all electrical power to boat shuts off and turns on when ever it feels like it. May turn off for 1 min or 10 min. then just turns itself back on. But power still there for the boat to start. I lose everything from stero to blower. Please send me some advice
thanks

Safety Switch(if your boat is equipped) may cause this, sometimes the little prong that holds the switch down gets weak.

I put a dime under the prong on mine to make up the difference

If the boat will still start / run then the problem is probably going to be up under the dash. Like Nacho indicated, the problme could be in either the power or the ground wire.

I would recommend a visual inspection of the power distribution panel (fuse panel). You may have to take panels off to get to the back so you can see where the wires attach. Look at everything, wiggle everything. What you are looking for is something loose.

If all the connections are ring terminals then I would be looking for a loose screw. If you have push on terminals then there is a possibility that one of them has lost its grip and if you tug on it lightly it will pull off way to easily.

Since you lose power to almost everything it indicates that the problem is in one of the main wires.

If the panel has a "main" fuse I would pull it and inspect carefully. Make sure that the fuse has a good spring pressure when it goes back in.

If you can't find the problem by inspection then I would rig up some diagnostics. Rig up a small 12 volt light bulb on a pair of wires terminated in alligator clips. You may want to put a switch inline so you can turn it off. Start by clippng the light to the main power and ground wires where they come out of the wiring harness up under the dash.

Go ride.

When the electrical system starts acting up, look at the light. If it blinks on and off then the problem is either in the wiring or back at the engine where the power and ground wires originate.

If the light stays on steady while everything else is going on and off then the problem is somewhere between where you have the light clipped in and the fuse panel.
