I've owned this motor since new and was out Sat and noticed the tach was going crazy and it was also not charging (volts remained just over 12 at all speeds). Figured it was a bad rectifier, which I replaced twice over last 31 years. As we were going at about 15 MPH, all of a sudden it felt like we hit a patch of weeds, and when I put it in neutral to check she stalled and I couldn't restart. Prop was clear and after repeated attempts to restart, coast guard offered to tow us to nearest marina. Went home and got fresh gas and battery off my other boat and finally got her started (not easily) and managed to limp home. Bench tested rectifier and although it passed current in one direction and not other per manual for each wire, readings were not the same as the spare I had. So I swapped in the spare and now tach works normal and she charges again, but she still can't rev above 2000 rpms. Besides checking resistance of stator, pulling and checking plugs, checking spark plug wire resistance, checking for spark and all the normal things, does anyone have suggestions. I know I should probably go through the entire troubleshooting flow chart stuff, but the way I figure it, the rectifier may have caused a second problem, or another issue may have caused the rectifier to get damaged, so perhaps I can narrow my search. Thanks for any wisdom anyone can offer, Jim
