ProStar 197 fuel gauge - Random readings

[swbca]

The 2004 197 fuel gauge has always been imprecise because the fuel shifts left and right across a partition in the tank.  But now the gauge reads random values, most often stuck on empty or stuck on full.   Is this a gauge or sensor problem?

@swbca my buddies MC does this. They say the fix is to fill the boat full. This should reset the sensor. Apparently the cause is that everyone on lakes just adds 5 gallon cans with out filling up. This throws the sensor off for some reason.  He was on the MC promo team for years and this seemed to be a reoccurring issue.

@dave2ball  Your suggestion to fill the tank worked.  Thanks
