Hi Movinon - you might want to post this in the V-drive section, as there are many Rayson Craft 'experts' in that section. Also, if you are in the PNW(Pacific North West), check in with Frank DeFir out of Portland. He has several of the Rayson Craft molds. I've talked to him over the phone before. Nice guy and no attitude, which is a relief in this industry. (I can say the same for Carson Brummett out of Brummett Marine - really cool guy and helpful). Hope that this helps. Name of your builder that passed away, Rudy Ramos - a legend among the GN racing crowd. Also build one hell of a ski racing boat (21') that was used extensively on the circuit back in the 80's.
