Your boat was originally purchased new by Dick Sharp\Bryant Corporation out of Seattle WA. It is a 1969\70. I was crewing for my uncle's during that era and saw it run at all the local races that season until it blew over and broke Dick's leg. He continued to run it the next season until teaming up on a new boat for the 1972 season. That boat used an Evinrude as the Bryant Corp was the OMC distributor I believe (I was 15 so I'm dusting the cobb webs off).
