New to this please bare with me. This 1964 40 horse is spotless. It turns over and runs, thats not the problem. At Idle she runs a little rough, she has sat for two years, any suggestions?? Also I got this boat litterally in pieces everything works great. Volt gauge and Hot motor light works fine. Ignition works great also. What my concern here is the prop seems loose?? any suggestions on that.<br /> Next question this is a electric shift setup, after rebuilding the electrical box were the starter switch and voltage regulator is, I still have 4 wires left. <br /> 1 is black,, ground??,, 1 is green goes all the way up to under the dash board havent traced it yet?? next two look like they are attached to the stereo, which is easy enough. any help on this old girl would be appreciated, and if possible and wiring diagrams would be great. Thankyou
