Bravo Nosecones
 
How much do nosecones typically gain you on a standard bravo lower w/ a fairly high x-dimension? Just looking for a ballpark here, is it worth it?

My bobs cones are good for about 2mph running around 90mph with a 4.5" shaft depths on a straight twin engine vee.

I put a Hydro-Motive on mine, I gained more in drive-ability than anything. I would definitely do it again. I'm still testing props so I don't know how much I gained, but it was worth at least 2.

After installing Imco's cones ... props didn't blow out anymore @ high speeds. Also helped with stability ... didn't notice any speed gain . Prop shafts @ 5.75 inches below running surface .
