Battery switch or keyed ignition switch
Today as usual boat started fine, went thirty minutes out in the bay shut it off. Spent around two hours in great conditions. Storm coming up so I tried to start the engine. As usual nothing, went below to flip battery switch ( this always works) but now nothing. Flip back and forth nothing. Check battteries both fine. Got juice to the ignition switch, still nothing. this consistently happens but only after an hour or two of sailing. For instance it never fails in the marina, if I go to fuel dock it will start up. Only after it sits for an hour or so do I have a problem. Today it finally started after an hour of panicking( bad storm coming up).

When I turned the key I got silence, I had a multimeter on the switch. I have a 79 Columbia 8.7

OK, first things first. Same test except put the test leads between ground and the S terminal on the keyswitch instead of the I and turn the key to Start. 12V yes or no?
No = bad keyswitch Yes = repeat the test with the tester on the starter solenoid small post with the white wire attached. 12V yes or no? No = wiring harness issue Yes = bad ground to engine or bad starter solenoid On principle all battery cables should be tightened at both ends, positives and negatives. Pay special attention to the battery switch. The mention that manipulating it remedied the problem previously suggests a loose connection there.
