Ok here we go..got to marina and switched port switch Carling VMDJ (good) for starboard switch, (suspect bad). Bingo....switch worked. Replaced with a VMDA that was available. Now fixed. Down side is the new switch light is reversed and not green to match the rest. Will be looking for a VMDJ now. Thanks for all the troubleshooting suggestions. They were all excellent. Neutral switch, of course grounds.....checked them all. Thanks again as now I am back on the lake!

BTW I had replaced the solonoid and apparently it's good....put in the emergency spares box .

When pressing rocker start switch on our 2004 320 signal sounds, fuel pump runs, then when pressing to start does not start till about 10 tries. Any suggestions on where to begin?

It is not the starter switch, it is the slave solenoid. This is a common failure with Mercruisers.

This may or may not be your exact part number, so look it up.

+1 for the switch, although over the years sometimes it was the solenoid. I carry both spares. Don't overlook the wires and their connectors behind the switch too. It's all about having enough current to pull in the solenoid contacts, or having enough current to overcome a sticking contact. Two problems, same effect.
