Hello guys and gals quick question. I have a 7.4 Mercruiser W/bravo outdrive...During my recent trip to block island from mystic ct my Alarm started sounding, after going through a checklist i noticed that the Outdrive oil reservoir bottle I believe in the back was completely empty. The entire contents of the bottle were in the engine compartment. Every now and then for the past month i have seen on occasion a oil slick to the rear of my boat so obviously this is where that was coming from. This is a very slow leak...The bottle itself doesn?t appear to be cracked or broken any ideas where she would be leaking from?
