What does it say on top of the injecter pump? (on the round lid) Yours has the earlt 2 piece injecter, What is writtrn on the injecter body can pin the age down even better. The engine is definatell pre 1914, that is when the 1 piece injecter appears. The 2 piece injecter appears as an option on the Detriot Engine Works Marine engines as early as 1904!
Andrew The S/N for the engine should be stamped into the crankshaft, under the brass cap, on the timer side of the engine.
