John,
Been down this road on a couple of boats with Yanmars. Likely problem areas,
poor connection or connector on the positive wire from the starter switch, poor
connection in the harness connector, poor connection or connector at the
solenoid. Same for all negative wires.
First, make sure you're getting a reliable 12 volts to the input of the
ignition switch.
If so, I would first replace the connector on the positive wire on the starter
switch. Use a marine grade connector and coat both the connection and
connector with USS TefGel and re-attach.
If that doesn't fix it, test the switch several times with an ohmmeter. It
should work immediately each try. If it doesn't replace it.
Next, pull the engine harness connector apart, spray it with Boeshield T-9 (not
WD-40), push it back together and pull it apart several times. See how that
works. If it works, pull it apart, coat the connections with USS TefGel, put
it back together and tape the mating surfaces.
Next, replace the connector on the positive wire at the solenoid.
The above steps have fixed intermittent starter problems on at least two Yanmar
powered boats I've worked on.
