Hello j22mdr. What a great sight to see a Wavemaster from the 50's. We here in so Calif. had the plasuer to have one of countryman that had a very fine hobby shop, stocked with many of countrys kits airplanes, engines and boats. The Wavemaster,Sea commander, Sea Queen were very popular. Electric in 50's and 60's was not very popular. Untill Al Wood broght the Taplin Twin to us and Gannet we converted airplane engines to water cooled. We had some pepole that were quite inventive I E making single channel radio work a rudder and a throttle high or low speed. I have continued to build Boats and planes but as I get older I like the brain work that has to go into boat building. Going though 55 yr's of plans I found a set of Wavemaster plans and templets, So I'm building 2 one for electric the other for a O S 61 4 cycle converted to water cool and to ignition. Some day when I learn how to post pictures I will post some, to old to slow to learn this modern age. Reards Red.
