Hi guys! First time on the thread. Bought a 1963 Elgin 12' yesterday, with a 4hp Mariner motor. Motor needs a prop. Can someone recommend a prop and where I might be able to find one? Also, is this a reliable motor? It started, but I did not run it for any period of time.What should I have done to it from a maintenance and tune up point of view before I use it in the spring? One last question, I could only find a 4MA L on line when looking up serial numbers. What year and kind of motor do I have.....does the L mean long shaft? Thanks, I appreciate your help....I'm new to all of this.
