30' cobra cat w/300 yamaha hpdi 's open fish Has anyone had one of these boats and what did you run for props? The guy has old solid hub merc cleavers on it now and 4 blade bravos slow it down drastically. Any ideas were to start ? Thanks jay.

Call Mazco, they'll get you dialed in. Though not quite the same hull, my thunderboat OB cat with their three blade cleaver saw a 3-5mph gain over the Merc chopper style three blades.
