Something is wrong with the circuit. #2 wire should be more than
adequate. Vans supplies #2 for connection battery to master relay,
master relay to starter relay and starter relay to starter. My Mooney
has the battery behind the baggage compartment with same #2 wire. Same
length run. Took me some work to eliminate all high resistance
connections, but once I got all connections clean, air tight, the
performance issues went away. I do have a PM starter and they have HUGE
current draws compared to other design starters. The Skytec trouble
shooting chart is good for determining where the problem originates.
If there is too much voltage drop in that one cable there is a problem
with the connection at one end or the other or in the ground return. #2
will carry the current needed without excessive voltage drop. You have
to ensure there are good tight crimped connectors and tight connections.
I suppose you could have a relay with excessive voltage drop.

We are getting too much voltage drop with that long #2 wire and should be running #1 or 0. The lycoming supplied starter would work fine then.
