Hello, my first time posting, i've been a lurker for a while though. I think you guys are so knowlegeable with engines. I have a question, I have 1998 2-stroke johnson 150, I opened the air box and saw what look like oil dripping from the intake manifold, should I be too worry, obviously i should,could you guys tell me what might be the cause and how to fix it. Thank you in advance

Re: oil seen in air intake box

When you tilt the engine fuel often exits the carbs into the box, theres a lower hose that drains into the block for re-circulation of excess fuel. Normal.
