Trouble starting, 1996 super sport

[J10]

When it sits over night and I hit the key, nothing (no turn over, just nothing). I wiggle the throttle and make sure the safety switch is in. But after a few times of this then it starts right up. But then out on the water after running, no problem. I hit the key and it fires up. Any clue???? Could there be a loose connection on the ignition?

My guess would be starter relay/solenoid. If you lift the engine hatch do you hear a click when it won't turn over? Other things it could be is the neutral safety switch is wearing out and it doesn't think the boat is in neutral even though it is. Another thing to check is to make sure that all power and ground connections are clean of rust and tight.
