OK, I moved the ground wire from the solenoid directly to the mount on the engine case, and connected the original ground there as well.
I removed the old 3 plug connector from solenoid and harness and installed new spade connectors on the white pull in wire and the purple hold in wire. Cleaned and checked connectors on aux mag end and lubed and tightened. Checked resistance of pull in wire and it showed no resistance.
Cranked right up. Warmed up engines and let sit to heat soak and recranked ok.
Haven’t been able to take boat out for extended run yet.

I’m out of town for several days so can’t get at it yet.
I did check the solenoid before installing it and it retracted when power was applied to white wire. I will switch the ground to the mounting tab on engine and am going to install new #12 wire and connectors from mag switch to solenoid. I felt it was a voltage drop problem but didn’t know what the aux mag switch did.
Will report back when I get back.

Thx

Here are photos of my setup. The solenoid does not have any linkages to adjust. Strictly a retract, holdin and extend to shut the fuel off. I had one spare solenoid that I installed and it did not retract, so since it came with the boat and I couldn’t verify that it worked properly, I replaced it with a new one. Same results. Won’t retract on hot start, but holds in run (retracted) position until ignition switch off. I can just barely assist it to retract and it works.
The second photo is what I believe to be called the AUX MAG switch, located just under the starter. The large white wire coming off the top stud goes to the center prong on the solenoid switch, which according to my schematic is the retract wire on the solenoid.
The engine is a 6BTA 5.9 M2
S/N 60237043

Hope these help..
Thx
It appears the photo of the switch loaded upside down. The metal bracket should appear on top.
