Having said that, there shouldn' t be a major difference - more than
10%. Usually, they are pretty close. If you have the air type, take
it off the guage and probe (or motor), blow some air through it and
put the line back. That should bring the two closer together.

Thanks I will give that a try tommorrow.

You might also want to check if you have the probe type, so be sure
the probe is staying in the water and not moving around a lot - also
want to check the exposed part of the line - I've had a leak in the
line and a probe that moved around.

The pick up for my speedometer is in the Outboard. Merc 125 has the buil;t
in pick up tube.

My neighbor's 135 Merc has the same thing, and that damned thing is
always partially clogging up.
