I have a 1996 150 hp Yamaha, I can get the serial number but don't have it with me.
The black oil is coming out of the prop exhuast with the water. I just installed new plugs and fuel filter. I haven't ran the motor in about four months. All of the work has been done buy a certified Yahama Mechanic who if very good.
I am running it on a hose just to rinse the engine. I haven't had it in the water running.
Trying to get everything in order to start fishing.
I didn't put any fogging oil in for storage I would run the motor when I couldnt take it out.
Due to Hurraine Ike I wasn't able to run it for 4 months. I have never had oil come out of the prop exhuast before. The motor is running very well. Serial # XXXXX
There was about a cup of oil come out of the prop exhuast. Do you still think it ok?
