Good morning all,

Can anyone tell me if Johnson lower units have a part # on them somewhere so that you can identify What it came off of? I have a 65ESL73R that has a different waterpump kit than what is suposed to be on it according to the manual and all web diagrams. Im not sure just how to figure it out. If I look up the housing or plate , it tells me that its for a much later model (79-99). That just doesnt sound right. would that much later leg even fit on a 73? Any help would be most apreciated.

Thanks, George

Look in the "Top Secret File", the is an interchange chart there for lower units, it might give you the information you need.
