Losing my mind!!! The engine cover says 65Hp Johnson power shift II on top of the engine cover, it says Loop Charged. I can't find a lable plate on the actual engine. The previous owner gave me a hand written piece of paper with 1968 Johnson J3845008. The reason I am loosing my mind is that I purchased a manual for a 1968 65hp johnson and upon recieving the service manual, my engine does not resemble anything within the context of the manual. It talks about a 2 cylinder engine when mine has 3. Someone help me please!! Desprite for answers.

Just a guess here RC....maybe a 70' 60hp. Most likely a looper. If you can't find the model number on the transom bracket, look on the engine block for a large welch plug. The model number will be on there.

Yep! 65hp 1973. It's a Johnson. Manual shift, long shaft Looper......current recommended spark plug is a Champion L77JC4 set at .030. Fuel mix is 50:1.
