2.5 HP Yamaha 4 stroke outboard problem

[tlacombe97]

Motor starts first crank, idles 5-10 minutes then stalls and dumps oil. Motor starts up right away and does the same thing.
Any ideas?

What does dump oil mean?

What does dump oil mean?

It stalls out and then oil ends up in the engine housing and empties out the drain hole at the bottom. No leaks prior to stalling

 

[boscoe]

From where is the oil exiting the block?

 

[tlacombe97]

Can't see that. Too much in the way. Is it possible the oil is too full?

Could be too much oil or could be oil diluted with gasoline.

Drain and refill with the correct amount of oil. Clean up the oil mess. Start the motor and observe it to see what happens.

Thanks, once I get the boat back from upholsterer I will check it out.

Started the motor this weekend and it hasn't done it again. Did it about 5 times last a week ago. Go figure.
