How can anybody can tell its a model “F from those views? Thats a rather grand assumption. You’re just guessing, not proving. I can already tell its not a model “F” flywheel from the thickness as well as the spark plug hole angles. On an “F”, both spark plugs would be pointing straight ahead. This one has the port spark plug pointing upward.
Please provide photos of the topside of the flywheel, the back of the motor where the rudder connects to the steering bar, and the lower unit and rudder themselves. How the water tubes are formed (straight or spiralled) also are a tell. All of thosewill provide clues as to a rough identity WRT model year. If you don’t have the gas tank with the Elto ID plate on it, pinning down an exact model or vintage will be tough.
Here are some views of model “F” motors, note the spark plug angles and flat rudder with water pump in front of the steering bar.
