Crappieseeker, It very well could be tied into your ignition switch. Just turn the motor ignition on long enough to see if it works that way. I think you mentioned your boat has an Optimax engine which I know has a computer. I wouldn't want to leave the ignition on for a long period of time without the engine running, but it wouldn't hurt for the minute it takes to test the D/F. If it is tied into the ignition switch and you would rather have it available to use while the engine isn't running, you could just rewire the hot wire to the battery or the anchor light switch. The anchor light switch has power to it at all times. Just make sure it is fused. I know alot of guys, myself included, don't use the kill switch that clips to your belt. Might be a good idea to use that if you are a new boater as that rig of your's should smoke with the 90 on it. When are you gonna get it wet? Let's hear some reports and see some pictures!
