1974 Mercury 1150 was not charging battery. Replaced stator and rectifier. Old rectifier was rectangle with 3 posts. New rectifier does not fit properly it is much smaller and triangular. Marked bolt hole when I took off the flywheel and am pretty confident flywheel is on properly. Timing should not have been changed. Now boat starts and runs but only idles if I advance the throttle. Tach has never worked before and is now working, but it is reading incorrectly. It will occasionally jump from 1000 to 2000 while engine is at a consistent RPM and is not changing. When I read the volts coming from the stator wires my multimeter starts flashing like a strobe light and the most consistent number I see is 18. If I don't advance the throttle the boat will idle too low and will stall out. Could I have messed up some wiring? Do the yellow wires matter which post they go on? Also, boat has always idled PERFECT until now.... NEVER have I had an issue with idle. Ran great last weekend.
