"Hi Guys,

I have a problem


"Hi Guys,

I have a problem that's giving me fits.
92 four winns w/7.4L omc ad spitfire ignition.

The boat usually runs great, but occasionally it will seem like it's running on 6 over 2k rpms. It always starts great, but when it's running rough, (doesn't matter if it's under a load) it will overheat slightly to about 205. Sometimes it will clear up if I let it sit, and sometimes I have to limp it back to the dock and take it home.
Fuel delivery seems good and all of the fuel components have been thoroughly checked and pressure is good.
It would seem that it is electrical, but I'm not sure where to look first.

Thanks for your help and expertise.

Timing?....... I dont consider 205 much to worry about. My little V6 seems to heat hotter than the "supposed" 165 Thermostat in it. I just ran it till it opened, (new thermostat) hot or not. Voltage regulator? Im guessing, as I'm no expert. Just things I've come across.
Good Luck.
