My 1995 Mercury 135HP 2 StrokeOutboard has decided to overheat whenever the
RPMS are around 1200-2000. Either side it cools off but in this range it
warms up fast. The water pump is working because it streams water ok.
Nothing seems to be bloking the intake.

I have only had the boat for a short while. The previous owner barely put 20
hours on it in 2 years. It was recently serviced by the previous owner as
well.

Any ideas?

Any way I can get hold of a workshop manual in digital format to pull down
and check the water pump?

Regards,
