Hey guys, it's still winter here in the Midwest, and my 2001 gti is still in storage but I want to fix the speedometer soon. What are the common problems that cause a seadoo speedometer to not work? It has the paddle wheel, and the paddle wheel spins freely. The speedometer is also an analog style, what should I look for first when diagnosing the problem?

It’s typically the gauge if the paddle wheel is fine.

I installed the CanDoo Pro GPS speedometer module and it works great for me.

See but my only concern on that is, what if I drop 130 on the module and the gauge is the culprit of the problem?

I would think the gauge reads resistance and grounding it might go to full speed but I’m not sure so you could risk frying it too.

from the manual

To check if the speed sensor is operational, disconnect
the speed sensor connector housing
from inside bilge.
Using an appropriate terminal remover (Snap-on
TT600-4), remove the PURPLE/YELLOW and
BLACK/ORANGE wires from the tab housing of
the speed sensor.
Reconnect the PURPLE/YELLOW and BLACK/
ORANGE wires in the receptacle housing.
Connect the positive probe of a multimeter to
speed sensor PURPLE/YELLOW wire and the
negative probe to speed sensor BLACK/ORANGE
wire.
With the safety lanyard removed, depress the start/
stop button to activate the MPEM timer.
Slowly rotate the paddle wheel. Every 1/8 turn, the
observed voltage should fluctuate between 5.5
and 8.5 Vdc.
