I was running my 87 Bayliner with a cobra outdrive and a Chevy 350 big block engine.
I was just putting along until I got past the bridge and we’re aloud to go fast so I took throttle down to almost full speed and the nose of boat raised up then engine shut off on my. When I went to start it it wouldn’t start and now makes like a buzzing sound and or clicking noise. And the battery meter now bounces just above 10volts but it usually stayed in the middle around 13-15volts tried a jump didn’t work charged battery didn’t work filled up with gas prior so I know it’s full has new distributor cap and wires and plugs it does sound like starter does try to start but can’t think of anything else to try for engine was thinking it’s electrical issue does anyone have any idea or tips for me thanks!

Check all the Connections, Connectors and Wires for tightness, and signs of Corrosion

Is the engine turning over?

Safety lanyard would be the first thing that comes to mind. Second would be fuel pump.

I thought maybe it was the lanyard safety switch, but mine will still crank when the switch is tripped, it just wont start. Mine is a 4.3 Mercruiser. Maybe others are different?

It sounded like it was a sudden thing. Like something disconnected abruptly. Could you have hit the lanyard switch accidentally?

Are all battery connections tight?

The Man Overboard Switch is to kill the Ignition, not disable the Starter

10 volts is a dead battery, too dead to keep ignition.

Remember, a battery at 12 volts is dead. my guess your alternator died or something else happened, and you kept running

It would not make much sense to disable a Starter, if the Skipper is tossed overboard...

There are interlocks to prevent power getting to the Starter if the Engine is not in Neutral.
