Speedo Failure?

[Crawfy]

I have a 2007 DF90, over the last number of trips the speedo has begun playing up, one minute it's fine next you look down and it's not working. The REV guage is fine/
What could be the problem, engine HRS approx 120hrs.

Cheers

How do you have the speedometer hooked up?

Speedo

Clean hole to Speedo Gauge and blow out hose from front to back. Made sure to disconnect hose at engine and clean and blow out small hole on leading edge of lower unit.
