I have a 2005 150CC w/ a Yamaha 50HP 2 stroke. I purchased this boat in February 2006.

If I do not start the boat for a week to 10 days my battery goes dead. I tired tracing a short, but I am not too sure how to go about this. I removed all negative wires from my battery, turned my ohm meter on, and put the black probe on the negative wires, and the red probe on the positive terminal. It shows a draw of 0.35. Then I tried this with the bilge pump plug disconnected in the stern hatch. It then showed a 1.92 draw. The present reading at the terminals is 13.14

Since I got the boat, I added an hour meter and an AM/FM/CD player. I thought the radio memory was the draw, but I disconnected the radio and the draw is still there.

The depth finder, VHF, and AM/FM are all drawing their power from the Nav / Anchor light switch....apparently the way the previous owner did the wiring. Even with these wires disconnected, I am still drawing 0.35.

What can be causing this, and how can I go about fixing it....and will this amout of a draw cause the battery to die.

Thanks,
