Hello, my name is***** will assist you.

Do you have a multimeter to do some testing?

Does the boat have a volt gauge?

Customer: replied 5 months ago.

SWe can test it for sure. You will also need to be able to start the engine and allow it to run. Do you have a set of gearcase muffs or is the boat in the water?

Customer: replied 5 months ago.
It's on the trailer, no muffs

The only way to know for sure is to get the engine running. We cannot do so without water, you will destroy the water pump.

Once on water what do I do
Expert:  Charles replied 5 months ago.

Hook the meter directly to the battery. Record the voltage that the meter shows. Then start the engine. The voltage should come up slowly to around 13V. raise the RPM of the engine to around 2000. At this speed the voltage should be close to 14.4V DC. If you are getting reading close to this, the battery is charging.
