power issues

Had a leak where the depth finder is. Drained the battery. Installed new battery, now no accessories (Horn, blower, bilge pump) will work. Dash is completely dark. Is there a reset on the system wil there is no power to the boat for 10 min?? Any advance is greatly appreciated.

Having issues with one engine seems to not have full power with take off. Can't pull up skier. Once boat levels off then ok. We have owned this from the start. Never have had any issues. It is almost like there are weeds in the impeller but everything checks out. Thanks for any help new to...
