Hmmm. More info:

[From a different boating forum here in the US; response to someone whose gauge was reading somewhat wacko]:

What type of Gauge do you have? If you have a Yamaha multifunction spedo you may have your dip switches set incorrectly. There are three settings; Yamaha, USA, and Europe. If they were set to Europe your fuel gauge would work in reverse (show full when empty and vice versa) but if they are set to Yamaha then your fuel level may indicate as you have said. The USA setting is used for most fuel senders. This is something that the dealer should have checked before delivery.


This implies that the Euro standard is opposite the US (decreasing resistance as the tank empties, or vice versa; don't ask me...) In either case, sounds like your problem.

Hi Tim
I had the same problem on my fast fisher, the cause is that the float on the sender has been mounted the wrong way round. The cure is to remove the sender and slide the arm out and refit the opposite way round. What should happen is the resistance should decrease as the float raises, but by fitting the float arm the wrong way round the resistance is at minimum with the float down and increases as the float rises as you add fuel.
Hope this helps.

Or, you could move to Australia, where everything is upside-down anyway.

So can some one tell me if a 240-33 Ohm is US or Euro

Just found out it is US, thanks to Steven at A.S.A.P. Supplies Ltd

THanks for all the replies. The arm being the wrong way round sounds the most likley as the gauge is very accurate, but the wrong way round. I wuold have thought that if the resistance was wrong for this gauge then it woulnd't be as accurate.

NO power goes to the gas tank at any time, ground and Send only,
