I have a 2006 205 Sport with a 5.0 L MerCruiser Chevy engine that was purchased new. Recently when we were just on the water I found that the engine had blown a drain plug out of the side of the engine block. Obviously it was blowing water and the pump started pumping water out the side, or I wouldn't even have known the problem. Since I didn't have any spare drain plugs, this ended our day. After purchasing and installing the plug, everything is now fine and running smoothly.
My question is why it happened, and can I expect it to happen again? I thought maybe since the plugs were plastic that they deteriorate over time and I should replace all of them. Anyone else experience this or have any thoughts?
Thank you,
