Hello, just picked up a Mercury Model KF5 serial number 356434 for $60.00. Not all that familiar with the Merc’s. I would like to know the year of manufacture. Pretty nice shape has some broken fins on lower unit housing. Thanks Bill,
Your coolinng system is different than the later KF5’s The impeller housing should be upgraded to the later motors. Includes o ring housing & cover.
See Fergoson Poole Marine & ask for Joe Poole. He knows all about it & has the new parts.
Thanks all. I ran the Merc engine today. Had the test barrel setup for three other Johnson motors and thought I would give it a shot. It runs very well on gas oil mix shot into carburetor but will not run on it’s own I am sure the carb needs a thorough cleaning and going over. The lower unit housing has some of the fin broke off also the next part up ( the leg )? Would any of these parts be replaced with the impeller housing upgrade? Anybody have some of these parts? Also I ran it on 16 to 1 mix.Is this what it normally takes? Bill,
