    Mercruiser 3.0 only stays running with key engaged?

    Went from electronic to points ignition, are you using the 1999 harness or the older motor harness Just get a ballast resistor which would read 1.8 to 5 ohms. This will provide the coil with 9V when running

    Mercruiser 350 poor performance

    The Reg is behind the motor mount on top. My guess is you have a 30 psi system. Could try to pinch closed the return fuel line going back to the filter. Do this without the motor running just cycle the key. What your looking for is to find out if you can get the pressure to go up to 50 psi...

    Delco voyager conversion

    That's good Then just the one connection between Dizzy and coil. Then just needs power from purple to run. The other connection on the coil would be for the Tach but its not needed to run

    Vacuum Gauge Connection

    Thanks I understand The big IF unless someone has an answer is to find a plug on the intake. If there is one on one of the intake runners then plug can be removed and fitting installed. If not, then its of no use. Could use a Tach but agree not as good for idle as a vacuum gauge

    Delco voyager conversion

    It has a connector between Dizzy and coil If you have an Alpha drive there should be a wire between the right connector on the Dizzy to the shift interruptor The Dizzy module gets power power from the purple wire which use to feed the TBV.

    I don't know either. If your on a hose, then the motor is not getting all the water it can. If your in the water and it still gets that hot, I just don't know
