2000 Mercury 50HP Outboard Problem

[egavas4]

I have a 2000 Mercury 50HP 3 cyl 2-Stroke Outboard, The problem I am having and can't seem to figure out is when I put oil in the engine mounted oil tank. After a day or so, I remove the cover and all the oil has leaked out the tank and into the bottom cowl of the motor. I checked all the oil hoses and they appear to be ok. Can anyone tell me what maybe causing this problem. Has anyone experienced this problem before?

May have a crack in oil tank.

I agree. Stop using the oil tank and just pre-mix the oil with your gas. It's so much easier. Remember it runs a 50:1 pre-mix.
