    I'm trying to learn more about Hydrodyne's construction process for their tournament inboards that they started producing in 1991. Supposedly their construction process used something they called Hydro-core which added something to the lay-up process in the hull, adding strength. A process used in offshore racing boat hulls, but I can't find anything about it. Any help or guidance to other sources that might have history would be appreciated. As Hydrodyne made these boats for 5-6 years I'm expecting someone has information on how they were built. I actually have an old video promotion that includes factory footage that again talks about the process. Any help appreciated!

    It's definately wood construction with a heavy duty beam and twin skags. My brother bought this '71 from Carlsbad Boat and Ski Club back in '73. It has a 318 Chrysler Marine engine and a Volva 270 outdrive. It's rated at 225 hp. I had the ignition changed to electronic; I got tired of resetting the points all the time. It's now at my nephews house in Murietta if you are interested in it. Runs perfectly and has the perfect prop that my brother knew about. When you are tacking 3 grand you are going 30 mph.
