What changed, likely the batteries are aging and not putting out the voltage they used to under load. Lower voltage, higher amperage. You need a solenoid that can handle the amperage. I wonder if changing to a 24v starting system would be easier?

Just out of curiosity, can you put a dc amp clamp on the cables and see what kind of amps you are pulling?

There you have it, a separate battery to run solenoids that will not be dragged down by cranking.
You will have to go back to that third battery, and can still have your on boards.

The solenoids are energized by the third battery now. I have tried running the solenoids of of one of the starter batteries and currently have them running off the third battery and it didn't seem to make any difference. Granted I have never tested the third battery and 3 fuel pumps and 3 ign systems might be taking it down too much. I can test that with out too much problem with it sitting the way it is.

Tech guys really frown on that. Has crossed my mind tho. For some silly reason they want this thing to only start in neutral

Why not go to a pneumatic starter system like tractor trailers use now.

I haven't seen an air starter on anything on road with a build date after 1972.

That may be, but like 90% of the engines that we used offshore were air start, and they sure do work well as long as you have enough air.
