2000 Capri Classic Bowrider - Mercruiser 3.0 4cyl I/O.

During season opener trial run this past Saturday, she was purring along splendidly at 3600 rpm...but I noticed a SLIGHT trickle of water weeping out from between the head and block, just beneath the #2 and #3 spark plug...and a tiny portion of the edge of the head appears to be eroded away in that area (just enough to maybe slide a dime into half way).

Thoughts? Suggestions?

Off with it's head!

Seriously - I would do just that. Those engines are pretty simple to work on, so grab a manual, make sure you have a decent torque wrench and gasket scraper, and pull the top end off (make sure you keep track of which parts came from where so they can go back in the same spot). Probably just a head gasket - which, with an iron head - is probably all that needs doing. New gasket's cheap - make sure the sealing surfaces are spotless, re-assemble according to the manual (new manifold gasket and valve cover gasket etc. as well). Re-tourque the head bolts and manifold bolts after a few hours running and you should be good to go.
