You are right the Donzi and Dauntless boats are similar. I am currently fiberglassing the hull on the Dauntless. I am pulling my hair out trying to find the right motors to make my Dauntless moove out!.. Art at Dumas has suggested 2 AstroFlight 40's Any thoughts??? Where did you get your motors at? I want the boat to plane out and have some real speed. I have also used MACK Products and they are great. I have purchased their running hardware. They suggest using 2 motors per prop but their set up just for motors is $175 X 2 []A bit pricey but I want to make sure I am making the right move. Thanks Marty
