Prostar straight drive and finally got it on the water. It runs great, but makes a noise in reverse that sounds like an electric winch. No noise going forward, just reverse. I called the guy I bought it from and he said it's always been like that, but I should have it checked for my peace of mind. Sorry if this has been addressed before, I looked around and didn't see anything on it. Thanks.

Thanks. Why does it whine like that. I had an older MC and it didn't. Just curious thanks again.

The noise probably comes from the idler gear in the transmission that comes into play to turn the prop in the other direction. The idler gear may have straight cut teeth which are inherently noisier than helical cut teeth. Many cars whine in reverse for the same reason. Wouldn't worry about it.
