I bought and installed a Humminbird Pirhana4(I know should have bought an Eagle) this weekend. It works fine when the boat is off. As soon as I turn the boat on it freezes.Any ideas about what I did wrong or why it freezes?

"Feezes", is the display still on?<br />What power source did you connect it to?<br />Are you sure it is well grounded?<br />What ground source are you connecting to?<br /><br />Do you have a meter? Can you check the source voltage to check for a low/high voltage condition when the engine is running or when the key is on?<br /><br />If you can connect it directly to the battery both positive and negative when you are under way and it works fine, it would seem you have a high/low voltage condition when the boat is running.<br /><br />Another thought is: is your battery (or both) in good condition, as well as the charging circuit.<br /><br />Safe boating to all.<br /><br />Cheers.<br /><br />emp.

I had the same problem with my piranha 1, I was to close to the engine and not far enough under the water. no I read at 35 knots, but it still doesen't work in reverse. try moving it with the engine running (carefully)until you find the sweet spot
