put 60 hours on the motor during the past 15 months.

I just went over 450hrs since April 2002 when I bought my 60 merc 4 stroke. We
are 12 month boaters tho.

Glad to hear the Merc 60 4 stroke is going on 450 hours. Give me confidence
that mine will last a long time

It's still making a little oil but I am changing it every 50 and things seem
fine. It is still a "bump the starter" to start engine that runs smoothly from
about 600rpm up to WOT with no stumbles, chokes or smoke. I'm sold on 4
strokes.
