New Battery, boat won't turnover

So a few weeks ago I made a rookie mistake of leaving the key in on position and didn’t turn master battery switch to off. The next week couldn’t muster enough juice to turn it over. Tried charging the battery but couldn’t bring it back to life. Bought new battery yesterday and hooked up. However, I’m not getting anything when I turn the key one click, no fuel gauge movement, trim, etc. But when I turn the master power switch on, I can get radio, horn, fish finder to work. Does anyone know what may be causing this issue, what I should check?

I'd suggest rechecking the work you did....cable ends clean....and tight?

If they are okay, check for a main fuse or circuit breaker.....If the battery's voltage has made it to the 'dash' (key switch), you may want to verify the switch functions (routes current to the RUN and START terminals...
 
Radio, horn and fish finder are not likely powered through the key switch. At least they shouldn't be. First check all of your fuses on the engine.
