I hear that this is a cheap way, $100, to add about 10 hp? The ifo I googled was on cars applications and I'm not sure if those increases apply to Mercruisers. Anyone know of this cheap hop-up?

The belt is $100 all the brackets are way more than that. then you have to have all the pulleys. There has to be a better way to get 10 hp that that. Moral of the story. forget it not worth the trouble.

Thanks, saves me the effort! I really think that it's only 10 hp on car motors, you know with the AC drag?
