Hey guys, i'm a mercury guy so i dont know alot about Johnsons. But my neighbor gave me a boat and trailor with a Johnson Electramatic Super Seahorse 40HP. <br /><br />The Model # is RK-24 and the serial # is 342874.<br /><br />What year is it? <br /><br />And, are there supposed to be 2 gaskets for the water pump? The lower end was apart when i got the boat and there is only the one metal gasket? <br /><br />Thanks!
