Re: 1957 Johnson 35 hp - Regular vs. Javelin
The deluxe 30 of 1956 was the Javelin, becoming the Golden Javelin 35 for '57, then the Super Sea Horse for '58. It was in '58 that there were important functional differences between the regular Sea Horse 35 & the Super Sea Horse 35 other than just cosmetics, standard electric start & a starter handle cover. The Super Sea Horse received the new double-walled Super Quiet lower unit that housed a sophisticated cooling system complete with water recirculation path & a thermostat. They also used a fuel pump with non-pressurized fuel tank.
Evinrude's deluxe version of the Big Twin was the Lark, starting with the 30-horse 1956 model)
