i have 20 hours on this 09 model year. this time after putting it in the fresh water flushing tank and upon starting there was quite a bit of blue smoke for just a moment and then none. then noticed an oily film and tan colored globules about size of a dime floating on surface water of tank. the motor ran fine for the 5 minutes in tank. after stopping i took sample from tank surface and it was greasy and grey in color. the motor oil showed the usual reddish-gold color so i am thinking that this grey oil may be from the lower unit. after a day inspected the motor and leg and there was no sign of leakage. Also concerned about a relationship to the one time blue smoke. the motor had been laying previously on side but done so by the manufacturers recomendation. also, run in salt water previously. Ideas?
