    Well I brought this old girl home with me. I couldn’t resist at $100 for boat motor and trailer. The boat I believe is a 1952 Larson 14′ commodore with the wood spray rails. There are virtually no dents anywhere on it and it is complete. The Motor has decent compression and is all there minus the cowling and wiring harness. It does have the original coils in it so obviously they are no good. I haven’t made it to the bottom crank shaft seal yet but I am assuming that that is original as well. The impeller is in tact but one fin is cracking so that will get replaced as well. The pressure tank is in good condition just needs a thorough cleaning and new hoses. The controls on the boat are evinrude simplex and the shifter lever has been poorly repaired at some point so I will need one of those as well.

    For starters does anyone have the parts diagrams for the RDE-17 they are willing to share? I found one online for the RD but not the RDE.
    Also what is the part number for the new coils, impeller, and crank shaft seal?
    Are these motors to be run with 24:1 with plugs gaped at .030 and points at .020?
    What is the flywheel torque?

    Also for the starter on this motor there is no solenoid so I might as well convert it to a 12V system. I found this diagram online and looks to be fairly simple to do but does anyone have a part number for the electric choke solenoid that will withstand 12V?

    Here are some pictures of the boat which is in surprising condition for 66 years old sitting in the elements.


    Thank you all for your help!
