6.5 Kohler starting problem

[300 Ray]

Hey Guys, A friend at the marina just purchased a 99 Regal 32 with a Kohler 6.5 Genset. Engine Starts/Stalls. Gen has 200 or so hours on it. I'm assuming it's either the temp switch or the oil pressure switch. Any thoughts would be greatly appreciated. I have had a heck of a time finding any schematics on-line. Thanks Dan

I have to hold my start switch down for a few seconds after it starts.
