Hi, I replaced the temp gauge and in the process think I may have blown the ignition fuse. Prior to the temp gauge re-installation, the boat started every time. Now I turn the key and nothing. I checked the fuse panel under the instrument panel but there was no ignition fuse. Physically, I cannot find where the ignition fuse lives. Is this under the instrument panel or somewhere near the sterndrive?

thanks

Ayuh,...... Welcome Aboard,...... There should be a 50 amp breaker on the top or side of the motor, it's got a red reset button on it,.....
There's also a 90 amp fuse block on the starter, where the battery wire comes in,.....
It's a little 1/2" square affair,....

Follow the red/purple wire from the key switch. Look for a 20amp inline fuse

Some times the power is daisy chained through the gauges in series. check for 12 v supply to key switch. May have missed a wire connection on suuply power when replacing gauge

Glass inline fuse, 20A, in the red/purple wire that runs from the ignition switch. Cut that horrible thing out and replace it with a mini blade fuse and holder...

Forgive me for asking…but have you knocked the safety kill switch lanyard out of position or is it in gear ?
