I agree, startup blue smoke is usually leaking down the valves. I would
live with it if it is not a lot.

2001 Mercruiser 4.3L, low hous, runs well, strong and starts reliably.
Recently noticed a bit of blue smoke after start. Dissipates fast. Oil
level slightly above the full mark on dipstick?

Any clues as to why this is happening?
