We just returned from our 5th outing on our new to us boat, an 02 Islandia. The second outing the fuel gauge quit working........ no biggie but frustrating. Then this weekend was pulling a tuber and my oil warning light in the fuel gauge itself started beeping. Stopped, checked oil, was about a quarter full, put a gallon in putting it well over half, restarted, same prob....... oil warning going off then went to a steady beep! What could be the problem? Engine did not run any different afterwards, just the alarm going off! Any help would be great!!

The oil sender is an easy check to do.
Unplug the the two wires going to the level sender in the engine mounted tank. If the tank is full you should have NO continuity when you check it with a multimeter, and continuity when low or if the sender is bad. Also make sure that the small tank is full to the top. To do this loosen the cap on the small tank and make sure the cap is tight on the large oil reservoir. Hook the engine up to a garden hose and start the water. Then start the engine, and when oil starts to flow out the top of the small tank, tighten the cap and shut the engine off.
This is a pressurised system. If the cap is ever loose on the large tank, or there are any air leaks, it will not keep the small engine mounted tank full.
I need to download the hull manual to look into the fuel level, so I will have to get back to you on that one.

OK. I had a look at the wiring diagram for the fuel gauge, and here is a quick run down on what the wires should do.
Black .... ground for the gauge
Purple .... power for the gauge
Blue .... gauge lighting
Light Blue .... from the oil level sensor
Pink/black and Pink both go to the fuel level sender
First check for a good power and ground to the gauge. If that is good, with the key in the on position, one of the pink wires should have power going to the fuel level sender (diagram does not state which one). If there is no power going out you most likely have a bad gauge, but you can quickly check the resistance of the sender to verify that it is working.
With the sending unit unplugged connect your multimeter between the pink/black wire, and the pink. Full tank should read 28-33 ohms, half tank about 103 ohms, and empty 240-245 ohms.
Hope that helps.
