really strange, first time I've ever noticed this
when i turn the key, it will crank briefly and stop as the key actually makes a full revolution (flipping upside down)
it will flip, in full revolutions, over and over
when it does flip the cranking discontinues

to get the boat to start i have to turn the key just barely... too far and it flips upside down

anyone ever had this happen before?? possible reasons why?

sounds like your ignition switch, tumblers, are flat wore out, time to replace your ignition switch...

is that a dealer only part or something I can get at napa/etc?

Auto parts or someplace like west marine should have something that will work...

Depending on your boat you should be able to replace it with an ignition switch made by Sierra part number MP41040 - just used this in my boat. Works great.
