I have just bought a 1974 Checkmate 19 with a 150hp evinrude outboard.I have no idea of the age of the engine. <br />Evinrude Model # E235TRLCN <br />(I took this off of the plate on the engine)<br />I would also like to obtain a service manual for it and get some information about the motor<br />. Any help is greatly welcomed!<br />Thanks,<br />Dave
