Hard Landing Kills Motor ?
Was out running yesterday, it was a little bumpy and I was real loose and sure enough found one of those out of nowhere oh **** waves and launched it big. Landed hard, was applying throttle for reentry and everyone is getting thrown forward. The engine cut out upon landing.
Tried starting the motor, turning over just fine but not firing. After three or four times with giving it gas, started just fine ran just fine no more problems. My question is what happened ? I had 3/4 of a tank of gas so I know the rough conditions wouldn't affect the fuel jumping in the tank. Tell me what you think.
Dano,

If it's an EFI or computer-controlled engine, a hard landing can sometimes trigger the low oil pressure switch, and cause the engine to go into "slow" mode, or even shut itself off. If this is done by cutting the fuel, it will be hard to restart until the intake tract is wetted down with fuel again. Sometimes, this can be cured by re-mounting the oil pressure switch or sensor on a 90 degree elbow so that it is horizontal instead of vertical. That way, a vertical impact is less likely to set it off.
If you're carbuerated, I will defer to the carb experts.
The other possibility is a bad electrical connection in the ignition or battery circuits. Don't forget to check your killswitch lanyard switch. (You DO have one, don't you?)

I had the same problem. When the boat landed the engiine would cut out. It was gradually getting worse to the point that I didn't know if I was going to make it back to port. Turned out the battery cable was working it's self loose. The bumps were just enough to cause the ignition to cut out for a moment. Not saying that some carb slosh wouldn't be the problem-it certainly sounds like you flooded the engine, but maybe my experience is something else to look into.

Sorry, I was in a meeting for the last few hours.
It is carburated, the floats getting stuck was a suggestion at the dock. I did check all electrical connections and they seemed to be good.
This was the first time this has happened since I have owned the boat. 3 years. However it's not the first hard landing. Should I just hold tight to see if problem persist or should I do something now ?
