My Sailfish 23-foot walk around with a 1997 Yamaha 250-HP two-stroke outboard motor is not working properly. The boat was in the water this winter and we didn't run it for about two months. This weekend BATTERY-1 died--so much for the solar charger--and there was about 6-inches of water in the cabin. I switched to BATTERY-2. It was also low and did not have enough juice to crank the engine. But it did drain most of the water before it, too, died. So I hooked up the portable jump start battery to BATTERY-1 and the engine fired up. We cruised up the N.C. waterway listening to the radio, which at some point I noticed turned off mysterioulsy. We stopped for lunch, engine fired up and we cruised home. About an hour's ride total.

Later I noticed no cabin lights, nav lights, radio, VHF, or bilge will come on. I tried to crank and no juice. Thinking I had left something on I charged and started the engine again. But still even after running for 15 minutes nothing electric will come on.

Any thoughts?

Check for a loose ground. The batteries must run to a common ground bar that might have a loose (corroded) connection.

Chuck - everything is connected to be run off either or both batteries.

And in the last paragraph of the original post I left out an important "not"

I noticed that all the accessories would "not" come on so I charged the battery #1 cranked the engine and still not accessories. I charged the batteries on "all" and so it must be common between both.

Thanks for the help I'll check on the ground.

How about an in line fuse/circuit breaker between the battery/switch and the positive accessory panel bus bar?

When there are problems with battery operated electrical devices, first thing to check is the battery.

Did you solve your electrical problem?

6 inches of water in the cabin for a long time could have let the water wick up into something that's now shorted out ,,i have seen wires spliced together just to get the right length when it should have been one piece and no splices
