So I think I figured out my battery problem the cables on the terminals weren't tight enough and figured that's why my batteries weren't charging. So today I but some lock washers on and tightened the terminals down well.
So my question is when I have the earmuffs on and running the boat at idle is the voltage gauge suppose to read 12v and not till I rev the engine it will rise pass 12v? When I did rev the engine the needle did rise but not much
Does the boat have to running at a higher rpm to show over 12v?

Low charging voltage might indicate a discharged battery and low amperage charge rate. Let the battery rest (after running the motor or being on a charger) for at least half an hour and then check the battery voltage with the engine turned off. Most older engines have little charging output at idle.

Older outboard motors do not have large charging systems compared to today's models.
At idle, there will be a slight charging of the batteries.
Remember, do
not exceed 1000 rpm's when cooling the motor on the muffs. The cooling system is limited while on the hose.

Ok thanks for the great feed back much appriciated
